This is the Rako RMT500, a compact 500W RF dimmer designed to fit through a standard down-light cut-out and working with dimmable GU10 LED lamps, tungsten, and low voltage halogen lamps. It uses trailing edge dimming technology, which gives it smooth quiet dimming of electronic transformer fed loads and it maximises dimming performance of most GU10 LED downlights.

This wireless dimmer is connected in-line before the first light fitting in order to enable dimming of up to 500W of trailing edge dimmable loads, and it can be controlled from any Rako Rakom RF device, for example the Rako RCP/RCM push button RF wall-plates.
