am i correct in assuming that its because sbt has a high drain? while all other emitters, including osram, are sufficiently handled by 10A discharge? does this make sbt run time less?
and also, it seems sbt advantage is high lumen? but whats the point of high lumen in a dedicated thrower? isnt kcd more important? the osram 2.1 having 650kcd will still have higher beam intensity, aka look brighter, than the sbt, no? sorry im still very new, just gathering pieces of information trying to put them together.
Noctigon K1 with SBT-90.2 can use FET turbo, while other emitters can only use regulated mode up to 5A or 7.5A max current.
SBT-90.2 has a much bigger hotspot, but because it can put out more lumens it also has very good throw. Other emitters have very good throw, but the hotspot is much smaller.
Great news, flooders or throwers? I still look for something what would keep high lumen flood on bike night rides better than Emisar D4s. Emisar lasts longest time when outside temp ist about 8*C.
