Teacher, there is a difference in tint between the 70 CRI W6 power bin and the 80 CRI U6 power bin… I find the W6 to be a nice smooth white and noticeably brighter. The U6 is a bit off in color, in spite of the higher CRI rating. Just this morning I built a quad X6 using the Noctigon 32mm MCPCB and Angie optic (Emisar D4S) and the output was too much a lemony color, but one piece of Lee minus one eighth filter does wonders! :slight_smile:

Essentially, C mixed tints to get approx where this one is now, and the look is really neat too! Nice catch, enjoy!
