A MeanWell HLG-320H-48A(6,7Amps) and six Samsung 4ft. double row F-Series strips(nom. 2240mA, 48$ each) in parallel(6x 288 LM561c/S6).
The strips would run at half current(~1116mA) and effiency goes up to above 184lm/w(2,7μMol/J), ~310-330w total.
You can do it with 3 of these double row stripes as well, then they run with nom. current and you get about 168lm/w.(2.4μMol/J), 320-340w.
Each of these 4ft. DR strips equals a QB288, only longer and narrower! But that's even an advantage, because you can distribute the light even better, the 1120mm long strips fit perfectly in a 4 'wide tent.
You can take the single row strips as well but you need twice as much.
The shorter ones are also suitable as vertical sidelights...
You can get the stripes from digikey or arrow and the driver can be found at mousser.(search by part-no.)
This are the 4ft. DR strips in 3000°k(good all-in-one spectrum), 48$:

This are all currently available F-Series strips:

Ach, and do not worry about delivery times, the new strips will be delivered pretty quickly.
If you still prefer Bridgelux gen.2 take 10 of 4ft. strips and use an HLG-320H-42A. Each strip would run with ~670mA, which means ~176lm/w, ~280-300w at the wall.
