Higher g/w are achievable under lower ppfd, as you increase ppfd the g/w will go down but yields will still increase. If high g/w are your goal you probably dont want to go over 600ppfd.

I'm in the process of getting another 1m2tent, I have my 55w diy autocob with 1212 clu0 , and I DONT KNOW WHAT TO ADD, DIY IS not a option, Tgl is off coz their autocobs raises tent temp by 3c+, so only 400e option I got Is telos.. Or If anyone have better idea..
Bro, 500W of light is 500W of heat.
If you want lower temps, you need less watts there. No matter if it's TGL, AC or Telos.
But with COBs you can get up to 30-31°C.
You can save a bit by keeping your drivers outside the tent. Also I suppose it wouldnt be too hard to create a vented cob light which would capture the waste heat produced and vent it outside the tent, like some HID fixtures do. You could cut heat by probably 40% that way but you would need fans, etc to push/pull air around.

Sorry dude but I lost you.. As far as i Know telos pulls out 250w and my cob is 55w.. So i cant understand what are u talking about?
And I dont know did you compare big smo auto cobs and tgl 60..They are not the same.. I'm limited to Eu sellers, and I dont have much options..
I have two options.. my cob plus this two cobs http://www.rubol.nl/product/rubol-josephine-plugplay/
or telos 0008 plus my cob.. Its the same price.. F....ck.. I only now see that telos is without VAT ?? wtf!!!
what kind of fuc*ery is that @GrowNorthern ??!!! prices without VAT??!!
What hes saying is that every watt of electricity you use in a tent IS heat, virtually. Of course some of the energy is used by the plant to create organic compounds, but its very small, enough to be negligible. So if you are using 300w telos, or 300w of cobs, or a 300w curling iron, they all produce the SAME amount of heat you need to deal with in some way or another.

But I never mentioned heat? I dont know why we are discussing this..my touts were should I buy telos and add my auto cob, or should I buy another 2 cobs and add my auto cob?? But telos price is advertised without VAT so only option is two of 3590 single cobs plus my single cobs...
You said TGL is not an option, because it rises temps by 3°C. But I doubt this, because my 220W light rises temp by only 4-5°C. As I know, TGL is 50-70W COB.
So if you looking into Telos which is 250W, that will generate 4x as much heat as TGL (4x 50-70W = 200-280W). So even worse for your situation.
