I also flashed a new 219B firmware to another light with all the new features (optional memory, 2 mode lockout, factory reset). Pretty cool. When my aux boards from Lexel get here i’ll play with that more.
Thanks! Wow… that’s some serious glow power. Does CRX have a topic where he gets into the details of what product he uses and the substrate? I’m thinking it might be worthwhile to paint the GITD paste over GITD tape, so it can be removed at some later point.
I received the two FW3A, standard dark gray aluminum and the copper. The copper is drop dead gorgeous! The finish is very shiny, almost mirror like. It is the most beautiful copper light I’ve seen yet. Below are my test results:
E07 SST-20 4000K FB4 tint bin for comparison:
CCT: 3822K
DUV: 0.0028
CRI: 93.7
R9: 76.5
Rf: 93
Rg: 101
The SST-20 4000k in the FW3A matches the FD2 tint bin. It looks much better than the widely used FB4 tint or 219C 90CRI and high output is almost as good as Cree 5A/5D tint.
For anyone interested, I think the Kaidomain quad mcpcb and quad optic would be a direct swap in to the FW3A. The Kaidomain quad optic is smaller diameter than the Carclo quad but larger than Carclo triple. However it has slightly smaller OD than the non-Carclo stock triple that Lumintop was using in the previous batch of FW3A.
Do you think this is the same optic Wuben and FireFlies used in their quads? If so I would liken it to something between narrow and medium beam width and lightly frosted in “Carclo” terms. It’s pretty good if you are not looking for overly throwy or overly floody.
Edit (stolen from Wuben thread, thanks Chatika vas Paus):
Yeah the Wuben/Fireflies quad optic is much wider than a Carclo triple.
The KD triple optics I have are very throwy, and have almost a clear, “empty” looking spot right in the center of each individual optic. You can clearly see the emitter with no distortion/magnification I can see through the center. They don’t seem as efficient Carclo ones though, but that could be the light going into the wider spill vs Carclo narrow spot maybe? Hard to tell by the naked eye.
