the energy either gets converted to heat directly, or it gets converted into light, and then into heat. either way, you get heat....
Yep
Doesn't translate to same grow room temperatures tho.
My grow room is basement so when the energy turns to light then the light hits the walls and floor and ceiling it's radiating in to cool concrete that dissipated more heat than any light I could have would. Because foundation goes in to other rooms and connects with the earth.
If I had a lesser efficient light it puts
More heat in to the air radiated from the resistance of the light thus directly heating the air.
So for my basement grow room temps can not be the same no matter what with 1000 watts of high and low efficiency lighting.
1000w Hid has roughly 700 watts heating the air and 300 radiating through my walls and foundation.
1000w Led at 60% has roughly 400watts heating the air and 600 watts radiating through my walls and foundation.
So end state is it really depends on the insulation of the grow room. A perfectly insulated grow room floor walls ceiling will have roughly the same heat of any light reguardless of efficiency. There is no perfect insulation tho so the more efficient light will always be somewhat cooler but maybe not much at all.
