Aurora Deck Lighting’s newest addition to their outstanding lineup is the Neptune LED Post Cap Light. It’s a low-profile flat-top light that fits 4×4 wood posts, 4″, 4-1/2″ and 5″ post sleeves. Strong LED bulbs are built into all four corners of the heavy duty aluminum cap to shine downward. Choose from four versatile colours to blend in or stand out from your deck or fence posts.
