    This is my homemade light.
    It has 4 cree XR-E leds. You can move independent each led. I use BFLEX board and 18V battery.

    Nice work, thank you for sharing!

    Do you have any more details of you lights construction, like what reflectors or optics have you used? I like your mounting system with independent light heads.

    Hi!
    The reflectors are Cree Secondary optics "very narrow beam" and battery is 18V but I have tested it with multimeter and it mark 20V.

    Most cells chemistries will read a little higher voltage then their rating when freshly charged with no load.

    Happy trails!
