Perfect Finishing Touch!! by
This was the perfect finishing touch for our Azek Railing. It provides great light and a sophisticated appearance. Although not the cheapest, it was worth the investment. Additionally, the place looked amazing for our son's backyard wedding!!!

Quick delivery and nice people! by
I love the solar lights on our deck. They create a great ambiance, with enough light but not so bright that you want them off! Ultra Bright service was great. We had one that needed a battery and they got it out the next day. Quick delivery and nice people!

Wonderful Investment! by
It's only been a couple of days, but so far, we are extremely pleased with these post caps. Considering the cost, I was hesitant to purchase 12 of them, but I'm happy I did.

Installation is fairly simple, and the hardest part is securing the cap on some of the fatter...

Great cust svc, quick delivery, easy to follow instructions. These lights don’t just illuminate, they broadcast light. With multiple power/brightness settings, I’m able to pick how much light v. offsetting solar charged battery power needed.

Works very well, day after day, week after week, dusk to dawn, come rain or sun. We have two light caps mounted on posts adjacent to our front steps, and these lights are both functional and aesthetically appealing.
