Question: How does it install?
Document: These are attractive, were easy to install, and the light shines better than I expected. Purchased five and will purchase more.
They work very nicely, I am completely satisfied.They were easy to install. I like the easy access to the batteries.
It is great. Very easy to install with the pre-installed rechargeable battery. It turns on and off by itself everyday automatically. Low maintenance.
These are super easy to install, flexible in sizing, and the lighting is brighter than other solar lights I have purchased . They look expensive but were not....a great purchase!
These solar lights are wonderful. Super easy to install, it took me longer to unpack them. It would have been nice if all the boxes had the screws included but no big deal they are just tiny wood screws
The light lasts over 6 hours at least (I don't stay up to find out). They were easy to install and give off enough light to see where I am walking at night on the back deck.
The LED fence post cap lights look great and were perfect for the dark areas next to my house. Each cap took less than two minutes to install and came on the first night.
I have had this about 2 months. stays lit most of the night and is very bright. looks great. easy to install, but i used extra screws (not supplied) to attach it more securely to the post. If you just put it in place with the screws provided, it could be knocked off the base too easily.
Even if I had decided to keep it and install in the spring, I would have had to take out the batteries to turn it off until then. Screws are difficult to unscrew because of placement and the cheapness of the plastic they screw into. I imagine that if you took this apart more than a few times, you would not be able to tighten the screws at all.I am disappointed!
I purchased 5 of these fence post cap lights for our new deck. I was hesitant at first, having purchased solar garden lights (from different manufacturer)that weren't bright enough.However, these post cap lights very easy to install (removed existing cap/replaced w/cap light! )and instant light! !
