Thus, some ballasts have a separate circuit that provides a low voltage to heat the lamp electrodes during lamp starting and typically during lamp operation Hammer, Traditionally, ballasts are designed to operate a specific number usually one to four and type of lamp such as a four-foot T8 lamp at a specific voltage in North America either , , or volts.
Thus, to find a ballast compatible with a particular luminaire light fixture , lamp type, lamp quantity, and line voltage must all be known.
Fluorescent Ballasts. Ballast Wiring Diagram. Lamp Compatibility Table. There are four basic types of fluorescent ballasts: Instant start electronic ballasts use a high starting voltage about volts to start very quickly less than 0. Up to 4 lamps. Fluorescent 32 watts. T8 lamp.
Fluorescent Ballast Labels The label on the ballast shows two important labels. Lamp compatibility table type of lamps that can be used with this ballast Ballast wiring diagram shows how the ballast is wired to the lamps Fluorescent Tube Diameters Fluorescent tubes have two common shapes, straight and u- shaped.
Matching a Ballast with a Lamp There are three requirements when matching a ballast to a lamp. In the example above, lamp type F32T8 has the following three requirements: 1. Fluorescent lamp 2.

Electronic ballasts can put out multiple frequencies of electricity without altering the input voltage. This eliminates any flickering and buzzing. The process for swapping out magnetic ballasts for electronic ballasts is pretty simple and straightforward.
This is the direction the lighting industry is headed in, so why not swap them sooner rather than later to optimize your space with better, quieter lighting? Fluorescent ballasts use three different types of starting technologies: rapid, instant, and programmed.
Rapid start ballasts work kind of like preheating an oven. Imagine if an oven was preheated all the time so you could bake cookies at any given moment. Rapid start ballasts rely on this preheating method so when the light switch is turned on, the lamp turns on right away. Have you ever hit a light switch and received a strobe light effect? Instead, they send a high amount of voltage across the lamp upon the strike. Typically, instant start ballasts use 1.
Instant start lamps also start reliably at temperatures as low as zero degrees. Programmed start ballasts are typically paired with occupancy or motion sensors. Another perk of a programmed start ballast: it maximizes the number of lamp starting cycles while maintaining energy efficiency.
Programmed start ballasts are also reliable at low temperatures. Probe start ballasts are the older type and not very easy on the HID lamp. Electrons jump across the arc tube between two operating electrodes.
