4-Lamp LED Driver for T8 Tubes

The GE 88139 is a constant-current driver built to run four T8 LED tubes in commercial and institutional fixtures. It accepts 120-277 volt input and delivers 72 watt total output, making it suitable for office, retail and warehouse relamping projects. Supplied as a case of 10 units for multi-site or volume installations.

Compact metal case with 0-10V control

Measuring 9.5 x 1.3 x 1 inches, the enclosure fits standard ballast compartments and surface-mount channels without modification. The 0-10V dimming interface works with common wall-box dimmers and building-automation systems for smooth, flicker-free light-level adjustment. Class 2 rating simplifies wiring and inspection requirements.

Replaces magnetic ballasts in 4-lamp fixtures

This driver upgrades older fluorescent ballasts in four-lamp T8 troffers, strips and high-bays where 0-10V dimming is desired. The jump is worth it when the existing ballast has failed, when energy codes require dimming, or when a maintenance team wants a single driver SKU for multiple voltage supplies. Not suited for two-lamp or single-lamp configurations.

Questions about this item

What voltage range does the 88139 driver accept and what does 0-10V dimming control?

The 88139 driver operates on 120-277V input and the 0-10V interface dims the connected T8 LED tubes down to low light levels.

What are the exact dimensions of each driver so I can check ballast compartment fit?

Each driver measures 9.5 inches long, 1.3 inches wide and 1 inch high, so verify your fixture cavity against those figures.

How is the driver wired for a four-lamp retrofit and which step is often missed?

Connect the 120-277V supply to the input leads, wire each of the four lamp sockets to the output leads, and run the violet and grey 0-10V wires to the dimmer — the step often missed is capping the unused dimming leads when no dimmer is installed.
