Dimmers & Switches

Dimmers & Switches. Dimming controllers for retrofitting smart brightness control onto existing lighting circuits, including trailing-edge (standard domestic dimmer-compatible) and 0/1-10V units for driving LED drivers and DALI-compatible fittings directly. Check your existing bulbs and drivers are dimmable before buying — LED dimming compatibility varies by bulb, and 0-10V/DALI units need a compatible driver on the load side, not a standard bulb. The Bypass accessory is a fix for flicker on low-wattage LED loads, not a standalone product.
