Osram 400 W Linear Metal Halide Lamp, Fc2, 38000 lm

Double ended clear white light output
Ideal for display/floodlighting
Designed for use with ignitor/starter circuits

These lamps require 2 to 10 minutes to cool before re-striking, but shorter times are possible if installed in fittings with high voltage ignitor circuits.
Care must be taken NOT to touch the glass surface of the lamp during installation.

Metal Halide

These lamps produce a clear white light and are suitable for display or floodlighting, where the heat output from tungsten halogen lamps would create a problem. Metal Halide Lamps have an efficiency approx. 4 times higher than halogen lamps and xenon lamps. In addition, the short-arc type is similar to a point light source, making optical design easy. As their colour temperature characteristics are similar to daylight colour, exact colours (RGB) can be reproduced. They can also be used for both high bay and low bay applications.,Compared to High Pressure Mercury lamps, Metal Halide lamps offer greater efficiencies and, compared to high pressure sodium (SON) lamps, they have similar advantages, but have different output characteristics. A disadvantage of metal halide lamps, when compared to SON lamps, is that they have a shorter service life.
