The Jet Laser is a one channel DMX controllable laser with four individual laser heads. Each laser head emits a 4.95mW red beam so you are getting a combined power of 20mW with all four heads. Its specific design is for those seeking beams and not patterns. Using a DMX controller you can control the On/Off function on each of the four laser heads and create various chase sequences. However, DMX is not required. In fact, the Jet Laser has a total of five operation modes; DMX, Auto, Manual, Sound-active, and Master/Slave. Master/Slave is where you can combine multiple Jet Laser units together and designate one unit as the "master" unit and the "slave" units will do exactly what the master unit does. Our customers often use bounce mirrors to project the beams back and forth across the ceiling creating a vast web of lasers. Truly a brilliant site to see.
