Description

The Ushio MHL-70 is a 70 watt HID UV Metal Halide bulb with Single Ended G12 base.
The MHL-70 metal halide lamp has a Average Rated Life of 500 HrsUSHIO 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.

Warning: Only Use in UV Protective Housing!
