The K2TFFC is an excellent cool emitter with a very good average tint that is considerably warmer than most cool leds. However, while yours might indeed be just about as warm as a special warm emitter, others will probably be not quite that warm, and some will actually be quite close to what we'd call an unremarkable neutral white. They tend to be warm-er, but there's still variation and getting a specific tint is still not their top priority. A true warm emitter uses a special phosphor that gives up some efficiency (not a huge amount) in favor of a more pleasing tint than any "cool" emitter (that I've seen) is capable of. Although, that said, my M60WL is a little brighter than my T1 and has a very similar runtime; I think the K2 isn't exactly cutting edge in efficiency either. They're not at all bad either though.1) To avoid subjectively deciding which flashlight/pill *appears* "warmer," the sole criterion is the manufacturer's stated specification?
2) When I compare my Inova T1 and my Dereelight 5A Q3, they both seem "warmer" than my other lights. But the list is for those lights with emitters *specified* by the manufacturer as being warm...? Or is this incorrect. 😕
Just how close is your TFFC to a 5A? My T1 has a nice warm tint and was the best I'd ever seen.... until I compared it to a real warm emitter. The K2 has nice, strong reds and yellows, but they suddenly look very weak and ordinary next to a warmy.
