Key Differences
A ballast is a device used to limit the amount of current in an electrical circuit, primarily in lighting applications. It helps to start and then stabilize the current that drives fluorescent and HID lamps. On the other hand, an ignitor is specifically designed to initiate the arc in discharge lamps such as metal halide and high-pressure sodium lamps. It generates a high voltage pulse to light the lamp.
Ballasts are crucial for controlling the operating current and providing the appropriate voltage to start lamps. They ensure that the lamps do not draw more current than they are designed for, which can increase lamp life and efficiency. Whereas ignitors are used only at the startup phase and do not regulate current during normal operation.
The operation of a ballast can be either electromagnetic, which is older technology, or electronic, which offers more efficiency and better control of the light output. Ignitors, however, do not vary much in technology and primarily focus on providing the necessary voltage spike to initiate the lighting process.
In the context of maintenance and replacement, ballasts are generally more durable but can be more complex to replace due to their integration into lighting systems. Ignitors, while typically simpler and smaller components, might need more frequent replacement depending on the usage cycle of the lamps.
Ballasts contribute to the overall energy efficiency of lighting systems by regulating electrical flow and reducing wastage. Ignitors, while essential for starting the lamps, do not directly influence energy efficiency during the lamp's operational phase.

Common Curiosities
What does an ignitor do?
An ignitor provides the necessary initial spark to start discharge lamps like metal halides.
Can a lighting system work without a ballast?
No, fluorescent and HID lamps require a ballast to control and stabilize the electrical current.
Are electronic ballasts better than electromagnetic ones?
Yes, electronic ballasts are more energy-efficient, provide better control, and are less noisy than electromagnetic ballasts.
What is the main difference between a ballast and an ignitor?
A ballast regulates and stabilizes current throughout the operation of the lamp, while an ignitor is only used to start the lamp.
Is it easy to replace an ignitor?
Replacing an ignitor is generally straightforward and can be done as part of regular maintenance.
How often should ignitors be replaced?
Ignitors should be checked and potentially replaced during routine maintenance, depending on usage.
What happens if a ballast fails?
If a ballast fails, the lamp may not start, may flicker, or can overdraw current, potentially leading to failure.
Do ballasts affect the color of light produced by a lamp?
Ballasts do not typically affect the color of light but can influence the intensity and stability of the output.
What is a ballast and why is it important?
A ballast regulates current to prevent excessive energy flow and stabilize light output in electrical lamps.
How does an ignitor impact the efficiency of a lamp?
