Here we go!!
I had this light laying around for quite some time. I used it a bit when I first got it but was disappointed with plant growth and coverage. It was filthy when I started but at the end of this project....well, you'll see!
Opened the thing up to see what I was working with.
Looks like we can use the small 12v fan driver so that's a keeper. I started disassembling the light while trying to figure out if I could use 1 of the 2 actual LED drivers in there. I decided not to because even though it is a 50-100v driver and we are using a 50 volt cob I want the option to run it really soft I need it to be able to run at a lower voltage around 45-46 as well. The driver also maxed out at 550-600mA so that wouldn't be good enough for the top end I want either.
So back to the tear down.
I decided I could actually use the aluminum LED board for a needed center plate. So when I removed the glass that was used as a perfect outline on where to cut the LED board to fit the place of the glass.
I used my soldering iron to remove and save all of the LED modules because that stuff always comes in handy.
I figured the fastest way to remove all of the diodes was to heat the stripped LED board with my heat gun and that let all of the diodes slide right off the board. After the board was cleaned of components I cut it to size and put it in place and folded the tabs down so it stays in it's new home.

That should give me decent power at 1.4 amps. Not quite 100 but plenty. As you can see to get the driver to fit in there and give enough room for the heat sink and cob to be centered I had to trim the tabs off the driver to get just a hair more room.
Drilled mounting holes and used Stainless hardware to secure the driver.

fanleaf;3205331 said:After that I centered the heatsink and cob and marked drill holes to be sure everything would be pretty neat.
Time to clean up rough edges
fanleaf;3205340 said:Now to put everything with the heatsink, fan and chip in its place I mark and drill the holes and then mount the chip using Arctic Silver 5 thermal paste.
fanleaf;3205344 said:Now to wire up the chip, fan to the little fan driver, and power plug and dimmer wires I always solder and heat shrink everything so it's safe and tidy.
