WOW is right! 168 ultra-bright LEDs (68 red, 46 green, 44 blue) arranged in circular patterns chase and flash in dozens of preset patterns. Sometimes it’s “blossoming”, sometimes shrinking, sometimes a full-on strobe light. Rear controls include a rotary flash speed control knob. A pushbutton selector switch puts it into sound-active mode: use the rotary audio sensitivity knob to make it flash to the beat of music! A club, DJ or band can install several of these and they’ve got a bright, flashy sound-active light show! Only 15 watts. 8” x 6” x 8”. 3 lbs.
