Generally, metal hallide lamps fare quite poorly in terms of reliability but some lamps have an outright poor performance. The aggressiveness of metal hallides and their reliance on a specific pressure and temperature requirement for vaporization and light output with a specific output, means that lamp to lamp colour shifts are quite noticeable. Aging amplifies the colour drift and light output differences. As the lamp is very compact and has high temperature hot-spots means that fixtures are noticeably degraded and especially affects gaskets and the front frame of the reflector housing. This means that waterproofing is frequently degraded and lamps are rarely suited to operate outdoors unless old fixtures are carefully maintained. | Generally, metal hallide lamps fare quite poorly in terms of reliability but some lamps have an outright poor performance.
