Metal halide lamps combine high luminous output and long lamp life with compact dimensions. Although these lamps have a long starting time, their good colour rendition properties make them a common choice for office lighting systems. The lamps are designed for full-load operation andare not suitable for dimming.


Advantages

  • Good luminous output (62-112 lm/W)
  • Long lamp life (6,000-8,000 h)
  • Good to very good color rendition (Ra > 70)
  • Small size


Disadvantages

  • Long starting and restriking times
  • Not suitable for dimming
