T5 and T5HO (high-output) fluorescent ballasts power the slim, high-efficacy T5 lamp family used in many commercial lighting applications, including retail display cases, office troffers, high-bay fixtures, and pendant-mounted linear systems. T5 lamps measure 5/8 inch in diameter, significantly smaller than the T8 and T12 lamps they often replace in renovation projects, and their ballasts are sized and wired specifically for T5 and T5HO configurations.

T5 standard lamps (typically 14W, 21W, 28W, and 35W in 2-foot to 4-foot lengths) are suited for moderate-output applications. T5HO lamps (typically 24W, 39W, 49W, and 54W) deliver roughly twice the lumen output of standard T5 in the same physical length, making them common in high-bay fixtures, display lighting, and commercial spaces requiring higher illuminance levels without increasing fixture counts. Electronic ballasts for both types operate at high frequency to eliminate flicker and improve lamp efficiency. Dimming ballasts in the 0-10V range are widely available for spaces where light level control is needed.

RelightDepot carries T5 and T5HO ballasts in standard and dimming configurations from commercial manufacturers. For other fluorescent ballast types, compare with our T8 Ballasts and T12 Ballasts. T5HO replacement lamps are available in the T5HO Lamps section. The full Fluorescent Ballasts parent category covers all tube sizes in one place.
