Product Line


Input Volts

Output Voltage
A measure of electrical potential, expressed in volts. Voltage "force" is the measurement of pressure that pushes electrical current through a conductor.
Output Watts
The transformed power output from a transformer.
Operating Temperature (°F)
The ambient temperature in which the product can safely operate.
-4 to 194
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.
Width (in)
For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
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.
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.

Maximum Current (Amps)
The maximum amount of Amps that a ballast can hold.
Maximum Load (Watts)
The maximum power that a product can handle.
Damp Location
Suitable for an exterior or interior location that is subject to condensation of moisture in, on or adjacent to electrical equipment
Indicates whether a product can be dimmed in conjunction with a suitable dimmer control.
