Solar decklighting for my 6x6 fence posts . I found the best selection of solar lighting for my fence post lighting project was here under my nose . These come in so many sizes from 2 inch to 2 1/2 in. and 3 inch for my aluminum fence jobs to 3 1/2 in. , 5 inch and 5 1/2 inch for my wood deck and fence posts to also cover all of my vinyl posts and vinyl sleeves along with the new composite posts and sleeve on the deck and fence market today used on a lot of decks with solar lighting as a first choice option as there is less labor, they run for free, provide so much more efficient lighting and last !! These all carry a 5 yr warranty best on the market !!
