After drilling 12 holes in ceiling to attach a Commercial Electric 4 x 1 LED mounting plate that hit vents/studs in both directions, I took it back and exchanged it for this wonderful light, which is half the price of the other light. This light was super easy to install, less than 20 minutes. With 20" diameter, it covers the holes I drilled for the other light (yay!). Mounting plate for this light attaches with 2 screws right to the junction box, so no holes to drill in ceiling. Nice and lightweight, dome is plastic and twists on/off easily (so it bugs get it and die, you can twist the dome off and clean it easily). Unless you're picky and don't like a plastic dome (dome seems to be pretty good quality, at least you wouldn't hurt yourself if you hit your head on it), you might really be happy with this light. I think it's pretty bright. Used this to replace an old fashioned fluorescent 4 x 1, and can't tell the difference in the amount of light from the fluorescent.
