Traditional Square Black Solar Post Cap Light

This square post cap light clamps onto 4×4 or 5×5 wood posts—fence lines, deck rails, driveway markers. Black powder-coated aluminum frame with a glass lens that doesn't yellow or crack the way acrylic does after a season of UV exposure. Choose hardwired (requires E27 bulb, 110V) or solar (built-in 5W LED array, no wiring).

The solar version charges during the day and switches on automatically at dusk, running up to 12 hours on a full charge. Toggle between 3000K warm white, 4500K neutral, or 6000K cool white using your existing light switch—you're adjusting color temperature, not brightness. The dual-use solar model can also accept hardwired power if you add a bulb and connect the wires later.

Sealed electronics handle rain and snow. At 7.3 inches square and 14 inches tall, it sits low-profile on standard posts. Works in yards, along driveways, or as pathway markers. Tool-free battery access when you need it.
