Top 10 Solar Post Cap Lights

While many of the products we review here are readily available to purchase and operate without a license, we always recommend hiring a qualified electrician to install and demonstrate their use.

In some cases, improper use and installation may result in a breach of insurance. Even worse, you could be putting yourself or your family at risk as an incorrectly installed electrical device could start a fire. So, don’t risk it - seek the services of a fully licensed electrician instead.

If you think parallel parking is difficult, you should see my driveway.

It's almost impossible to park my poor little Fiesta into my driveway in broad daylight but trying to navigate those frightfully acute angles in the dead of night is a near-impossible task.

To make matters worse, it’s on an incredibly steep, often slippery incline. Before I found my solar post cap lights, scratching my car,  was an all too common occurrence.

Top 10 Best Solar Post Cap Lights Reviews

I know there must be others out there like me, thinking there was no affordable way to illuminate their death trap of drive, but there is light at the end of the tunnel, my friend.

Having put in weeks of research to find my own solar post cap lights, I can now use my knowledge to help you on your search for security, sight, or simply something to beautify your garden. 

We’re losing light here, folks, so let’s get right to it!


At first glance, they may not seem like much to look at, but when you actually see them on a garden or drive fence post, there’s a certain understated beauty to this Fooyancho creation.

Beaming from within the tastefully frosted glass lamps are incredibly powerful 400 lm solar bulbs.

Sitting high atop their durable, corrosion-resistant aluminum posts, you’ve got the perfect lighting solution for large, open, dark areas.

Not impressed yet? Let’s talk about couldn’t be easier. You simply fit them to your chosen posts, and the sun takes care of the rest.

That’s right, folks. These lights sunbathe all day, and as soon as dusk washes over, they turn on automatically, providing clear visuals and security the night through.

Once dawn hits, they power themselves down and prepare themselves for soaking up a sunny breakfast.

Made from hardy PVC, they’re designed to survive life out in the elements, so don’t worry about shielding them during extreme weather.

Even in gale force winds, their solid steel bases keep them firmly in place, ready to light your way.

Those with sensitive eyes will also appreciate that you can choose to soften the standard white color to warm (a yellowy color like the pages of old books) or warm white.

Very self-contained, self-managed gadgets, apart from giving them the odd wipe down from time to time, after you have them in place, your job is done, and your land is lit - perfect!


  • 400 lm Per Light - These are incredibly powerful solar lights.
  • 3 Colors - Choose your favorite.
  • Automated - They turn themselves on and off.
  • Weatherproof - Reliable no matter the weather.
  • Price - Pretty standard price to be fair.


  • Brightness - Let’s just say you don’t want any of these near your bedroom window.


These were the first solar lights I encountered on my own mission to illuminate my wretched driveway. They’re some of the most popular on the market, and I’m not at all surprised by that.

Just look at the metal forming an elegant hair ribbon shape across the lantern. It’s not too much, it’s not too little. To quote Goldilocks before the bear incident…“it’s just right”.

Fortunately, this elegance stretches into the functionality of their design as well. Using a proprietary Flexfit base, if your post is anywhere between 4 and 6 inches, square or circular, they’ll fit just fine.

Furthermore, as a completely self-contained unit, don’t worry about calling in an electrician.

All you need to do is fit it securely on your chosen post or pillar, and voilà! The darkness is banished and shall remain so for at least 100,000 hours.

Despite their pretty design, make no mistake, these things are tough as old boots. Featuring an automotive-grade, waterproof lithium-ion battery, tempered glass, and a UV-resistant plastic coating, they can certainly roll with the punches.

Given their 25 lumen brightness (3000K) and wide bases, I’d recommend these as pillar markers for a driveway.

They won’t necessarily saturate the area with light, but they will be perfect for guiding you into a tight spot after a late night at the office.


  • Flexfit Base - Fits a wide variety of posts.
  • Aesthetics - These are works of art.
  • Weatherproof - Don’t worry about bringing these indoors when the snow falls.
  • Lithium-Ion - Efficient battery.
  • Automated - No manual interference required.


