Nice to see more manufacturers using E21A. I will pass on this one because I don’t have use for mule, brightness decreases too quickly within a few meters without a reflector.
I have a D4v2 and KR4 16x E21A mule and see absolutely no tint shift. The only issue with those mules is the positioning of the emitter around the outer perimeter causes a whopping 20% output loss and narrows the beam. The positioning of the emitters at the center in the FF mule will resolve this huge issue. Also FF made the right decision to use white mcpcb unlike the KR4 mule with the red MCPCB. White is the most reflective and the color DOES make a difference in measured output.
With 21 emitter and the optimal configuration mentioned above, this should make a good amount more than the specified 5,000 lumens at startup, especially considering this uses 21700 instead of the 18650 in the 16x E21A mules.
If this can charge and be used at the same time, then it would make for the perfect table lamp. The E21A 9080’s light quality is better than any light bulb I’ve tested and I tested ALOT!!
I saw your post about the light loss previously and indeed here this is a much better design, but maybe that’s the reason you didn’t notice the tint shift ? since it’s cutting most the greener light.
For lightbulbs the best I’ve seen are Sunlike SOL basically perfect.
For me, I like duv a little below the BBL. It just feels so much more relaxed and welcoming. I’ve tested many lights with near perfect color rendering but lack the slightly rosy tint I like to see before bedtime.
