Rated at 250, 400, 1000 and 1500 watts, the high intensity discharge lamp, parabola-shaped reflector and light ballast are each sold separately.

A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps sodium-vapor lamps and neon lights.
33.
Geissler invented the first gas-discharge lamp, the Geissler tube, consisting of a partially evacuated glass tube with a metal electrode at either end.
34.
Although discharge lamps based on low-pressure mixtures of xenon and a chlorine donor emit incoherent light, they are reliable and easy to operate.
35.
Z1 designer Harm Lagaay mentioned that Z1 production helped generate patents for BMW's high-intensity discharge lamp, integrated roll-bar, door mechanism, and underbody tray.
36.
Brand new high-intensity discharge lamps make more incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared.
37.
In gas discharge lamps, such as flashlamps, current density plays an important role in the output emission and tend to favour longer wavelengths.
38.
Perhaps his best recognized effort was the book, coauthored with W . E . Forsythe, titled " Fluorescent and Other Gaseous Discharge Lamps ".
39.
However, they are ineffective with sources such as fluorescent or discharge lamps, whose light varies in color and may be harder to correct for.
40.
Light-emitting diode ( LED ) lamps have replaced high-intensity discharge lamps ( HID ) as the most power input, but are not yet as widely used.
