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.
Well, I just checked an 60 W equivalent LED in the kitchen and it gets
warm around the base. However, when I found a 60 W incandescent it
didn't take but about a minute to get too hot to touch. Checking the
card a replacement in the drawer is on it says that the 60 W equivalent
LED uses 9.5 W. So the answer to the original question, whether LEDs
produce heat, is yes. But they produce much less heat than
incandescents. I don't expect that a small LED would produce enough heat
to be easily detectable by hand.
LOL.. which is why I mentioned that If my fingers feel no heat at all
there for the most part the LEDs that I have used produce no appreciable
I measure heat this way. I feel nothing, I feel a little warmth, I feel
something hot that I don't want to touch.
The 7 watt single bulbs get a little warm where the ballast/transformer
is located near the screw in base but the bulb itself only gets warm
when the sun shines on it. I leave these lights on 24/7 also.
Well, I can tell you a 60 watt LED array produces enough (radiant)
heat that you can feel it 5 feet away. (LED aircraft landing / taxi
lighting). 10 WATTS PRODUCES ABOUT 30000 CANDELLA AND 1000 LUMENS.
So imagine 60 watts!!!!!!!
