Hi All

I have been investigating Metal Halide Lamps and unlike LPS, HPS and Mercury
Lamps they seem to be different

Som Lamp Manufacturers mak them for use on a standard Mercury ballast in
conjunction witha 750 volt ignitor also there are lamps which uses a Mercury
ballast in conjunction witha 5000 volt ignitor ther ore some which operate
on HPS ballasts and 5000v ignitors or Metal Halide ballasts and 5000v
ignitors and ther a CWA Constant Wattage Autoleak Ballasts with NO ignitors

So confusing what wold happen if say accidently use a Mercury type Metal
Halide on HPS Gear or a CWA lamp on Mercury or HPS gear, I have heard that
these lamps can Explode if missused.

So far I have a Venture Parmar Catalogue and there are say for a 250w MH
lamp about 10 different designs

So Confusing

Yes, there are a lot of different lamp types, but choosing a ballast
is not that confusing. The lamp box or the catalog has a ANSI ballast
designator. Use the lamp ONLY on the recommended ballast type. Metal
Halide lamps can and do explode, and will likely explode if used on a
ballast that provides substantially more current than the lamp is
rated for.

Also, unless the lamp is rated for use in open fixtures, make sure the
lamp is used in a fixture that can contain hot flying glass and quartz
particles. And, many metal halide lamps are designed (and designated)
for base-up, or base-down, or either base-up or base down. Do NOT
operate these lamps in orientations other than the recommended
orientation, as that will increase the possibility that the arc tube
will explode.
