What are your thoughts on the spectrum?
How come your surprised more people don’t use them?
I’m a Bridgelux guy. Just curious.

Hey Hydrofood,
Just based on a rudimentary calculation and whats available from digi key. Using the same driver as OP, and doing calculations on lumens per $ cost. I might need to adjust my perspective here, as I made these calculations based on current knowledge, but am no expert and probably left out some other variable.
I currently run F-Series gen3 23v in two 6s separate series with hlg-185h-c1400b's, but have a surplus of the same drivers and want to build another set up with dedicated color temperatures (for my F series build, I went with equal number of all four temps - which has worked very well, no complaints). So I was looking at originally at a EBgen2 build, but the Lum/$ amount is the lowest, with the lowest total system lumens, BUT they have manufacturer posted spectrum. I have no problems with the Samsung diodes, and know first hand they work but I don't understand why they don't release that information. (perhaps I am short sighted and not considering business). Q-series were ruled out as the Lum/$ does not make sense right now, esepecially if the H inFlux use the same LM301B's.
Bridgelux also has cheapness and coverage (more strips) as quality's when comparing what is available right now. Why do you prefer bridgelux (if you have a hard or soft preference even) out of curiosity?
As for numbers with the HLG-185H-C1400B, I came up with:
14 EBgen2 2ft strips 7s2p @ $149.24 CAD (not including Canadian GST) - Total lumens 34398 @ 191.1watts @ 230.49Lum/$
28 EBgen2 1ft strips 7s4p @ $175.00 CAD (not including Canadian GST) - Total lumens 34398 @ 191.1watts @ 196.56Lum/$
3 F-Gen3 46v 2ft strips 3s0p @ $131.22 CAD (not including Canadian GST) - Total lumens 34969.2 @ 193.2watts @ 266.49Lum/$
3 H inFlux 44.6v 2ft strips 3s0p @ $140.85 CAD (not including Canadian GST) - Total lumens 35965.44 @ 187.32watts @ 255.35Lum/$
Other possibility would be to build the same same 2ft fseries gen3 build I already have, but where is the fun in that
6 F-Gen3 23v 2ft strips 6s0p @ $143.58 CAD (not including Canadian GST) - Total lumens 34969.2 @ 193.2watts @ 243.55Lum/$
Let me know what you think. Did I work this out right?
Cheers,
technically the 320 driver is more efficient ( 94% compared to 91%) but then, if something ever did happen to one of the 120's, you would still have some light until you could get it fixed/replaced.. just a single 320 goes, your out of luck until you can fix it. 
and oddly enough, I'm looking at h influx right now as well for another build. I am surprised that more people aren't using these. I wonder about the spectrum...
