Square Black Modern Solar Outdoor Fence Post Light

This square post cap sits flush on 4x4 or 6x6 fence posts and throws warm white light down both sides of the rail line. Die-cast aluminum housing in matte black holds an acrylic diffuser that softens the LED without washing out. You get two power paths: hardwired (18W or 20W) if you're running low-voltage landscape wire, or solar (6W or 8W) with a built-in panel and dusk sensor if the post gets four hours of direct sun.

The smaller 9×9-inch cap covers standard 4x4 posts and lights roughly 54 square feet—enough for gate entries or deck corners. The 11×11-inch version fits 6x6 posts and pushes closer to 108 square feet, useful for long fence runs or driveway pillars. IP54 rating keeps rain and dust out; the acrylic lens won't yellow or crack through winter freeze cycles the way polycarbonate can.

Works on wood, composite, or masonry posts. Warm white at 3200K reads closer to incandescent than the blue-tinged LEDs common in budget solar caps. Hardwired models need 100–240V transformer; solar models charge during the day and auto-on at dusk. Hardware included for both mount types.
