A low wattage metal halide discharge lamp includes an evacuated envelope wherein is disposed a heat reducing member having an arc tube therein. The heat reducing member and the arc tube have a metal band an outer strap member adjacent one another and adjacent an electrode with the metal band,...
It has been shown that with a ceramic envelope it is possible to realize metal halide automotive headlamps, which can be applied in reflectors without any shielding. In comparison with quartz lamps the lamp power is considerably lower. This not only results in energy saving but also in less ...
Even if you are using a brand new 1000-watt metal halide bulb, there is a second factor that contributes to lumen loss and that isthe need to use a reflector to focus light. When light is created by an omnidirectional bulb, like a metal halide, it needs reflectors to gather, collect,...
A family of medium wattage ceramic discharge metal halide (CDM) lamps operating on magnetic ballasts was introduced several years ago to the North American market. These medium wattage (MW) lamps (175W - 400W) provide excellent color consistency, high color rendering properties, and long life. ...

The fill includes a buffer gas, optionally mercury, and a halide component comprising a sodium halide, a lanthanum halide, a thallium halide, and a calcium halide. The lanthanum halide is present in the halide component at a mol fraction of at least 0.03.Ramaiah, Raghu...
A new approach to design of low wattage metal halide lamps has been used in order to minimize the end losses and to make the wall temperature more uniform. Using the method suggested by Elenbaas, the lamp's absolute total radiation was measured as a function of input power for discharge ...
A low wattage single-ended metal halide arc discharge lamp has an isothermal arc chamber with an outer diameter (t) substantially equal to the product of a first constant and the lamp wattage plus a second constant; a fill gas and a pair of electrical conductors sealed into and passing ...
