Products / Electronic Fluorescent / T5HO


Ultrasave’s line of electronic ballasts for T5HO linear fluorescent lamps is ideal for high bay applications and offer proven performance, reliability, flexibility and energy savings. The ballasts feature programmed start ignition, prolonging lamp life in frequent on-off applications, and multiple input voltage technology enabling operation at any input voltage from 120 to 277 volts or 277 to 347 volts, 50/60 Hz. The ballasts are also designed with multi-lamp capability, operating either 1 and 2 lamps, or 3 and 4 lamps with one ballast, reducing SKU requirements and inventory carrying costs.

A 90°C case temperature rating makes the ballasts ideal for high ambient temperature installations. These ballasts are designed with a lamp end-of-life protection circuit that automatically shuts off power as the lamp approaches its EOL.

The latest addition to Ultrasave’s popular line of electronic ballasts for T5HO applications can operate 1 and 2, or 3 and 4 lamp 54 watt lamp types and has a dedicated input voltage of 480V.
