Good choice

I ordered several to determine the best design and fit. The SL211W was the winner! it fit the post and looks great! However, they were install Jan 10 and I noticed last night Jan 15 that one was not on. I'll give it another day or two but may need to troubleshoot it. But all in all they are perfect for my new Trex deck.

The Caps that Fit

I am very pleased with the Imperial Solar Post Cap lights. They are the only ones that fit over my fence posts on my deck railings. Other brands fit flush to the post and cannot be used. The lights are bright and last a very long time and look very nice. I recommend this product.
