These lights are very bright and really easy to install! The junction box not being attached to the light makes installation much easier. The light attaches to the power with a quick connection that twists a 1/4 turn after it's connected so you know it's secure. I installed these in my basement with no ceiling. I am leaving it open and painting it black. I used hanger straps that normally are for hanging hvac ductwork to attach them to the exposed floor joists. I attached them 6 inches apart and the flange that normally would go above your drop ceiling tile or drywall grabs the hanger straps securely. For power going into the driver box, I tried to use the push in connectors instead of wire nuts but the black and white wires weren't sturdy enough to work. I got a contractor pack of Wago lever nuts and those worked wonderfully. I have 4 that light an entire 14x13 room like the sun is shining in it. I went with 6 lights for a 16x14 room and it feels brighter than the 4 bulb fluorescent fixture that was there, and there are out of the way and hidden between the floor joists. The warm 3k color temperature is accurate so it doesn't look like a space ship is landing, like the cooler color temperatures. I love these lights and will definitely buy them again for my next project.
