DIY with Quantum Boards

I should have bought the pre assembled board, but then, how would I learn if I don't do it for myself? And every assembly that I've seen is not for the qb288... Go figure... And it sucks that I'm color blind... For real...

Running a 288 with the driver at max will produce a decent amount of heat, but most of it is coming off of the driver so as long as you have your extraction port at the top of the space a good deal of it will be vented before it has a chance to affect your canopy temps very much. Also, due to the QBs lack of IR most plants actually seem to like a higher ambient temp than they do with HPS or MH.

These light looks to be very good, i think if i use quantum board i can have 400 gram from 400 watt of this light. I plan to use hps on my first grow but i see these light have double lumens from hps mean if i am lucky i can have double yield if i order this light. Is this how this lights work that you can have double yield from hps?
I have bad eyes and cant see all text but i see this is a good light

It puts out less heat At the board than many light, depending as for all, how much power you put to it. This is what efficiency stats tell you. An HPS that is 35% efficient generates 65% waste heat, and 35% light. Lets say you run your QB at mid power. 50% heat/50% light.

The last thing you need to understand is 185 watts of power, eventually creates 185 watts of heat, as light striking an object ( like your plants ) converts its energy to heat. However, its that concentrated heat emitted at the light that creates the most issues and the need for good ventilation. QB's are among the most efficient garden lights you can buy. And that efficiency statistic tell you why LED is taking over, you get many more photons per watt compared to any other light source.
