    All those pics, but no beam shots?

    That's the most important aspect of a light.

    Got 2 for you.
    1. What input voltage is required?
    2. Explain the 4 options in the ordering process.
    cutter k-light

    Tell me what you would recommend for a 45 minute commute in the dark (all road).

    Man, that looks awesome! Can't wait till I have some disposable cash to buy that!

    My only question/want is for a recommendation for different types of battery setups to power that. With differing optimizationsn or something basic at least. One of those so I got the light engine, now what type questions.

    Hey,
    1. it fits the Bflex best, so 14.4v is ideal, lipo or liion is good, I also have 18650 cells battery holders in stock (ktronik, not cutter) that could be used as well...you can buy cheap 18650 cells through DX ect...

    2. first box: optics, go narrow for road, 10507
    second box: tint & flux of LED, go for R2x3 WG cool for road, Q2 or Mixed for off-road
    third box: cutter will solder up the driver if you are lazy
    forth box: you have to buy the bflex, I guess it for if you already have one...


    So for your 45min ride (road) narrow lens, R2 LED (630lm) & 2200mAhr / 14.4v batt + good charger or cheap charger off DX...

    hope that helps

    14.4v lipo / liion or dynamo driven (with bflex stepdown driver)

    Pretend I know nothing about batteries or battery systems. I just want the light to work - could you recommend anything specific?

    4x 18650 li-ion cell, wired in series. In a 18650 battery holder... maybe in a waterbottle or something...cheap & cheerfull
