I have two rooms that i did same thing with...I installed 3 lithonia downlight 4" LED potlights in each room- with one lutron maestro C-L 153 MH dimmer in each room. After a week one maestro has completely died...No green lights on it - at all. To trouble shoot I swapped one lutron for the other...and another maestro the one is still completely dead. What happened?? Can i return it...but will a new one die the same way- after a week?? thanks!
