Heybright 4" 9W 4000K recessed LED downlight on test. Use a fraction of the wattage for the same amount of light and much less heat. A few details for this particular one. The instructions give a round 4-3 /8" mounting hole and they fit at least 4-1/4" in a pinch. - The bracket mounts in material no thicker than 3/4" so the clips will fit properly. Drywall and false ceilings are usually 1/2" thick, so this is not a problem. A 3/4" thick kitchen blind will also work. Ceiling material. Junction box size is approximately 1-1/2" x 3-1/2" x 3- 3/4". It has a hinged lid that snaps into place without screws. And it has two 1/2" knockout holes for wiring. The cord between the junction box and the light is about 22 inches long, so the light can be a significant distance from the box. - When I checked the light, it got hot. up to 38 degrees Fahrenheit above ambient, and the power adapter in the junction box was only 15 degrees Fahrenheit. Unless you're using it in a very hot environment, it should stay within the specs for the LED chips. They are bright and have a format of 4 inches. Wonderful. I never want to go back to the old glow cans.
