I look forward to seeing your results. I plan on ordering at least 3 more once the SST-20s come around, but reports of gritty switches has me concerned.
Is the SST-20 really green at low levels? Seems like aside from makku's test nobody else claims it was greenish. I don't see how the LH351D is green either.
Typically, yes, the SST-20 and LH351D tend to have positive duv at low power levelsā¦ but the tint gets colder and the duv goes down at higher power levels.
If that doesnāt make sense, duv is the delta u-v on a tint graph, or the distance from the āpure whiteā blackbody locus line (BBL). Positive duv looks more green or yellowā¦ while negative duv tends to look more purple or pink.
In general, most people prefer somewhat pink tints. So those are what we generally aim for. But itās difficult to get pink-biased LEDsā¦ especially when looking for high-power LEDs which will often be used at low power levels. LED companies spec their lights at full power, not at the low levels often used in a flashlight.
For example, the SST-20 FA3 tint is approximately at the same place on that graph as the Cree 5A1 binā¦ so it should be pretty pink. But when itās running at low power, it still has a positive duv, closer to 5B4 on the graph above. And when itās running closer to full power, the tint is actually where the specs say it should be, and it looks nicely rose-tinted.
So SST-20 isnāt recommended for people who have a strong preference for rosy tint and plan to use the lights primarily at low power levels. But itās fine for people who use mostly brighter modes or who donāt care so much about the duv.
The FW3A unanodized (Ti/Cu ?) looks much better even less polished because a buffing wheel rounds off all those angles, rounded angles donāt look good to me.

Mine is getting BUFFED UP to a Mirror finish. In case I need to check my Grill or Comb my wigā¦.
The description says:
āCree XP-L HI 3D(NW 5000K) and Cree XP-L HI 7A(WW 3300K) LED
Cree XP-L HI 1A(CW 6500K)ā
so when selecting the tint, this is what they would send out.
Not every tint/LED is available, if you canāt put it into the basket, the item is sold out (like the Nichia currently?)
