    I wanna use LED light Mr16s connect to 24V pv panel.
    the input voltage of Mr 16s is 12V.
    but somebody tell me that i can use it in 24V system.
    can the led light survive under this voltage?

    or is there a 24V version LED Mr16s available in the market?

    and i wanna control the dimmerable LED automatically by using PWM,
    could you tell me which on LED driver or controller is best for Mr16s?

    Thanks very much

    MR16s were originally Multifaceted Reflector lamps used in accent lighting etc. LED versions are now made in similar sizes, although the reflector may be redundant.

    I would be surprised if you could run a resistor-ballasted LED lamp off double the design voltage, even with a narrow PWM. The extra dissipation in the resistors would be very large. Perhaps two lamps in series would be OK.

    Not sure, but it looks promising. Where are you thinking of buying one?
