Ballast Factor

The percentage of a lamp's rated lumen output that can be expected when operated on a specific commercially available ballast. For example, a ballast with a ballast factor of 0.93 will result in the lamps emitting 93% of their rated lumen output. A ballast with a lower ballast factor results in less light output and also generally consumes less power.

Ballast Type

Magnetic ballasts are a legacy technology and use inductance to transform the line voltage to the voltage required to "fire" or excite the gasses in a lamp. Electronic ballasts use a variety of starting methods, and are more efficient than magnetic ballasts in converting input power to the proper lamp power and operate fluorescent lamps at higher frequencies, resulting in an overall lamp-ballast system – increasing efficacy 15% to 20% over a magnetic equivalent.
Ballast Type

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Length (in)

Width (in)

For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
Width (in)

Height (in)

For ballasts and fixtures, height is the measurement of total vertical distance from the top of the product to the bottom expressed in inches.

Power Factor


Total Harmonic Distortion (THD)

Total harmonic distortion, or THD, is the measure of how much a ballast can distort the waveform of that building’s power supply and interfere with other equipment. Electronic ballasts today are rated at less than 20 percent, 15 percent, or less than 10 percent THD. The magnetic ballast is rated in the 20 to 28 percent range. The lower the THD the better and more efficient the ballast, and the less likely it is to interfere with other electronic equipment.

Product Notes: Dedicated voltage models used most often in pre-existing fixtures. Using Reduced Harmonics (.88 Ballast Factor) Standard Ballast Factor ballasts will provide consistent, efficient light. Typical Application: Industrial factory and warehouse space with basic, no-frills overhead lighting.

How many watts of electric does this ballast use


This ballast can be used with a number of lamp configurations. The lowest system watts is 63 (4 - F17T8's) and the highest system watts is 112 (4 - F32T8's). The number of system watts would be dependent on the quantity and type of bulbs used with the ballast.
