I've just choosed a 24v driver with enough drive current for 1, 2, 4 or 6 QB18's. These Meanwell CV/CC drivers are available from HLG-40 to HLG-600w and from 12 to 54v. The CC only version from HLG-60 to HLG-600 so its pretty easy to find a siutable one.
Just divide the maximum wattage by 24v and you know how much current the driver has. 80w : 24v is 3,33 so an HLG-80H-24 should have 3,3 or 3,35A. Enough for 2 strips in parallel...
150w : 24v means 6,25A, enough to drive 3 QB18's in parallel at 2,083A which is close to the maximum. So to max out 3 QB18's an HLG-150H-24A or B would be the best fit.
Unfortunately there is no HLG-50 that fits perfect with a single strip so we have to look for the next siutable driver.
