Does the ALC dim lights without 0-10V dimming? Answer: NO! The ALC needs to be plugged into a 0-10v dimmer for you to be able to adjust high end and low end trim. If it is not, the device is simply a relay that turns the lights on/off. Rana Mohamed July 21, 2020 14:17 Follow Have more questions? Submit a request 0 Comments Please sign in to leave a comment.
