The newest generation of the H17 is smaller and lighter than its already-compact original. The smallest body is less than a foot in diameter, and the entire family delivers incredibly high output, replacing up to 1000W MH while boasting even higher efficacy than before…all at a rock-bottom price. The H17 includes an expansion port that makes it easy to screw on standard or Lightcloud Blue-enabled passive infrared (PIR) and microwave (MVS) sensors, which can be configured to adjust brightness and hold time, saving additional energy and costs. A remote is also available for an additional level of control. H17B – RAB Lighting  Spec sheet: H17B
