Question: How many LED bulbs does one post cap contain? Lumens?
Document: Look - this is a post cap... not a floodlight! I am not sure what people expect, but it is a really nice accent light. Sure, it will not be enough light for a dinner party on my deck, but it is a nice accent light for the perimeter. Plus, this is the right price compared to  an entire low voltage kit.One thing to note - the batteries do take a few days to really charge.
The solar post cap lights are great. They were easy to install and worked just fine.They are very nice looking and would recommend them to anyone. The light is very bright from the 4 solar panels on top.
After testing a few other post-cap lights, my neighbor and I purchased enough for both our properties. The soft glow in our yards is just what we were after..The copper color, although plastic,sets an aire of quality that compliments our new fences.
I have had 2 of these Solar Post lamps for over a year, now. They give enough light and the  light given off lasts much longer than one would imagine. I will be ordering more of these to go with the ones I already have.
We purchased 10 of these and all of them worked and are still working 3 months later. They are perfect for our need. They are not high end post cap lights, but at $14.97 each, we were not expecting high end. They are quite a ways from the house. If you have an area - like a deck right off the house, you might want to spend a little more for a higher quality product.
My husband wanted a solar cap for our mail box. We live in an area that is very dark at night and he the post cap to provide a beacon for the entrance to our driveway. Super fast shipping and the cap was very easy to install. Worked perfectly and the fact that there are 4 places to capture the light make this a long lasting beacon. All the neighbors love it.
The description was misleading. Post sizes are already confusing, but I did find the difference between nominal 4x4 and actual 4x4 in different listings. This one says "fits any 4x4-inch post", but it was indeed too small for my actual 4x4. Sent them back.
They're about 5/8&#34; long, and the threaded portion goes about a half-inch deep from the head -- and one part of that half-inch is the plastic base, and another is the empty space between the base and the post. I replaced the mounting screws with other 1&#34; brass screws I had on hand.An on/off switch is mounted inside the light.
Ordered 4 of these lights for the gate posts. They all worked right out of the box and all four were beautiful. I love the look so much, I just ordered 6 more. I will have one on each post across the front of my house. Just one tiny thing, 2 of them look blue and 2 look green (lights when on.) Over all they are perfect. I'm so pleased. Thanks for a great product at a great price.
Very well built. Not very bright. Good value for the price. Wish it had a brighter or larger bulbs for more light.
