Modern LED Waterproof Solar Fence Deck Post Light

This die-cast aluminum post cap sits on fence posts or deck rails and runs two ways: hardwired to 110–220V or off a built-in polysilicon solar panel with battery backup. The 12W LED (3000K warm white, E27 socket) throws enough light to mark stairs or illuminate a walkway without washing out conversation on the deck. Solar mode needs six hours of direct sun to charge fully; hardwired mode gives you consistent output year-round.

Black powder-coat finish over spun aluminum holds up in salt air and summer storms. Sealed gasket around the lamp compartment keeps rain out of the socket. If you go solar, mount where the panel faces south and clears roof shadows. Hardwired installs pull from a standard junction box.

Works on 4×4 or 6×6 posts, garden pillars, or porch columns. Three sizes available: 11.8″, 15.7″, and 19.7″ square caps. Bulb is replaceable if you ever need to swap it. Cut power before maintenance.
