Description
Replacement 4 x F54T5HO T5 Light Ballast | 120-277V | High Power Factor | Program Start
The Keystone KTEB-454HO-UV-PS is a T5HO electronic program start ballast engineered for commercial and industrial fluorescent lighting installations. It accepts 120V to 277V input without manual switching, making it a practical choice for facilities with mixed or unknown voltage supply. The program start ignition method extends lamp life by eliminating cathode stress during each startup cycle, which reduces maintenance frequency in applications where lamps cycle on and off regularly.

Frequently Asked Questions
What lamps does the KTEB-454HO-UV-PS work with?
This ballast is compatible with F54T5HO, F54T5HO/ES (49W), FT55W/2G11, FT50W/2G11, FT36W/2G11, and F58T8 lamps in 1, 2, 3, or 4 lamp configurations. Refer to the wiring diagrams for each configuration.
What voltages does this ballast accept?
The KTEB-454HO-UV-PS accepts 120V to 277Vac input at plus or minus 10% without any manual voltage selection required.
Can this ballast be used in outdoor fixtures?
Yes. It is UL and cUL Listed Type 1 Outdoor and rated to start in temperatures as low as -20 degrees F.
What is the warranty on this ballast?
Keystone provides a 5-year warranty on the KTEB-454HO-UV-PS.
What is program start and why does it matter?
Program start preheats lamp cathodes before striking an arc. This reduces stress on the lamp during each ignition cycle and extends lamp life, particularly in switching applications.
Are prior versions of this ballast available?
The current version is D3. Prior versions exist. Contact Keystone Technologies directly for spec sheets on earlier versions.
