The SST-20 in TK’s photos looks very green. I’ve never seen one that looks that bad, though they certainly don’t look good next to the 219B sw45k I have in my FW3A.
Tint beamshots are hard. Cameras capture colors differently, automatically post-process colors differently unless the photographer shoots in raw and does it manually, and displays display them differently. When I tried to get beamshots of the Armytek Prime XHP35, which is very rosy according to maukka’s testing, it just looked neutral. The beamshot in maukka’s review looks a little rosy, but doesn’t really capture it.
Anyway, I wouldn’t like SST-20s my eyes see the way TK’s camera does, but the FB4s I have don’t look nearly that bad. The FA3 supposedly being offered for the FW3A should be considerably better. I have FD2s on the way, and I have some Lee 801 minus green, which makes FB4 look great. Filters are a lot easier than sourcing emitters with nice tint the way the LED market is going lately.
