Metal Halide Lamps
- Lamps with UV Control have a quartz material that effectively cuts UVB and UVC radiation. The ConstantColor family of lamps show very little color shift over their life. Generally applies to PRECISE MR-16 and CMH (Ceramic Metal Halide) lamps. PulseArc lamps provide improved lumen maintenance for longer useful life and extended relamp cycles. Operate on ballasts that have igniters to help with lamp starting.
