Light Ballast, HID Ballasts, Electronic Ballast and Lighting Ballast Capacitor Types

For more information about Ballasts check out our blog post entitled "What is a Ballast?"
A transformer is a device that is designed to control the amount of current in an electrical circuit. One of the most common examples of a modern inductive transformer is one used in a Fluorescent Lamp. The transformer limits the current throughout the tube which could possibly otherwise reach destructive levels because of the tubes negative resistance characteristics.

There are various transformers that differ in usage and complexity. Fluorescent Ballasts are one of the most common forms used today. The Fluorescent type is used on many common different fluorescent tube types like: T12, T9, T8, and T5. HID or High Intensity Discharge Ballasts are used to limit the current for Ballasts that run Lamp types like Metal Halide, High Pressure Sodium, Low Pressure Sodium and more.
Emergency Ballasts are designed to power Emergency Fixtures during a power out. An Emergency type is meant to power the fixture or fixtures for 90 minutes or more during an emergency situation.

Starters and Capacitors are used with HID Ballasts. Starters, also known as ignitors or igniters, are used to start or "ignite" the lamp. Capacitors aka Condensers are designed to store electrostatic energy. The Capacitor contains at least two electrical conductors separated by an insulator.
