Ballast factor is one of the most important choices made by the designer. It impacts light level and energy, and also plays a role in fixture quantity and installation costs.

Use ballast factor to fine tune spacing, light levels, and energy use without affecting lamp life. With ballast life ratings between 60,000 and 90,000 hours, these are one-time adjustments made during project design and last for the life of the project.

Proper use of ballast factor can reduce project costs and simplify lighting controls.
