This drop ceiling recessed can offers lumen adjusment and works for retrofits as well as new constructions. With 1530 to 3400 lumens of adjustable CCT white light and a 0-10V dimmer driver for 100-1% flicker-free dimming, it's the bee's knees! The integrated aluminum heat shink helps keep the LED module chill - so it'll perform for a looooong time.