  • 25 Lumens - Not the brightest.
  • One Lighting Choice - It’s warm white or nothing, folks.


If you’re going for the full-on 1800s London look, check this Kemeco creation out. Arriving at an intersection between traditionalism and modernism, their classic look belies their state-of-the-art solar technology.

Capable of dishing out 150 lm, and containing precisely zero harmful chemicals, the Ni-MH batteries are the perfect green solution to your dark zone conundrums.

For 6 to 8 hours a night, your drive, walkway, or garden will be practically drenched in light.

Despite their impressive performance, my favorite thing about this light has got to be the build quality. This is the real deal, friends. You won’t find a shred of plastic.

Crafted from cast aluminum and fitted with ripple-effect glass, they look and feel amazing. What’s more, they’re completely weatherproof, so don’t treat them preciously.

Just give the solar panel a wipe down with a damp cloth once every so often, and that’s that.

Unlike many other outdoor solar lights that come in sets, the ST4311AQ is a standalone feature, and due to the up-market design, it costs a pretty penny too.

Don’t let that scare you off, though. If you can source the funds, a couple of these automated lights are well worth it.


  • 150 lm - Bright enough to light your way.
  • Build Quality - Unparalleled design. No plastic.
  • Weatherproof - They handle heat and cold incredibly well.
  • Aesthetics - From the traditional shaping to the rippled glass, they’re truly breathtaking.
  • Automated - Once fitted, your work is done.


  • Price - Premium product means a premium price tag.
  • Screws - The included screws rust, so it may be worth buying some spares or priming them.


If you liked the look of my second pick, but they’re a little rich for your blood, this BlueYang variant might hit the spot.

Their charmingly antiquated look may be the perfect accent for taller posts, and thanks to the incredibly realistic dancing flame effect, they feel homey and unique.

But can they handle tough climates? I’m pleased to say, yes, they can.

They’re corrosion-resistant, shatterproof, and totally waterproof, so you can bet your bottom dollar that flame keeps a-flickering’ come rain or snow.

They’re an entirely ABS design, which is a little disappointing, but it does help to keep their weight down, making installation a total breeze.

Speaking of installation, setting these lights up is as simple as slipping the pieces into one another and fitting them with screws. Just remember to turn them on first as the power switch is inside the lantern.

With lithium-ion batteries at the core of this beautiful solar light design, you can expect up to 8 hours of illumination during the summer months and roughly 5 when winter takes hold.

Their flickering effect makes them a beautiful mood enhancer for those summer nights spent conversing and sharing some cold ones in the yard after a day of BBQs with friends and family.


  • Dancing Flame LED - Realistic flame adds a beautiful ambiance to the environment.
  • Weatherproof - Your year-round outdoor lighting solution.
  • Aesthetics - They look fantastic if you ask me.
  • Lithium-Ion - Fairly decent battery type.


  • Thin Wires - Can break easily if you’re not careful.
  • Plastic-Heavy - No metal or glass to be found.


Beautifying any outdoor environment, these twinkly SunnyPark solar lights allow you to make a constellation of your garden.

The crackle-effect crystal glass enclosures add tons of character to the 5 lm output, so if you’re looking for something with a bit of a signature, these could be the ones for you.

Of course, 5 lm isn’t nearly enough to highlight the ground, so if you’re looking for a floodlight effect, feel free to scroll on by. What these lights excel at is turning your dark garden into a sparkling evening grotto.

Made of plastic rather than metal, the bases could certainly be sturdier, but considering the amazing price tag and the fact they come as a pack of four, this seems like a fair compromise.

Powered by chemical-free Ni-MH batteries, these little, earthbound celestials, are great for your garden, your energy bill, and the environment.

In addition, the solar panels they’re hooked up to are of respectable quality, ensuring they shine the night through.

Designed to fit flush on 4x4 posts, installation is simple, but it’s worth testing them for a night first because there is no easy access to the battery once they’re fitted.

I’m currently working on my back yard and garden, but as soon as the big jobs are done, one of the finishing touches will be two sets of these gorgeous lights threaded around my seating and chiminea area. I can’t wait!


