    Default Informal CMG Infinity runtime test (Green LED model)

    I figured that since i have a pile of partially depleted AA cells, i should do a runtime test on the original long-runtime light, the CMG Infinity, the original Non-Ultra model with a green LED....

    I grabbed a AA cell that volt tested at 1.4V, and ZTS'ed at 80%, dropped it in the light and twisted the head to "on"

    that was *THREE* days ago, 72 hours of continuous runtime, it dropped below 50% brightness sometime during the day today, it's now no longer a vivid Blue-Green, it's just green, still producing usable light though, even though the battery meters .85V

    quite impressive that it's able to produce usable light well below the one volt level, i'd hazard a guess that i have about 2 more days of usable continuous light before it drops below a usable level

    72+ hours of runtime on a partially drained cell, quite good, really

    Look where he lives...

    (I have this light, and it is worth cheering about)

    Okay, i guess i was wrong about the number of days left, the Infinity is struggling to make usable light from the depleted battery now, as of 9:20 AM 4/14/07, i'd call it dead

    final battery voltage; .75V

    Yeah, that's pretty impressive. One of these days I'll get the courage to open up one of my non-Ultra Infinities and put a Snow 29 LED in there. And polish the 'reflector'.

    indeed....

    I have a similar expereince when I used an infinity Ultra to drain a AA battery...After a nightsleep I gave up....

    enjoy, kostas

    and indeed that light is robust enough to BEG for an upgrade....
