Another thing to keep in mind when choosing between these LEDs is the beam pattern. XML is generally more floody and has a much larger hotspot than 219s. I prefer flood in an EDC light so I used some diffuser film over the lens of my Eagletac D25C with the nichia emitter to get rid of the...
Has anybody heard anything from Eagletac regarding multi mode drop ins? These are a great value but I have no need for a 1000+ lumen single mode, I'd order multiples if they were 3-4 mode.
I have an XM-L2 D25C, can anyone tell me how much of a perceived difference there is in light output between the 219 and XML? Im guessing high on the 219 is similar to medium on the XML....?