  • Crackle Crystal Glass - Real crackle glass gives the light a scintillating character.
  • Ni-MH - Eco-friendly, chemical-free batteries.
  • Easy Installation - Couple of screws and you’re done.
  • Price - Very cheap for real glass.


  • Battery Access - You have to unfit them to reach the battery.
  • 5 lm - Not designed for shining light across wide areas.
  • Plastic Base - Keeps the price down, though - hurray!


Bringing a bit of Moroccan spirit to my sixth spot, these Siedinlar solar lights might be just the thing you're looking for to spice up your property.

Featuring a beautiful metal patterning across the lamp, they emit a radiant, 3000K, warm white light with intricate shadowing.

They have a 15 lm brightness rating, so I can’t recommend them as floodlighting, but they make for some incredibly majestic post markers or inviting garden decorations.

It’s actually a good job they’re not too bright because the detailed patterning makes them a truly mesmerizing visual prospect, one that’s hard not to get lost in.

Crafted from corrosion-resistant metal, they’re well-equipped to handle the odd storm, and the Ni-MH batteries are both great for the environment and provide 30,000 hours of luminosity.

Furthermore, to sweeten the deal, Siedinlar offers a 1-year full warranty should you not be completely satisfied with their products - perfect!


  • Corrosion Resistant - They don’t mind a bit of weather.
  • Decorative Patterning - Enthralling lighting effect.
  • 1-Year Warranty - Free replacements in the unlikely event that they malfunction.
  • Price - A pack of two for less than $30? That’s a steal!
  • Ni-MH - Eco-friendly battery - woo-hoo!


  • Heavily stylized - Not really a neutral design.
  • 15 lm - Only decorative lighting.


These beautiful solar post cap lights have a modern look emphasized by the broken-line pattern of the plastic casing and their white coloring.

These work perfectly as markers for a driveway, path, deck, or (if you’re lucky enough) a pool, but the 5 lm brilliance won’t be enough to saturate an area.

Fitting snug on any 4x4 or 5x5 post, they’re a fairly versatile lighting solution, and they look fantastic.

The white acts as a lovely accent color amongst the lush greenery of a garden; however, they will appear to get dirtier faster, so I recommend giving them a wipe down at least once a month.

If you don’t like the white, they’re also available in black and gray.

Entirely self-contained and automated, once these bad boys are fitted, you can kick back and enjoy your sparkling outdoor area, invite a few friends round, and have a cold one by lamp and moonlight.

They give off quite a cool, crisp, white light, which would normally be a little jarring for relaxing and socializing, but as it’s so gentle and filtered through warbled glass, it really only adds an inviting atmosphere to the environment.


  • Real Warbled Glass - Takes the edge of the bright white light.
  • Weatherproof - Designed for a life outdoors.
  • Aesthetics - They look lovely.


  • Plastic Casing - I’d prefer metal.
  • 5 lm - Very mild lighting.


These Maggift lights are all about accenting your walkways. Their low-profile design and slit lamp are a great way to imbue your garden with light without the often imposing structure of solar lights.

Measuring only 2.4” high, they’re a non-obtrusive answer to your dark zone dilemma. The 15 lm LEDs gleam through the letterbox style panels, providing clean crisp lines of light to guide your way in the evening.

While they are made of plastic, It’s a high-quality ABS, ensuring you’ll get your money's worth.

Completely sealed, the weather has no way of worming its way into the mechanism, so don’t worry about bringing these lights in when it gets a little choppy. 

That said, for peace of mind, Maggift does recommend giving them shelter during rainstorms.

As long as they have access to direct sunlight, these solar lights will last all night long, making them the ultimate lighting device for your next party.

As you’ll see for yourself, they do have a fairly modern aesthetic, which means they’ll go down a treat in neat, open plan gardens, but may look a little out of place in a more traditional environment.

Should they match the style of your outdoor area, you won’t be disappointed. They’re durable, discrete, affordable, and couldn’t be easier to install.


