MHL Metal HalideMedium Pressure Metal Halide Lamps Medium pressure, metal-halide lamps used in a variety of industries including uv curing, printed circuit board and photolithography exposure and industrial graphic arts processing applications. FEATURES & BENEFITS
METAL HALIDE LAMPS USHIO MHL series metal halide lamps contain mercury, scandium and various other metal halogens in an inner bulb that produces a very high light output. As the high temperature of the arc discharge excites the halogenides to evaporate and separate into atoms, the metallic atoms illuminate and release the predetermined target ultraviolet wavelength. The mercury line of 365 nanometers remains present, and although depressed in strength, the combination of these halogenides effect the required ultraviolet wavelengths required for photopolymer, multi-spectrum and diazo processing applications. For the operation of an MHL lamp, bridge-gap ballasts designed specially for metal halide lamps should be used. Bridge-gap ballasts are designed with a higher open circuit secondary and a higher current carrying capacity. A thermal fuse should also be integrated into the ballast. |

SAFETY NOTICES & WARNINGS
|
|
 |
LAMP OPERATION AND SAFETY Metal halogens are extremely active compounds producing high levels of both UV-A and short-wave UV-B and UV-C radiation known to be harmful to the human eye and skin. To avoid danger, the bulb temperature must be maintained within the recommended limits. As the bulb temperature rises, high internal pressure can build to the fracturing point of the quartz; to stay within the safety limits the temperature must not exceed 850ºC. As with mercury vapor lamps, metal halide lamps should be operated and handled only under the direction and supervision of qualified personnel. |
