UV isn't wasted, it increases tric production up to 20% , UV-B in particular works the best and MANY LED users are implementing a UV supplement. That's the main reason gavita suggests plasma supplementation, those suckers produce a ton of UV.
How the fuck do you figure that? You've clearly have never used COBs before. HIDs are way hotter than solid state lighting, and solid state is way easier to keep cool. My 89w Tasty Cree CXB3590 3500k puts out the PPFD of a 400-600w HID in a smaller 2x2 are. I use two to get my entire closet for less than 200w.
1000w of HPS = 1000w of COB = 1000w of a heater , all watts convert to BTU at the same rate.
i'm sorry, meant IR, not uv, i actually run a couple of reptile lights myself
Yea IR is kinda wasteful , I don't think it falls under the McCree chart and HPS lights make a good 10-20% Spectral Power in IR.i'm sorry, meant IR, not uv, i actually run a couple of reptile lights myself
No it isn't. At all. Plants don't read watts, they read PAR plus UV and IR. And like I said, solid state is no where near as hot as HID. HID wastes watts in unusable wavelengths, mostly converted into heat. I actually have to add a heater in my room because it gets too cold.
PAR has nothing at all to do with heat, 1000w of any energy source is the same as 1000w of another, you need to read up on physics. Read about the first law of thermodynamics and the law of conservation of energy.
You are down right stupid, touch has nothing to do with ambient heat and thermodynamics, please read up before you speak anymore. Furthermore HID stands for High Intensity Discharge....
Are you retarded? Where do you think the ambient heat comes from? Use a COB, then you can speak all the bullshit you want.
I been using COBs longer than you been growing , please read up before you speak you just make yourself look uneducated and ignorant.
Bro do you know anything about the laws of thermodynamics or are you once again talking about shit that is above you? Pains me to do this but you seem to have worked your way on to my ignore list now, thought we could get along but you are so uneducated and ignorant it isn't worth me even being bothered to explain more to you, go read up about Newtonian physics and the laws of thermodynamics or take a college course I think you got a lot to learn.
Unfortunately on here about this subject there is a lot of opinions with little help for those like us. I use a 400 w mh/hps and plan on switching over to LEDs asap. As far as I can tell the full spectrum whites are the way to go if you watch any utube check out growmau5 or greengenes channel they have a lot of info on leds, They are also on here or they were so maybe if you message them they might be able to help you out. Best of luck on your search.
heres the thing. if you have a 600 watt hps and replace it with an actual 600 watt led, it would be practically identical heat and energy use wise. the advantage is that you don't need a 600 watt led to replace a 600 watt hps, a good led with the right spectrum that actually uses 300 watts will be just as effective as a 600 watt hps. so it uses half the electricity and produces half the heat, while producing only the wavelengths of light that you want.
Your just plain wrong. Depending on what you put that 1000w into, will dictate what is produced. Saying 1000w put into any light source will create the same heat is wrong. I have a tad over 600w of leds in a 4x4, temps are 5 degrees above ambient temp and is 77, if i take all that down and put a 400w mh in there, it would be right about 85degrees. Why? Because hid is far less efficient at turning electricity into light and creates far more heat.
