    Hi All,

    I am planning to build a light with 10 Watt LEDs. These LEDs work on 32 V.

    What do you think of connecting 6 or 7 of them in series and power it with 220 V Ac?
    :confused::confused::confused::confused:

    Regards,
    Devil

    Hello,

    When you want to power them directly from the mains, you will be violating the ToS.
    We do not allow any direct mains powerd devices.

    Its a BAD idea for a number of reasons..

    with high vf LEDs like 32VDC you really only want to run each on its own string to keep working voltages in safe DC levels under 60V.
    I would use a 48VDC power supply with 6 constant current drivers (like meanwell LDD drivers) feeding each LED.
    or dedicated AC/DC constant current drivers (like meanwell LPF) for each LED.

    There are higher voltage DC output drivers BUT they are meant for trained users who are aware of the dangers with higher voltage DC. (greater than 60V)