  • ABS Construction - Not metal, but ABS is the next best thing.
  • Weatherproof - They don’t mind getting caught in the snow (but cover them during intense rainstorms).
  • Price - Get six of these for half the price of my premium Kemeco pick.
  • Modern Look - Letterbox paneling has a futuristic vibe.


  • Stylized - Not such a versatile look.
  • 15 lm - They’re markers rather than illuminators.


In our final position, we have another Seidinlar creation. Whereas my earlier Seidinlar pick was heavily patterned, these lamps have more of a classic, neutral look, ensuring they’ll fit right into place no matter what style of garden you have.

If you’d like the option to switch between cool and warm lighting depending on the situation and how you’re feeling, look no further.

These are the solar post cap lights for you. To change the color temperature, all you need to do is twist the cap off, and flick the internal switch. It’s a quick and easy process, although if you have a lot of them, it can be a pretty monotonous task.

What impresses me about these lights is the quality of the solar panels.

Affordable solar lights can have real problems absorbing energy without direct sun exposure, but these soak up plenty of energy on gray days. If you live in a drizzly climate, these will help you make the most of the meager amount of sun available.


  • Dual Color Temperature - Warm and cozy or cool and crisp? It’s up to you.
  • Quality Solar Panels - Gain plenty of energy on overcast days.
  • Aesthetics - Timeless design means they’ll never go out of style.
  • Price - Great product for the price.
  • Versatility - Fits 4x4, 5x5, and 6x6 posts.


  • 10 lm - Not too bright.
  • 4x4 Compatibility - They do fit on 4x4 posts, but they overhang quite a bit.

Top 10 Solar Post Cap Lights - Buyer’s Guide

There are some truly beautiful solar post lights on this list, aren't there? But as tempted as you may be to add some to your cart and confirm the purchase, it’s best you run over a few solar light essentials first.


Many (including myself) at some point erroneously believe that the wattage of a light is a measure of its brilliance or brightness. Being that the power of many electrical items is measured in watts, it’s no surprise really. However, the word you need to keep an eye out for when shopping for lights is lumens.

Lumens are the true measure of a light’s brightness. Let’s start with some examples of lumens to give you a bit of context. A torch with a lumen rating of 1000 will reach roughly 220 yards into the darkness, and the sun emits about 98,000 lux (lumens per square meter).

If you want your solar post cap light to simply mark the location of a post or give your yard or garden a fairy hideaway vibe, you can settle for something between 5 and 50 lumens. They won’t light up their surroundings, but they will be visible from a distance and add a twinkly aesthetic to the area.

For a decorative light that does offer a small amount of illumination, you should be looking for something to the tune of 100 - 150 lumens. A solar post cap light that brightens up a wide area will have a lumen rating upwards of 150.

If you do end up dabbling with high lumen ratings, please do take into account how it will affect your cohabitants and neighbors. Fitting a supernova of a solar light right outside someone’s windows is likely to be a cause of contention.

Solar Panel Type and Efficiency

You’d be forgiven for thinking a solar panel is a solar panel and that’s that, but there are actually four different types of solar panel, each with its own characteristics.

Monocrystalline Panels


  • Efficiency rate = ∼20%
  • Works better in extreme weather.
  • Doesn’t need as much direct sunlight to charge
  • Longer lifespan


  • Expensive
  • More waste during production.

Mono panels are made up of cells crafted from a singular silicone ingot, which sounds as complicated as it is. All you really need to know is that this oneness of construction makes them more efficient than poly panels.

Polycrystalline Panels


  • More affordable
  • More sustainable production methods.


  • Efficiency rate = ∼15%
  • Shorter lifespan

Poly panels are a much more affordable option, but they don’t last as long as their mono counterparts. Having said that, their production doesn’t cause anywhere near as much waste.

Amorphous Silicon


  • Highly efficient
  • Work well in extreme conditions.
  • Work well in overcast weather conditions.


  • Even more expensive than mono panels.
  • Need a large surface area.

Amorphous silicon panels utilize something known as uni-solar triple junction cell technology. Put simply, it allows them to absorb a wider gamut of the light spectrum.

