If your single board can handle 160 watts you should be good.

If it's a V2 board it requires a forward voltage of 50 - 54 volts. I doubt the 48 volt driver will work.

A V1 board I am not sure about.

There are chinese knockoff QB's that run on 48v.

Although it's not the best fit it should work. The driver has dimming capabilities in the built in pots.
Voltage adjustment range 43v - 54v
Current adjustment range 1.92 amps - 3.2 amps
So a V2 board run at 49.86v 2.8 Amps will give you 139.6 watts at the board.

As a side note I use a mw 120h 54a driver to power Samsung F strips, nominal voltage of 48v

Thank you so much for the thorough reply. Sounds like it will suit my needs just fine. Do you like your f strips? A little more affordable than boards is see

The F Strips are a great workhorse.
Yes, I just checked. 1 x QB 288 v2 £47
2 x Samsung F strips 288 diodes £39
The QB288 V1 IS $29 though. That Is cheap, such a bargain!

Just checked their site and saw for myself. I feel like a dummy now after cruising ebay and Amazon looking for deals. Good looking out. I think my plans for a 240w knock off have just changed. Thanks
