Dimming high voltage LED

  • I'd like to dim an aquarium LED light. Checked that DC going into LED bar is approx 134V and 37W. AC component is less than 2 voltage. Only one channel. Didn't see any electronics on LED bar, just LED elements glued to aluminium bar.

    As Dimmer 2 specs says " Dimmable LED: 50-200VA / 10W – 200W" - would it be able to handle this?

    Actually I have two identical LED lights. Assuming I would find power source powerful enough for two can I control two LEDs with single dimmer?

    Can it use DC for powering itself?

  • Dimming an LED light is as easy as adding resistors to the connection or even several resistors, to ensure you get the right brightness – this is called analog dimming. ...

You might not have as much control over the brightness as you would using pulse-width modulation (PWM).
