It has a smaller die than a 519a, but seems like it isn’t as bright or has as high of a maximum current (Also lower performance than a 219C).
Probably a better choice for low output and low-capacity lights to have a more useful beam profile, but I would prefer to use a 219C in 5000k high-cri and a medium-profile beam in a smaller light, as it doesn’t have the same issue of being a low max current. More 5700k R9080 options are always nice though, even if the DUV is slightly green.
Edit: Just realized the 219F that djozz tested is the original, @Simon_Mao do you have the original or the 219F-V1 or v2?
I recently received a few Convoy lights with GT FC40 and I’m totally in love with that emitter. The colors pop even better than Nichia 519A to my eye (although both are fantastic).
Simon, I’ve just noticed the S2+ Ti was released. But no stonewash version, are you gonna release a stonewash version and metal button too?
Also, when are the buck driver and 18350 tube gonna be available?
Simon, thank you for finally releasing the Ti S2+. im glad my pestering finally paid off I was the second order, I’ve been religiously checking for the release!
