Rotary dimming, made for ARIA.
Dim the light. Lift the finish.
ADM250X
250W Externally Switched Rotary Dimmer
ARIA’s Externally Switched Rotary Dimmer keeps familiar rotary control inside the ARIA fit-off, with on/off handled by a separate switch. A smooth turn delivers trailing-edge dimming from 2W to 250W, with mechanical minimum-brightness adjustment to tune the low end to the load. Inside the pack, Matte White, Matte Black and Dark Grey dials suit any ARIA switch plate. Two-wire connection means no neutral is required at the dimmer. Compatible with dimmable LED, incandescent and halogen loads, it’s a good choice for jobs that need broader load compatibility and separate switching without breaking the ARIA finish. Backed by a seven-year parts-and-labour warranty.
