Here is a 3 bulb security light I picked up from the scrap yard for almost nothing.
It had 1 working 100 watt bulb so I went to lowes and picked up a 20 watt bulb and three 2.3 watt LED (20 watt replacement).
The motion sensor on this light assembly was bad, maybe fried because someone put 3x100w bulbs in it when I believe it was only meant for 3x20watt bulbs.
That is fine because I wanted to put it on a switch and use it as an out side work light
The 100 watt bulb puts out an over whelming amount of light and heat compared to the other two "20 watt bulbs"
The LED actually appeared brighter and to put off more light than its 20 watt incandescent counterpart.
The 100w T8 loaded fixtures appear to be quite well equipped to de-ice them selves.
