The highest spec’ed R9050 B-V1 is D240, so that one should sit in between the B-V1 and C you’ve tested, output-wise. But then, first you’d have to find some…
I think I can confirm that the emitters in those Jaxman lights are NVSx219B-V1, indeed. They sent me a few LEDs. I thought I’d have to mount and test them for low Vf to confirm it, but a nice and clever member of TLF found a way to tell apart bare 219B’s and 219B-V1’s (thanks again Megalodon). Should I spoil it or give you guys some time to find out for yourselves?
They are totally different in appearance, so you don’t need to distinguish them from their solder pads. A and B also looks quite different. It’s just the B and B-V1 that look very similar apart from the solder pads.
I hope this isn’t a longshot, but does anyone have some solid beamshots of the “Nichia NVSL219BT-V1 4000K, 93 CRI, D200 Bin” versus the 219C that RMM carries?
I realize this is asking for 4000K vs. 5000K beamshots, but I’m trying to decide on what to get in a triple
I do not have those comparison beamshots, but I think the beam shape of the 219b v1 and 219c will not be very different, so a beamshot will not capture the difference. What is different is the output (the higher the current, the bigger the difference), and the colour reproduction, both is difficult to catch in a picture.
