Types of Fluorescent Ballasts

T5 & T5HO Fluorescent Ballast

With our selection of T5 & T5HO Ballasts, you get options that are a specialized type of ballast that expedites the illumination of the T5 lamp-based lighting installation it's fixed to. These reliable lighting solutions are built to last with durable construction from rugged materials. They offer powerful illumination properties and are easy to implement

These high-quality T5 Ballasts have limited coverage and T5HO ballasts are highly useful in high bay fixtures and extensive performance required applications.

These ballasts can be categorized into three variations, as per their level and timing of start-up:

  • Instant Start T5 ballast
  • Rapid Start T5 ballast
  • Programmed Start T5 ballast

T5 ballasts are made of the following components which distinguish them from all other wall lights

  • Watt Capacity
  • Voltage Strength

Thanks to their design, T5HO ballasts have the highest rate of energy efficiency due to the non-heating technique of the electrodes for a startup. Due to their capability of drastically reducing energy usage by around 65 percent, they find many takers in the electronics market.

T8 Fluorescent Ballasts

T8 ballasts come in a multitude of lamping options and also control other types of lamps. We offer a wide selection of brand name T8 fluorescent ballasts such as GE, Phillips, Advance, Espen, and Universal at competitive prices. Our T8 ballasts usually control 1, 2, 3 or 4 T8 lamps of multiple sizes from 1 to 8 feet. A wide range of wattages are controlled as well.

There are really 2 types of T8 ballasts that you may use with different types of tombstones or sockets for your T8 lamps. The first ballast type is instant start with which shunted sockets are used. The second is program start which uses unshunted sockets. The main difference between the instant start ballast and the program start ballast is the ability of the program start ballast to increase the longevity of the lamps in your fixtures using a dusk to dawn, daylight harvesting or motion sensor options.

The program start ballast preheats the lamp cathodes which brings the lamp on more gently than the instant start ballast option. We offer these high-quality T8 fluorescent ballasts in a variety of specifications to find the option that is right for your fixtures. Choose from T8 fluorescent ballasts in various watts, volts, and number of lamps.
