About this product

【Important—Designed ONLY for 4x4 & 3.5x3.5 Posts】The solar post cap light is exclusively designed for 4x4 inch and 3.5x3.5 inch wooden and vinyl posts. It is not compatible with any other sizes, neither posts smaller than 3.5 inches nor larger than 4.0 inches. Please confirm the actual size of your posts in advance before placing an order to avoid mismatching.

【3 Color Temperatures–One Light, Any Mood】You can easily switch among soft warm white, cool white and natural daylight via the built-in button. It gets rid of single fixed lighting tone, allowing you to freely match proper light effects for warm leisure time, stylish exterior decoration and night safety lighting.

 【2 Brightness Levels–Smarter Solar Runtime】It supports two adjustable brightness modes to meet different using demands. 100% high brightness offers sufficient bright illumination, while 50% low brightness cuts down power consumption effectively and prolongs lighting duration. It ensures the light stays on till dawn smoothly, meanwhile softening light glare for more comfortable visual experience.

【Energy Saving & Durability】Adopts high-efficiency monocrystalline silicon solar panel with photoelectric conversion rate up to 22%, truly zero electricity consumption and eco-friendly. With standard IP65 waterproof performance, it can resist rain, snow and damp environment steadily, realizing long-term stable use without frequent maintenance.

【Easy Installation】Just set your desired lighting mode first, fix the base firmly on the post and tighten the lamp body. No wiring and complicated steps needed. (Note:When installing on a 4x4 post, first remove the built-in 3.5x3.5 adapter from the base)

    Easy Install, Soft Warm Light – Just What I Needed

    These solar post cap lights fit perfectly on my 4x4 fence posts in the front yard. Setup was super easy—no wiring, i even skipped the screws and they were good to go. The warm white glow is subtle but gives off enough light to create a upscale feel on the deck. They’ve held up fine so far and the solar charging has been reliable, giving me light most of the night. Just a heads-up: these are more decorative than super bright, so they’re better for ambiance than strong illumination. Overall, a simple, effective upgrade for the patio.

    Nice warm light

    With summer sun hours, the kolpop post cap lights have been on from dusk to dawn. It would be helpful if the number of LEDs was listed, as that‘s a useful way to estimate light output when comparison shopping similar products. The post cap lights do put out a decent amount of warm white light, nice to look at, with a softer illumination, but not super bright.

    So far these are the nicest and most elegant post cap lights I‘ve tried out

    So far these are the nicest and most elegant post cap lights I‘ve tried out. They have a nice clean, clear and crisp look to the lenses and the lights illuminate pretty well. I like that there is no light leakage through the top of the plastic tops unlike some cheaper post caps. They also come with some decent mounting hardware accessories to give you the option to use these on 4x4 or 3.5x.3.5 posts which is also nice. Overall I‘m very pleased with these.

    A bright idea for porch posts

    I think these will look good on my new porch staircase posts. They don’t give off a whole lot of light but just enough to look nice. The first thing I did was put it out in the sun to let it charge up all day and when I came back and checked it it felt really hot on the solar panel. I opened it up and the battery was really hot. It has one AA rechargeable battery that’s easy to replace if you need to but it was so hot I was concerned. I don’t know if it was getting overcharged or if it was the sun that was just causing the whole thing to heat up like that. Time will tell if it’s going to be a problem, I don’t know if the battery will have a short lifespan. But it works well. There’s no on off switch, there’s just a piece of plastic that interrupts the battery connection and you pull that out and it turns on and stays on whenever the sun goes down. The mounting square that comes with it fit over my 4 x 4 post (actually 3.5“ x 3.5“) and it was a little bit loose but it will be fine once it’s screwed into place with the light on top. It comes with mounting hardware. It’s plastic, and the underside is not air tight or anything so I’m worried that humidity and moisture might eventually collect in the battery compartment. Again, it will take some time to see how long these last. But they’re easy to replace if it does become a problem. I think they look nice and they’re not too expensive.

    Nice Lights but Quality Could Be Better

    These solar post cap lights look good on my deck and give off a nice warm white glow, but I feel the quality could have been better for the price.The plastic housing feels a little cheap, and inside you can clearly see the LED strip through the clear plastic glass. If the glass had been frosted instead, it would have given a much cleaner and more premium look.On the plus side, installation was simple, they fit well on 4x4 and 3.5x3.5 posts, and the solar charging works as expected.Overall, they do the job and look nice from a distance, but with a few quality improvements, these lights could be excellent.

    Nice but not high quality

    Nice lights. Not high quality. Plastic is thin and pliable. They might last. Not much light emitted from these. They are more of a decorative feature than to provide light. They give off a nice ambience.

    Great lights, installation guide not so good

    These are really nice solar post cap lights. I had some that were installed at least 10 years ago before I bought my house, an old style, and these are such a huge upgrade. These light up the whole way around the light. While they are not meant to light up the whole area, they do provide an ambient glow which is welcoming and nice for your entryway. The old ones were really depleted, but also they just had one LED so I believe that even when new, they would have been very dim in comparison. I installed these myself and I am no expert. My posts are 3.5 x 3.5, making them just slightly loose during install, I just had to hold them in place during drilling, no impact on how it looks once installed. I drilled pilot holes, then there are just two screws in each of the cap lights. Took me maybe 15 minutes to figure it out. It would take someone with experience 5 minutes! Directions could have been better, step 1 and 2 were ok, step 3 says “complete installation steps (?). I looked up a youtube video.

    Great solar lights with replaceable solar batteries.

    I have two posts at the end of my gate that solar lights sit on. My current t set has about reached the end of there life. These are a nice replacement. Comes with everything you need including solar batteries that can be replace unlike my current set which is nice. I look forward to enjoying them for years to come. Recommend. Great value for the money.

    Fits My Vinyl 4x4 Post

    Fits either vinyl or wood 4x4 posts, adaptor included.The solar panel and battery are strong enough to keep the light on all night during midsummer daylight conditions. The battery is a 600 mAh AA nicad, easily sourced and easily replaced.The LEDs are bright, but not extremely so. They will light up your walkway, but just barely.The light is mainly plastic, not metal, which makes it more vulnerable to UV rays and weathering. But at its price point you usually don‘t get a metal light.