Consequently, they’re more efficient than mono panels, in both direct sun and during overcast days. They’re also more resilient than mono panels in extreme temperatures. The only drawback is that they require a much larger surface area to reach the same output as a mono panel.

Concentrated PV Cell Panels


  • Most efficient


  • Most expensive
  • Pretty much nonexistent in post cap lights.

You’re unlikely to encounter these kinds of panels on your search for post cap solar lights, but I thought I’d run over it anyway just so all the bases are covered. This is the most advanced solar panel technology. Using optical light collectors, concentrated light is herded into the solar cells, bringing battery charge times to a minimum.

Color and Temperature

Much like you can have a favorite color, people have preferred shades of light. Sometimes choosing a certain shade is essential to prevent eye strain and headaches. Other times, it’s simply a stylistic choice.

Either way, deciding on a personal favorite shade of light is a great way to narrow down your options and find what you’re looking for quicker.

The solar post cap lights I ended up buying emit a bright yet warm white. Initially, I chose a pair of lights with a strong sheer white glow, but I had to return them because they hurt my eyes.

You may even decide that you want to do away with white altogether and choose something like the BlueYang fire glow lights. It’s entirely up to you.

Color temperature is measured in a unit known as kelvin (K). The higher the kelvin rate, the cooler the color of light will appear - think stark whites or chilly blues. The lower the color temperature is, the warmer the light will appear - think ambers and yellows. It’s important not to get this confused.

Color temperatures between 2500 and 4000K are typically recommended for residential outdoor areas, but you can settle for something between 2500 and 2700K as an architectural accent.

Should you really want to saturate a landscape with light, 3000 to 4000K is a solid choice, but remember, these are all just vague guidelines. If you’re unsure what shade you’d prefer, think about the light bulbs in your house. Are they stark white, or do they have a softer profile? Match the tone that you like indoors with your outdoor lights, and you’re onto a winner.

Here’s a basic guide to help you envisage what might work for you…

2000 - 3000K = Soft White - These color temperatures evoke a cozy vibe and the light has a fluffy character. They’re perfect for evening indoor lighting or exterior decoration.

3100 - 4500 = Cool White - This temperature isn’t quite so soothing. It’s vibrant and invigorating, making it perfect for task lighting, work environments, and rooms of the house with mirrors in such as the bathroom.

4600 - 6500 = What We’d Consider Bright White - This temperature has an incredibly crisp tone so is often preferred in detail-oriented scenarios such as security and product displays.

Rated Capacity (Peak Sun)

Here’s where watts come into play. The rated capacity of a solar panel is the maximum amount of energy it can soak up from the sun in optimal conditions, i.e. during an absolute scorcher, and it’s measured in watts.

You don’t have to worry too much about this as it only really applies to larger solar panels used for powering households. As your little lamps will almost definitely get all the juice they need for a good few hours of evening illumination, you’re good to go. If you are interested in sourcing a high-capacity solar light, the higher the wattage, the better.


I know what you’re thinking...batteries? I thought this was a buyer’s guide for solar-powered lights. You’re right of course, but solar lights still have batteries. It’s where they store up all the power they collect in the daytime and where they draw it from come evening.

Lead Acid Batteries - Lead acid batteries are your most affordable option, but they’re cheap for a reason. They require more power to fully charge, which can be tough in the winter months, and they’re fairly volatile when exposed to the elements.

Lithium-Ion Batteries - LI batteries are much more advanced power technology. They have a longer service life and only require 3.7v to fully charge as opposed to 12v of their lead acid counterparts. On the other hand, they cost more, and extreme weather can affect their performance.

Lithium-Ion Phosphate Batteries - These are the best of all the batteries. They last roughly 50% longer than lead acid, they’re highly stable in extreme temperatures, and they only need to gobble 3.2v of sun. That means that they’ll work solidly through the winter months! The only drawback is, you’ve guessed it...the price tag.

Nickel-Metal Hydride - Lasting roughly 2 years, Ni-MH batteries aren’t exactly high performance gizmos, but they’re affordable, compact, and have zero harmful chemicals in them.

