Perfect! by
We keep adding more of these to replace Trex black post caps. Very well built and engineered. They add the perfect touch to our deck posts. Given good sunlight conditions they last nearly all night.

Great but.... by
Great quality compared to others, but light on brighter setting does not last long... perhaps because it's November (less daylight) we'll see when the days get longer...

Installed a couple of days ago. Seem to be working just fine. Craftsmanship of lights seems good also. Easy to use. Would definitely recommend them at this point.

Quality cap and light by
We are very impressed with both the quality of the postcap and the light produced. It matches the look of our other Trex black caps and the light color matches the 27k of the Kichler hammered bronze post lights we have. We will be adding several more around...

We have been looking for solar caps that look good and work well for our Trex deck. Trex did not have anything As they want to sell you a wired solution. Installation was simple and quick.
