Re: QB288 v2 rspec help please.

So would the 320h-c2100b be a better option for the 3 boards then? Also, if I was to add a board... Would I be able to add a qb648? Can they be wired in series or parallel with the qb288 rspec? EDIT: I decided to follow the list of compatible drivers from ledgardeners video, I didnt catch it before,...

Re: QB288 v2 rspec help please.

Okay I'm getting it. So my decision for this is budget and ability to expand. I was only able to get 3 boards and heatsink. But I know I will be able to maybe grab another 2 boards and heatsink in a couple months. The idea was to have a driver that I could add those to, hence my choice of the 480. A...

Re: QB288 v2 rspec help please.

Yeah, i saw the driver was rated at 8.9amps which is just under the max for 3 boards which would be 9amps at 3000mA per board. But if I'm not mistaken the CV B type driver wont exceed its max of 8.9 or it would switch to CC. So I was thinking with that and added active cooling I could get optimal ef...

QB288 v2 rspec help please.

Hi all, I recently decided to make the switch to LEDs and decided to do it myself. This is going to be a couple questions also, just to clarify. So, I grabbed the slate2 triple and 3×qb288 v2 rspec boards from hlg. I had some trouble selecting a driver and still am not 100% sure of my choice. Which ...
