Thread: new p20c2 mII xm-l best lion battery option?

  1. #1

    Default new p20c2 mII xm-l best lion battery option?

    first this light puts out a wall of light. because of sheer brightness it does throw somewhat. I can't wait for a selfbuilt review.

    I assume that a 17670 lion would be the best for runtime so 2 rcrs would not have an advantage in brightness because the light uses a buck circuit?

    disregard this posting I didn't know my last posting went through. I had trouble with server last night.

    That is correct more volts through the same driver generally means more light. ref. aa vs. 14500

    huh?
    assuming of course the AA light can handle a 14500 otherwise you have

    The P20C2 is a CR123 based light that can handle up to 9volts...
    AFAIK any voltage above 4.2v is burned off as heat...
    2xCR123 = 6v
    2xR123/16340 = 8.4v
    1x17650 = 4.2v

    The new ET 720 Lumen HO modules run slightly less bright on 4.2v than they do at 6+v (6v or 8.4v shows no output difference when I measure with AEMC CA813 light meter, but light does get hotter quicker)

    The primary advantage of using 17670 over R123/16340 is 2-3x runtime...

    Cheers

    If I were to get the s2 module would the throw be any better? I have the scorpion v2 which actually throws very well for a small head. I guess now with the emitters getting larger the days of pocket throwers are gone.

    yes, the S2 has a bit more LUX than the XM-L in these small reflectors.

    720 lumens with large center spot XM-L has least amount of LUX
    vs
    500 lumens with smaller brighter center spot with S2 has almost same LUX as XR-E R2

    Cheers
