What size fence posts do Brighticonic post cap lights fit?

Brighticonic post cap lights fit both 3x3 and 4x4 posts using the included adjustable bracket. The bracket adapts to either size, so one product covers both standard fence and deck post dimensions.

How long do solar post cap lights stay on at night?

The lights provide continuous illumination throughout the night on a full charge. They automatically turn on at dusk and off at dawn. The Ni-MH 1500mAh battery holds enough charge for 8-12 hours of operation.

Do post cap lights need direct sunlight to charge?

Direct sunlight provides the best charging, but the solar panels will charge on overcast days at reduced efficiency. For best performance, ensure the top of the post cap is not shaded by trees, overhangs, or structures.

Are solar post cap lights weatherproof?

Yes. Brighticonic post cap lights are designed for year-round outdoor use with waterproof construction and durable ABS plastic materials that resist UV degradation, rain, snow, and temperature extremes.

How many post cap lights do I need for my fence?

One light per post. For a standard 6-foot fence panel spacing, that means one light every 6-8 feet. A typical 100-foot fence line requires approximately 13-17 post cap lights. They come in 2-packs for cost savings.
