CT4 BEAM uses a customized long-life 400W lamp from Ushio, saving more cost compared to lighting using traditional lamps. The beam angle is only 1.6 degrees. CT4 BEAM can create a sharp and powerful mid-air effect. Two independently controlled and overlapping prisms further enhanced the mid-air effect. A frost system helps to soften the beam effect gives more possibility to the users. CT4 BEAM is a good choice for concerts, bars, live shows, etc.
