“I purchased this for the front of a 36-foot wide pole barn, above the sliding door. Although the light is very bright, I was surprised that the "cone" of coverage it provides is quite limited. It illuminates an area about 10 feet on either side of the fixture (fading in intensity at the edges). It does not cover the entire width of the barn front. I don't know if there would be another type of light that would have provided more coverage, but for the price I was hoping for something a bit more effective. It does come on right at dusk and seems to be well made.”
