Dimming Electronic Ballast For One F28T5 Fluorescent Lamps.
Brand | Universal Douglas |
Input Volts | 120/277 |
Number of Lamps | 1 |
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 Lamp Type
The type of bulb the ballast can fire.
| T5 |
Start Type
For Ballasts, indicates the method the ballast uses to start its bulbs. HID ballasts can be Probe or Pulse start. Fluorescent ballasts can be Rapid, Instant or Programmed start. For HID and Fluorescent bulbs, indicates the start-type of ballast that the bulb will work with.
