Nope,a thermometer a foot away from a CMH can get to 95 degrees,Doesnt mean my plants are 95 degrees,I like to place several thermometers and get the average temp of the room away from any radiant heat.But a good quality LED puts out enough of its own,Dude is posting numbers from a platinim LED that pulls about 400 watts from the wall and comparing to a 1000Watt HPS.there is just no comparison.every LED fixture is wattage dependant on how much heat they generate.I have a cheap ass
Mars Hydro 900 that was given to me for free as a tester model and it puts out nothing for heat,I would only compare that light to a 400W HID because the Mars pulls around 300 watts from the wall.
I would be willing to bet that 1000Watts of Cobs or QB's will put out almost as much radiant heat as a 1000W HPS but as far as ambiant heat they are almost identical.
A watt of electricity still generates around 3.4 BTU's of heat no matter what
