    3 pcs of high power LED (Philips lumileds type rebel)(output is minimum 230 lumens each)
    1 pcs of current stabilizer (if I can call it that way). I own and run a company which manufacturers LED fixtures so I used a 32V (low voltage) LED drive which gives a stable 700mA current
    And a battery: Lipo 3S (because a voltage drop on one LED is aproxx 3 Volts) so I needed 3 cells for 3 LEDs
    And of course a lenses on LEDs. 2 of them with 60 degrees angle and one is 40 degrees.

    Those are incredibly bright. Some rear LEDs help with your point of reference in the dark as well.
    My son would have those destroyed after one battery though.

    No he won't
    The construction I've made is pretty rigid.
    It allready had suffered like 100 meters of roof slide 3 serious crashes etc.
    About the rear leds.
    I can do that but i need another extra cells of battery in order to feed extra leds

    Aluminium is used because high power leds needs cooling. The cooler they are the longer they last

    Very cool light system, Great work you have here.
    I wanted to do something similar with less power, but never have the time, so I intend just to ziptie my Petzl E99 XP 2 Headlamp on whenever I go camping
