- An electronic device that can store electrical charge to enable the
start up of a lamp. The capacitor is one of the main components of
an HID Ballast kit.
- In order to start the lamp, an electronic component called an ignitor
must be included in the circuitry of all High Pressure Sodium and some
Metal Halides. This ignitor provides a pulse of at least 2500 volts
peak in order to initiate the lamp arc. When the system is
energized, the ignitor provides the required pulse until the lamp is
lit. It automatically stops the pulse once the lamp has
started. It also furnishes this continuous pulse when the lamp has
failed or the socket is empty.
Starters - Pre-heat operation requires the use of a starter. The
starter causes current to flow through the filaments, heating the
filaments until the starter circuit opens. After the starter contacts
open, the high voltage is applied to the lamps, and the arc is established
in the lamps.
