Works well as a replacement for my LED bulbs. Came with a similarly rated device, 100 watts. Uses 102W for 87W LED lighting. Voltage is at the same level with adjustment when needed (I haven't done this). It's gonna be hot, but I'm a little overrated. I installed a 1 inch fan and a resistor directed at it so that there would be a slight breeze and there would be no problems. The original that came with my lamp lasted about 2 weeks, this one far outlived it. Has a 2 second delay, it takes longer to turn on than the rest. You can see the other lights come on long before and they also have a delay. Otherwise it's great.
