Lit!
I’ve purchased a ton of these solar lights and finally got a set that lights every time and withstands the elements. We use these lights on our dock posts to light our paths after a night run. They’re not super bright light up the whole yard lights, but just enough to light your way and look appealing. They have a shut off switch and can be set to soft white or bright light.They are easy to install with just a few included screws and will first multiple sizes of posts.

They look high-end and are easy to install
These are well made, easy to install, and look high-end. They come with different size attachments depending on your post size. I prefer the warm light and it looks so nice at night. Because of the cost I only installed them on every other post along the short side of my fence and on the posts where my gates are located. They stay on all night. I highly recommend.

Nice lights
I had lights on my deck for years and they finally quit working, I had changed the batteries, and they still did not work so I felt it was time for new lights. I chose these because of the color change. These lights are bright and easy to install. Would have given 5 stars but the reflective part was a pain to get to stay where it belonged.

Light up the Stairway
The solar post caps work very well to help light up the stairway to our porch. The lights are bright, but not glaring. They add a bit class to the house along with other yard lights near the sidewalk. Recommended.

Worked as expected
Nice lights that fit onto my deck post perfectly and match my deck railing. Lights are modestly bright and last throughout the night.

Immediate, instant upgrade
We’re doing a lot of home repairs and upgrades at the moment and I wanted to focus not just on the inside but the outside of my house. The caps are stunning in person and add a much needed amount of light to the yard at night. They don’t blind you, but add that bit of ambience that makes our house feel more like a home. The mounting process couldn’t be easier and would be a cinch for even the most novice DIYers. The switch allows you to turn them On/Off/Choose which color light you want, opening up possibilities of alternating lights in the chain or turning them off entirely if you don’t want them to run every night. I’m a huge fan of “set it and forget it” type products, so this one was a no-brainer when buying. Also eliminates the need to run wire along the fence as you just use the free energy from the sun!

Worth the price!
Oh I love, love, love! Mad at myself for not buying this product the first time I saw it on Amazon because I saw one that was cheaper and bought that instead, which didn’t last long. So I ordered this just before the holidays and has been consistently efficient even on cloudy days.

Love the look. Quality not so much.
Plus: The light caps have a simple modern look which I like a lot.Minus: Only the soft white (yellow) setting works on one of the 6 lights and after 2 weeks another one died on both settings!
