  • Bright light cheap bulb with controller and optics

    posted by GammaButa on 01/17/2013

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month


    - very bright light

    - can work from 12V adapter, car battery, other battery packs near 12Volts

    - tested and worked fine from solar solar panel with 18Volt starting voltage

    - only need 300-320mA of input current, leds are connected serially

    - for DIY porjects all the components can be also usefull (driver circuit, LEDs, metal heatsink housing, plastic optics)

    - easy to modify, to further improve efficiency


    No reals cons at all, a little warm while working, the first one I received did not have thermal grease inside under the LED panel, but the second I've got had.
    Non of them had problems yet.


    I disassembled it and also measured voltage/current plus how to improve efficiency, pictures will be attached about internals and how to mod.


    It is one of the best 12Volt bulbs here if not the best.
