Wheels got to turning on led diy builds and I’m looking at a qb setup in the neighborhood of of 1800-2200 total watts. Is there a noticeable difference in yield/quality between lm281b qb288(3500k ir uv) boards and the same color lm301b board?

I am testing spider farmer against dimgogo 1000 they both have meanwell drivers and the 3000 and 5000 samsung 301b’s, the spider farmer is pulling 104 watts wile the dimgogo’s are 110-120. Plants cant seem to tell the difference, been about 4 months now
the dimgogo’s were half the price of the spider farmer and came with a pair of sunglasses for leds
as far as diy what i see is it costs more and your useing the bridgelux(less intense leds). Nothing against those building there own.

I’ve looked, but the 281b boards are like $15/ea compared to $45-$60 for the 301b. Both are the same spectrum (3500k + uv + ir) damn, I think I just answered my own question 
a 20 lumen/watt difference isn’t big enough to justify the increased costs. Gonna get 20 of these hoes.
