GreenLighting Modern Solar Post Cap Lights Fits 4x4 Wood, 4x4 & 5x5 PCV/Vinyl Outdoor Solar Powered Light, Fence Post, Landscaping, Deck, Garden- Bright LED, Waterproof Black 12 Pack

The ones we had on our deck when it was installed quit working so we bought these to replace them. They are decorative & put out a nice light at night.

I like the product. Good value

I love these but after about 3 years they turn yellow.

Easily installed, covered my 4x4 plastic covered posts perfectly. Maintain brightness for long period overnight in spring, probably last all night during summer sun charging. Good value.

Good for the price

I’ve had these lights for 3 years. The first year they were gorgeous! However, they discolored quickly from bright white to yellow. As other reviews have noted, the discoloration is a stark difference sitting atop the bright white porch post vinyl covering. Still, when it matters the most (at night), I didn’t let that be enough to write a bad post. By year 2, the battery contacts need constant hand-holding to ensure the two little lights remain as bright as possible. By hand holding I mean opening the top and turning the battery. Yes - I’m obsessive in also cleaning the contacts. Now- year three - I have two caps that aren’t working at all. I’ve tried everything. Replacement caps would be fine, but no such thing exists. So my decision point now is to scrap my entire 10 (remove the entire receptacle form each post) starting over. I’d almost be ‘ok’ with two new entire sets, but the difference in color to the others would be glaring. I’m glad now I did not permanently screw these onto my posts, rather I used two sided tape which has worked well over 3 years through 4 distinct seasons in Ohio. My photo shows a beautiful scene - but they are a pain in the neck over time!UPDATE: My Dad helped me repair my two inoperable tops by soldering the wire connectors that had become corroded inside the units. Lesson learned for me is to remove the tops every winter, and somehow cover each base for protection . Going to try that for a few years to see if I can extend the investment. My dad also indicated he will paint them white to cover the discoloration.

Love the lights looks very good

This did not fit at all the way I thought it would. My larger caps are 5 inches across and sit outside and on top of the post. These lights come with adapters, but for a 5 inch post they expect you to be able to take the adapter off and stick the smaller part of the light inside the post. Problem with that is there’s wooden posts inside the vinyl Post so it blocks them from sitting inside. Then for the smaller posts like on the gates, you have to use an adapter that makes it wider so you could sit it outside of those posts. Problem with that is that if you wanted to use them on a gate door, the doors will now not close because you put a wider cap on the outside of the post. They should’ve designed these the other way around! The small ends should fit inside a 4 inch post and then there should be an adapter to make them sit on top of the outside of a 5 inch post. Then on top of that what they don’t tell you in the description is that the way to secure these is they expect you to drill holes into your vinyl fence and then put screws through it into the light. They do not fit snugly, they just sit very loosely on top. So unless you plan on drilling holes in all of the fence posts this product is a waste of money.
