Did you [john.golden] accidentally get the coil voltage and contact
voltages reversed, or are you indeed using a 120V control voltage and a
12V DC lighting circuit? As I recall, most of the SmartHome equipment
assumes that the lights will be at full line voltage, although they may
have some low-voltage equipment for outdoor use. I would have assumed
that an industrial lighting circuit would be powered by line voltage.
Also, since you said you wanted to dim the lamps, you will need a dimmer-
based (TRIAC-based) device, rather than a simple relay, which would only
give you on/off control, not dimming.
