The importance of compatibility with LED lighting and dimmers

Switching to LED lighting will help your home to be more energy efficient and increase the longevity of your lights.

However, the dimming of an LED when using older style dimmers can be difficult as LEDs use very little power, and when these dimmers were designed LED lighting didn’t exist.

If you are updating to LED lighting in your home, it is also recommended to update your dimmers, so that they are compatible and assist with smooth and reliable dimming.

Check for a dimmer that is optimised for LED, how many lights it can control, and that it is designed for New Zealand conditions.

 Issues that can be experienced if LEDs are not compatible with the dimmer

  • Humming sound
  • Lights not dimming at all
  • Lights won’t turn off at low levels of lighting
  • Large jumps in light output when dimming
  • Flickering lights

 Things to consider when updating your home to LEDs

  1. Ensure you select a good quality LED light for your home, and check the dimming capability of the LED with the manufacturer
  2. Update the dimmers to an LED compatible option such as PDL624T or 32LEDM
  3. Talk to your electrician about the areas of your home you wish to be able to dim, so that they can ensure there is sufficient lighting installed appropriate for dimming.

*Wall dimmers are commonly referred to as rotary dimmers, push button dimmers or a rotary dimmer switch.
