METAL HALIDE LAMP

Application Hints

The optimal focal distance between the lamp and the fibre depends on the diameter of the fibre. A rough calculation of the optimal distance between lamp and fixture can be done by the following formula:

Fd=52mm-D*.077

Fd(mm): Optimal distance between fiber and lamp

D(mm): Diameter of the fiber bundle

UV and IR radiation from the lamp may cause damage to synthetic fibers. Therefore, reflective or absorbing filters are recommended for use with synthetic fibers.

Warning

The lamp emits UV radiation which can cause serious eye and skin damage.  Therefore, the lamp must be used only in closed lamp houses.

Ballast & Ignitor Information

100W lamp-M90; 150W lamp-M81

At the end of their lifetime, metal halide lamps may show rectifier effects causing a rise in current of up to 3 times of the rated value thereby possibly damaging the ballast. Therefore we recommend to use only ballasts with integrated thermoswitch. For line compensation, a capacitor should be used. It is recommended to use ignitors with a timer switch. The use of electronic ballasts is possible if the operating frequency is below 250Hz.
