    Default I do not know what is the best driver for two types of LEDs

    Hello, I wanted your help, I have a battery pack from 11,1volt, and I have to feed these LEDs:

    first led - https://www.led-tech.de/en/High-Powe...4_120_212.html

    second led - https://www.led-tech.de/en/High-Powe...8_120_170.html

    you tell me, please, with which drivers can feed them, without burning the LEDs, please for a LED driver, can you help me
    Thank you

    Hello,

    With your 11,1v battery, you need a linear driver for the first led (eg. battery voltage is more or less led voltage) and for the second led, you need a buck driver (led voltage is smaller than battery voltage).

    There are good led drivers at taskled. There are several drivers available, maybe someone can help you to choose the best for your case.

    Uh, no. That would be a buck-boost, or sepic driver. Linear drivers require the battery voltage be higher than the LED voltage, just like buck drivers.

    Taskled's b3flex would work well on the XML2, but he does not make buck-boost drivers.
