Josh Ferris from Praise Church in Beaumont, TX brings us these small towers of blinder lamps.
They wanted the feel of incandescent without the cost associated with commercially available products. The most complex issue was designing a system that would allow a certain degree of mapping without requiring a ridiculous amount of dimming. Due to cost, conventional rack dimmers were ruled out fairly quickly. So they started researching low amperage products leading them to the Doug Fleenor DMX24DIM.
Further calculations indicated that by using 45w lamps, they could stack (2) lamps on each dimmer circuit, although barely. Assuming a purchase of (2) DMX24DIM units, they landed on a final count of (48) dimmer channels with (2) lamps per dimmer circuit distributed across (16) vertical towers.
Having seen a few other churches successfully use clamp lights for this type of application, they knew that was the direction to go. However, having overbuilt their fair share of stage props, they were dedicated to engineering a lightweight and sturdy framework. The idea of using 1/2″ EMT (conduit) came quickly, but building an appropriate base took some trial and error. In the end, the towers were very lightweight, quite stable, and sturdy enough to handle an occasional collision from band members.
