Good news: the CCT of SBT90.2 in my Wurkkos TS30S is ~5200K. The beam of SBT90.2 will surprise a lot of people. For a super thrower it is suprisingly warm. Golden yellow slightly green, like the color of the LED itself. The only other thrower that has similar warm beam is Olight M2R Pro Warrior XHP35 HI, which is around 4700K. Very pleasant, except the green here could be a touch much depending on LED lottery (I have 3, all different colors). Although green tint doesn’t bother me as much in throwers - subjects being so far away.
The other two throwers that I have, Sofirn IF22a ~6400K (w/ SFT40) and Nitecore MH12S ~5900K (SST40) both have steely harsh blue beam that obliterates colors. Stay away from those 2 if that would bother you. In addition stay away from IF22a unless you are looking for a very narrow beam with hardly any spill, as a result of the 5 Degree TIR used. For me that kind of beam is unbalanced and the light therefore not my favorite, but of course that’s strictly personal preference.
Wurkkos TS30S will obliterate M21E and IF22a both in brightness and in usefulness of beam (wide, bright beam). IMHO the only competition for a SBT90.2 light is another SBT90.2 light. I looked at Convoy L8 but didn’t go for it because it is getting too large, costs twice as much, and uses that 26800 battery (I wanted to stay with 27100). Larger reflectors tend to create tighter smaller brighter hotspot (better throw) but may sacrifice spill (less flood). In retrospect I love the hotspot/spill balance of the Wurkkos so Convoy may not be an “upgrade” outside of throw. Hope this helps and sorry way OT to discuss Luminus and Cree in a Nichia thread lol.