Charging Time and Battery Life

We’ve covered the specific types of battery you can expect to encounter, but we should still discuss charging time and battery life. Ideally, your light will get all it needs over a 7 to 8-hour period, as that’s roughly the amount of daylight it will be exposed to.

If you plan on putting your solar post cap light in a largely shaded area, it’s important you find one with a lithium-ion phosphate battery. The short charge time will ensure it gets enough juice from the limited solar exposure to power on between 8 and 12 hours in the evening.


Solar post cap lights have to brave all manner of weather conditions, so quality materials and a durable build is essential. Stainless steel and cast aluminum are a shoo-in for the job as they don’t rust, and they’re incredibly strong.

More expensive options will come with real glass panels in the lamp, but this can be a shatter hazard. Try and find out if the manufacturer has treated the glass to make it safer and stronger.

More often than not, the transparent enclosure will be made of ABS or PVC plastic. Both of these materials are awesome, so it doesn’t really matter what you shoot for. PVC is the more flexible, but ABS is stronger overall.


Post cap lights can be tiny little things, or they can be great beacons. It’s up to you to decide what’s suitable for your problem area.

I’d recommend taking some accurate measurements of the posts or pillars you plan on fitting them on before you start shopping around. If the base of the light(s) you end up with far exceeds the width of the post, it’s going to look pretty silly. Likewise, a minuscule light on a Grecian pillar will look completely out of place.

Automatic Activation and Deactivation

One of the best aspects of solar lighting is its independence. They rest through the day, absorbing energy from the sun, then burst into action come dusk, but did you know they’re not all automated?

Don’t take it as a given that your cap light has this nifty feature. Some are powered on and off manually. This isn’t necessarily a bad thing, as it offers you a more adjustable lighting experience, but it is more time and energy consuming. Only you can decide which is best for you. One brings convenience, the other, flexibility.

Special Features

Certain solar post cap lights bring more to the table than automation. Some will have multiple lighting modes, or perhaps motion detectors - a definite boon if you’re on the hunt for security lighting.


Solar lights vary in price a great deal, so it’s hard to pin down exactly what you should be saving for the purchase, especially as you may be looking for multiple units.

Generally speaking, they seem to cost anywhere between $20 and $150 depending on the quality of the build, functionality, and the stature of the brand in the industry. My only advice is that if you are looking for numerous cap lights, buy cheaper because it all adds up.


Available in a range of designs, finding solar post cap lights that suit your aesthetic is probably the most challenging part of the consumer process. Key things to think about are profile - what sort of shape are you looking for? And general design - what sort of patterning across the lamp do you want?

Warranty - Just In Case

I’d highly recommend settling on some solar lights that have a decent extended warranty, especially if you plan on bringing some glow to your garden on a budget. 

As mentioned earlier, solar lights take a fair amount of abuse out there exposed to the elements, so fault or breakage isn’t exactly uncommon. Even if it’s slightly more expensive, choosing one with a reasonable warranty is worth every penny for the peace of mind it brings.

Solar Light Maintenance - How to Give Your SPCL some TLC

Good solar post cap lights don’t need much attention, but if you really want them to last, it doesn’t hurt to take a few of these great tips on board.

  1. Cleaning or Replacing Batteries - The best thing you can do to ensure they keep lighting your darkness.
  2. Clean the Lamps and Panels - A cloth and some warm soapy water are all it takes, although try to find a soap that doesn’t leave a residue as it could block some sunlight from the panel.
  3. A Thought for the Weather - Do you live in a snowy place? You may need to change the battery at least once every two years.
  4. A Second Coat - A thin coat of translucent spray paint can protect your lamp from the accumulation of dust.
  5. Clear the Way - Prune any trees hanging over your lights.
  6. Storage - When the weather gets extreme, if you’re not going to need them, why not bring them inside? Turn them off, and give them a little sanctuary.

