I have bought several of these 7w and 15w led bulbs. Exceptionally bright. I use three 7w work lights and they illuminate the entire work area (10ft x 12ft). I have tried other brands and this is the best value for money and I will definitely be buying more. Attention: Make sure the output power is at least 60W for 7W LED and 100W for 15W LED. Otherwise, the LED will flash on and off. I installed 15 watts in my ceiling which is only rated for 60 watts and the LED burned out the controller.
