You have two different efficiencies listed for the cxa 3070 in post 54 and 59.
Which one is your correct estimation based on your extrapolation?
I ask because I am ready to order my modules. If the efficiency is really that high at 350 ma I will run 32 on meanwell hlg .7s (.35 to .77 adjustable). If it is only marginally better as per the first excel capture, then I will run 20 modules on meanwell hlg 1.05s (.525 to 1.07 adjustable). I already have a pretty big gain in efficiency using the hlgs at 92%+, vs individual drivers at about 85%. I think given this I can lose a couple % from the COBs and keep the BOM down.
Still haven't dialed in the ratio, but will likely be 6:2 at .7 (4 groups of
or 4:1 at 1.05 (4 groups of 5).
Appreciate it!
