I never mentioned "science", you did. I asked you nicely for it beforehand and you ignored the request.
Have you used led before?
Air-conditioning isn't a luxury i personally have. Went with hps myself after using led, because i was using extra watts to heat my space. Hps i don't, for the same amount of energy. Fyi it's still too hot most summer without aircon regardless.
Power is 37c/kwh for me, saves me hundreds a bill. If I was using aircon during summer, it would only add up to more.
Most LED's have a heat sink as well.
You make bold claims and mention science, so where is the data? Studies, watt for watt comparisons, temps, operating temperature, PAR output etc.
I have none of this, only what i've experienced first hand. So i'm politely asking you to show the science, because you made me curious when you mentioned it, and I thought i might learn something new.
Every grower's needs are different, light included.
