    Voltage range for LED lights

    Sorry to as ask such a simple question for you guys but can I hook up an old LED magic shine light that is powered with 8.4volts (I think) to a 12-14 volt DC system without having any problems? No effects on light lifespan? Like installing on a motorcycle. Thanks,

    You need some additional information on the Magic Shine light. How many LEDs, how are they wired, is there a buck converter ? Most likely you will not be able to jump from the 8.4 volts to 14 volts without frying something.

    Seemed that consensus here was that components on the MS are not rated for 12 volt systems.
    Other issue large voltage/current spikes of cars/motorcycles electrical system.
    Odds are the light would burn up very quickly.
    Doesn't mean you shouldn't try and let us all know for sure.

    If the magic shine uses a contant current driver a resistor could be used to simply drop the voltage a few volts and toss in a capacitor to filter spikes. Since your on motorcycle the power loss in the resistor is of no consequence, i.e. your not battery bound.

    The general Idea was that the MS drivers have some components that are only rated to 10volt.

    Resistor/cap would work, but would burn off a good amount of heat, and wuod be hard to fit in the housing for the light.

    Smile proposal of this connection

    1 pc of LED can accept 3.5V, like the LED type 3528, and 5050 have 3 pcs chips but the chips link in parallel, so the voltage still 3.5v, if you want use 12-14 DC system directly, you need at least 4 pcs LED linked in series connection
