With a 1-10V converter, multiple lights can be dimmed in parallel. Work lights without an integrated sensor are equipped with a 1-10V converter as standard. Using 1-10V dimming requires a five-wire wiring system, and manually dimming the lights requires a 1-10V dimmer.
Many Grau Ambiente lights can be equipped with 1-10V converters, but upgrading to the GRAU app control is even more flexible and smarter. You can find more information here.
