Basic information: GS = Gap short (shortened electrode gap), DE = Double ended (double-ended lamp), SE = Single ended (single-ended lamp), HMP = HMP lamps can not only be dimmed but also boosted, i.e., operated above their rated wattage, due to their special filling and electrode system. In this case, the photometric characteristics such as color temperature, color rendering index, and luminous efficacy remain virtually constant both when dimming and when boosting.

HMI / MSR / HMP / OMI lamps

• Extremely high luminous efficacy
• Best color rendering
• Three to four times higher luminous efficacy compared to incandescent light
• Light is generated by an arc between two electrodes
• Spectrum similar to daylight (between 4500 and 6500 K)
• Constant color temperature and color rendering behavior over the complete service life
• Metal halide lamps have a spectrum consisting of many lines, unlike temperature lamps such as incandescent halogen lamps.
