Installation instructions

Helvar ACD-FD wiring

When using ACD-FD, the bulbs used must be dimmable. As a rule of thumb, conventional incandescent and halogen bulbs always dim well. For LED bulbs, check dimmability from the bulb manufacturer’s documentation and our recommendations for the bulb compatibility.


Compact fluorescent (CFL) bulbs cannot be dimmed, they should always be replaced with dimmable LED bulbs.

If a CFL bulb must be used, it should be controlled with a relay.
