Philips Lighting 150 W Tubular Metal Halide Lamp, RX7s, 13250 lm

These lamps are fully compatible with the traditional metal halide type, with the same physical dimensions, also using use the same control gear
The clear outer Quartz envelope is UV- block
Constant colour temperature maintained without the colour drift experienced by the traditional type
Improved colour rendering and light (lumen) output

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.
