N2Fg, I'm going to build a 175w light for a 1x1 space (head room no issue as such) and wanted to use 16 x cree 1512 3000k 93cri because they will run perfectly at 10w each, @18v will only require 1 x driver and will be 200w max for $200.
i cannot workout what the par would be of the light...
I don't have time to read the thread so apologies if unwanted info. I just saw a guy use a thin sheet of copper attached to a tube of copper underneath and use this as a supposedly very efficient, water cooled, heat sink.
Is this the ultimate light for a 1x1m space?
Headroom not an issue although I assume a light with small cobs wants to be closer to the canopy for light penetration?
So far it will give me just under 20,000 lux, 200w max power in 3000k 93cri for $200
I have also found a version using 3 step...
