Dimming with a phase dimmer

The use of a phase dimmer is only recommended if the dimmer and the LED lamps or luminaires are fully compatible. If they are not then problems can arise during dimming such as flickering and a failure to comply with the electromagnetic compatibility guidelines. In addition LED can become less efficient when dimmed.

Advantages

  • To some extent dimming is possible
    via existing dimmers
  • No additional cabling is required

Disadvantages
  • Dimmed LED can flicker if the dimmer and LED have not been properly matched
  • The lowest limit for dimming is around 10% of maximum brightness
  • Up to 60% less energy efficient when dimmed
  • To some extent fails to meet statutory requirements in terms of electromagnetic compatibility guidelines
