Just curious why ETC hasn't introduced a Quad - 10A module for their Sensor racks similar to Strand and Leviton? I realize there is a dual 10A "low wattage" module; but at the same price as the D15 or D20, its not worth it + my understanding is that this is intended for LED and other types of loads. In my opinion a 15 amp module is overkill for our plans - to have a single dimmer for each circuit; and only a single fixture per circuit. Realistically a standard Source Four will have a 575 or 750 watt bulb; at 120 volts, that's 5 to 7 or so amps (when on full power). I know the SmartPack come in 12x 10amp capacities, but we are looking for 80+ channels; and I don't for-see installing 6 or 7 wall packs. When reviewing list pricing on the SmartPack system, you've managed to offer a 10amp dimming channel very close to half the price of a 20amp dimming channel. (or a 10am at close to the same price as 2x 10 amp channels). Conventional wisdom would indicate that the same philosophy could be applied to the Sensor modules.
