Review on 4 Pack SIEDiNLAR Solar Post Cap Lights Outdoor 8 LEDs For 4X4 5X5 6X6 Fence Deck Patio Decoration With 2 Color Modes - Warm White & Cool White Lighting by Alan Sitton

Siedinlar Solar Post Cap Lights are easy to install - they come with different adapters and a set of screws. I installed these lights on 5x5 vinyl posts using one of the provided adapters. I did not use provided screws since they were generic metal screws which did not match white color of the posts and lights. In addition, they were too long for vinyl posts. I used instead short white hex screws used to secure gutters.The lights are not overly bright, however bright enough, especially when it is completely dark outside - comparable with similar lights from other vendors. Unfortunately the batteries in these light do not last very long. By 3:30AM-4AM the lights go dark.
