We have a few ceiling fans at home with an enclosed lighting. There's a sticker inside it saying 2X20W max, CFL lights only. What is the reason they are restricted to CFL light only? I tried putting some LED lights on it and it seems to work fine (10.5W and 9W LED lights). The base of the LED lights is significantly hotter but everything else seems to be same temperature as CFL lights. Am i doing something wrong if i put LED lights with the "CFL only" restriction?
