Ok, So it seems that LEDS waste about 70% of the energy that they consume
and that energy becomes heat.

Unless they are IR LEDs

In so much that the typical LED, and all of the ones I have purchased, use
10% or much less energy than a comparable incandescent light I have not
witnessed any heat at all. My sampling has included 3-4 ribbons of LEDs,
multiple strings of LED Christmas lights all plugged into each other, and a
couple of out door 60 watt incandescent coach lights replaced with
equivalency light out put LED bulbs. The biggest consumers of electricity
of this sampling is 7 watts and even those might only be producing about
1/3 the amount of heat of a typical 7 watt incandescent light bulb.


Show me a single LED that consumed 180 watts by itself and I think it, the
LED itself and not the transformer or other involved electronics, will get
hot enough to equal a common 60 watt incandescent light bulb.
