    Default Gemini Lights Xera 800 lumen single 18650 flashlight/bikelight

    Didn't see anything here posted about this light so I thought people might be interested to have a look and see what they think.

    Before you scoff at the price look at the "what comes in the box" and it's not so bad + the excellent Panasonic 3100mAh battery and a charger.

    3.1 Ah x 3.7V / 1.5 hrs / ~3.2Vf = ~2400 mA (not yet accounting for driver losses)

    So 800 lumen is probably the top end of the U2 bin at that current, not yet accounting for optics losses either.

    U2s are only available in cool white, with low CRI (65).

    There's minimal heatsinking/finning so not sure how well it would handle extended running (ie as a bike light).

    Looks stylish and solid though, different optics are nice if you need them (though a proper bike beam pattern would be better)

    Yeah, it's so new I haven't seen any reviews on MTBR where I spend way to much time. Probably better as a mtn. bike light vs road as there is no cutoff but still effective none the less. They already have a new improved mount for it that just came out.

    I can personally vouch for their standard Xera helmet light which is just amazing and tiny. Mine is the pre U2 so the new ones are a bit better even I guess. Many happy users with this light.

    as to heatsinking / no finning ...
    thats a PLUS, as it makes for a non-edgy-cutty but sleek looking light
    (edges and teeth and such are totally unnecessary and in a pocketable / bike light of no use at all)

    Thanks to the wind while biking, no fins are needed



    thats been the pro's; price is the con, imho
    even a full moddoolar host + nailbender + charger + AW cells (2 pc.) is within that "offer"
