Depends what you mean by cool.
LEDs do not run *cold*, (at ambient temperature) but run at a low lower
temperature than incandescents, halogens etc, which in my book classes as
*cool*

They generally produce the same amount of heat for a given amount of
light - it's just spread out more.
And the LED junctions themselves have to remain at a moderately low
temperature (50C) to have a reasonable life in most cases.
