Q:
We need to wirelessly control via DMX a 3-piece candelabra which sits on a table on stage. The prop is currently wired for AC bulbs but DC batteries would be used.
A:
At the candelabra, use an RC4Magic DMX4dim. It provides 4 wireless dimmers, each can be assigned to any DMX channel in the universe. Use one channel for each lamp, which gives you the ability to individually control them if need be. And if not, you can either assign all the dimmers to the same DMX channel, or bring them all up and down together in your scenes and cues. The DMX4dim will handle a maximum of 20A shared across the 4 channels, with a voltage range of 5V – 35V. Typically you would use 12V lamps, along with a 12V battery.
The size of the 12V battery depends on the wattage of the lamps you choose, the brightness you will run them at, and the total running time between charges.
(we do not supply them directly)
