Downlight with glass diffuser - 2 finishes

Standard dimmers are recommended for mains voltage lighting only.

Leading edge phase cut dimmer

Good quality leading edge dimmers can be used on wire-wound transformers and compatible electronic transformers. If audible noise is produced we suggest you change to good quality dimmer from Richmond Lighting.

When selecting a dimmer add up the wattages of the bulbs (or transformers) you wish to dim and choose a dimmer with a suitable maximum load rating.

Trailing edge transistor dimmer

For use with dimmable electronic transformers (that are compatible with trailing edge technology).
These dimmers are not suitable for wire-wound transformers.

When selecting a dimmer add up the wattages of the bulbs (or transformers) you wish to dim and choose a dimmer with a suitable maximum load rating.
