Galaxyhydro 300w to 3950 conversion - Have questions

[hempofthedead]

Hey guys, inspired by other threads on this forum I have attempted to convert a mediocre blurble GH led into a nice dimmable cree build... the unit had 3 60-90 volt 500ma drivers in them, so i initially ordered three 72 volt 3590 chips.. fanleaf made me realize this wouldnt be quite the light i was hoping for, and ultimately now the new plan is two 72 volt chips powered by a 250h-1050b driver for hopefully a ~140-150 watt max light.. ultimately there wasnt good space to put the third one inside..

originally wanted to mount to the original plate, but did not end up being an option.. heatsink bars from HS-usa seemed too tall for the unit.. so ultimately landed on using two cpu coolers. pics below of where i'm at.. mounted up and on to wiring!

question for you other diyers: the unit has a switch.. from it are a series of wired that were plugged into the other drivers.. can i simply wire the ac side of the meanwell driver to one set of these white/black wires?

thanks

anyone have advice on wiring up the AC side to the meanwell? can i simply hook up the live and neutral part of the meanwell to the black/white wires on the bottom right? if so, what do i do with the ground? the cheap drivers in here only had 2 wires (no ground?)

thanks

Hey guys, figured it out... i removed the daisy chain plug and wired the driver to those wires (switch only for fans now), and used the space for the potentiometer. had to mount the driver to the outside. pulls from 25-180 watts and is bright as the sun..

thanks everyone for the inspiration and help.. especially fanleaf.. peace

cool.. i have since wired one of the original heatsinks over the middle area to prevent the fans from blowing hot hair down onto the plants
