LED can be very cool running, but high power LEDs are over driven, so they generate a lot of heat. They require heatsinks and cooling fans, otherwise they get burned out in seconds. On a per watt basis, LEDs produce more light than incandescent lights. Not as much as they claim, because they don't tell you the power inverter/supply/driver electronics also use up some power.

You should never use incandescent light for a greenhouse, even some manufacturers call those incandescent lights "grow lights"

That is because there is no such thing as LED TV screens. Also, BTW, there is no such thing as white LEDs.

Your dad is a scientist. He did not heat the doghouse with incandescent light. He was only heating the dog with incandescent IR light. Using infrared, you can get heated up in freezing air temperature. You can broil food with the oven door open, for instance.
