the Nightcore is a one cell light, no?
If they can get regulated 200 lumens OTF one primary cell, that would be something. Remember many import lights claim "225 lumens extreme tactical!!!!" when they are only putting out 90-150.
Ah the wonders of marketing.
It is indeed a 1 cell light, (was running it with an RCR123 though), but the Nitecore Extreme I believe has been tested OTF outputting a true 200+ lumens. In addition it gets rather hot if you leave it on too long. Also, I don't think the runtime is over one hour with a primary, as the LX2 is 2 hours. Comparison only for lumen check! lol
