I bought 6 of these as a retrofit for work lights. Easy installation. Very bright. The spring clips are easy to remove (and reattach). They come with flange gaskets (unlike another brand I bought). I like that they are independent headlights (other brands grouped 4). Also note. Mount the box directly above the light source. This allows you to lower the light and service the box and connectors through the hole. So you don't have to crawl through the attic again for maintenance.
