Economy D2S HID Bulb

D2S is short for "discharge second generation shielded". These are found in vehicles that have projector headlamps with a light shield. You can spot a D2S capsule by looking at the glass - if there is no metal shielding around the glass, you have a D2S. Provides about 10% more light than the identical D2R bulb. Unlike halogen incandescent lamps, the economy D2S bulb does not have a filament. Instead, it creates light from an electrical discharge between two electrodes in a micro-environment of xenon gas, mercury, and metal halide salts that are hermetically sealed in a tiny quartz capsule. The arc tube is encased in a glass jacket to filter ultraviolet rays. The light is emitted by an electrically energized gas -- a plasma discharge -- formed and sustained between two electrodes. The Luminarc system includes an electronic ballast that controls the arc ignition process and sustains the arc in normal operation.
