Commercial LED Upgrade

This case contains twenty 48-inch glass T8 LED tubes from GE, each rated at 14 watts and 1750 lumens with a 3500K colour temperature. They are designed as direct-wire replacements for fluorescent lamps in offices, warehouses and retail spaces. The medium bi-pin G13 base fits standard fixtures once the ballast is bypassed.

Facilities Teams Needing Ballast Bypass

Maintenance crews who can rewire fixtures to remove the ballast will benefit from the 50000-hour rated life and damp-location rating. Buyers who need dimmable tubes or a plug-and-play solution that works with an existing ballast should look elsewhere.

Type B Ballast Bypass Required

Each tube operates on line voltage after the fluorescent ballast is removed and the fixture is rewired. This single wiring requirement determines whether the product can be installed in a given project.