Installing Solar Post Cap Lights - Getting the Job Done

  1. Read the Manual - Installation rarely takes more than a drill and a few screws, but there may be a few limitations in regard to placement that the manual will make clear.
  2. Exposure - When picking a location for your lights, prioritize sun exposure.
  3. Tool Time - Usually, you’ll need to drill holes in the base of a solar cap light in order to fit it to a post. However, certain designs slip on top of your post and are screwed in from the sides.
  4. Aim for Sturdiness - Try to avoid installing your lights on the wonk, as this puts extra strain on their structure and wiring.
  5. Turn Them On - Don’t forget to power your lights on once installed. They need to start charging right away.

  • They’re not as bright as standard lights.
  • As they’re heavily reliant on sun exposure, in many areas, they’d be completely useless.

What Are the Best Solar Fence Post Lights?

As they emit a whopping 400 lumens and give you a choice between three color temperatures, Fooyancho’s solar post lights are technically the best, but they may not be right for you.

Before you can decide which solar post cap lights are right for your property, you need to consider the weather, the dimensions of your fence posts, what you want the light to do, and how you want the light to look.

How Many Lumens Should Solar Light Have?

For the most part, solar post cap lights will have a lumens rating between 5 and 30, but that’s not to say you can’t find more powerful ones. If you’re looking for a solar light that will actually illuminate an area, you should be looking for something between 150 and 400 lumens.

How Long Will a Solar Post Light Last?

How long your solar post cap lights will last depends on a few variables, but generally speaking, you should be looking at a service life between two and three years. When they stop working, a quick battery change is normally all that’s required.

In terms of how long a solar post cap light will last per charge, you should expect something between 8 and 12 hours, and between 4 and 6 hours in poor weather conditions.

Can I Turn My Solar Post Cap Light Off?

Yes, for the most part, you’ll be able to switch off your solar light if you need to, but bear in mind, once powered down, they won’t be able to collect solar energy. If you want to use them again, remember to turn them on in the morning, so they’re ready to guide your way come night tide.

Do Solar Post Cap Lights Work?

As long as they have a good amount of sun exposure, yes, solar post cap lights work a charm. The quality of the solar panels varies from light to light, so some will be more efficient than others, but even poor-quality units should illuminate your chosen area during all sociable evening hours.

How Bright is 300 Lumens?

300 Lumens is pretty bright for a solar post cap light. It’s certainly bright enough to highlight a fairly wide area, making it perfect for solving visibility issues. 100 lumens is usually considered bright enough to light a walkway, so you’re in safe hands with 300.

Will Solar Post cap Lights Work After an Overcast Day?

A cloudy day will never block 100% of the sun's rays, so even if the weather’s looking a tad grim, your little lights should still be getting at least a small amount of power.

As mentioned in the Buyer’s Guide, the type of battery your solar lights use has a huge effect on the amount of sun exposure they need to charge.

In light of this (see what I did there), it’s hard to say how long they will run for in this drizzly scenario, but you may be looking at around 4 to 6 hours of light.

Do Solar Post Cap Lights Come with Batteries?

As they’re a specialist design, most solar post cap lights do arrive with their own batteries, so don’t worry too much about making separate purchases right away. They’re very much designed for speedy installation and instant action. Having said that, you will eventually need to replace them, and take it from me, it’s easy to forget, So if I were you, I’d purchase some spares sooner rather than later.

Why Do Outdoor Solar Lights Stop Working?

If your outdoor solar lights have stopped working prematurely, there’s a good chance that the solar panel has built up a coat of dust or other such debris. This will block the panels from picking up all those lovely rays of sunlight. So, before you blame the batteries and switch them out, a good sponge bath goes a long way with solar lights.

Let There Be Light!

There you have it, friends. That’s about all the advice I have on the subject of solar post cap lights, and now you should have all the information you need to make an informed decision on yours.

Although they’re ranked on my list, there’s something unique about each of my featured solar lights. Just because one is lower down than the others doesn’t mean it won’t be a fine choice for you and your garden. It all depends on the specifics of what you’re looking for. 

I’ve purposefully picked out a wide variety of lighting with the hopes of helping as many people out as possible, and I really hope you’re among them. Do not rage against the dying of the light. Treat yourself to one of these solar post cap masterpieces instead. You won’t be disappointed!
