A clear 48 inch T8 LED tube with white finish

GE

GE 31919 LED Tube Light Bulb 48 inch T8 15-Watt 3500K 2050 lumens Ballast Bypass Type B

SKU CH-JKQ8-WK6W7

A case of 20 four-foot T8 LED tubes delivers 2,050 lumens each at 3,500 K while drawing only 15 watts and bypassing the ballast

  • Ballast bypass simplifies LED conversion without full fixture reinstall
  • 15-watt consumption delivers 2050 lumens for efficient operation
  • 3500K warm white creates comfortable neutral lighting
  • 48-inch T8 form factor fits standard linear fluorescent fixtures
  • Case of 20 tubes supports large-scale lighting projects

Product identity

This case contains twenty GE LED tube lights, each a 48-inch T8 replacement rated at 15 watts and 3500K colour temperature. They deliver 2050 lumens per tube and are designed for ballast-bypass Type B installation in existing linear fluorescent fixtures.

Sustained operation

The tubes run at a steady 15-watt draw with no ballast in the circuit, so heat output remains constant during continuous use. Non-dimmable operation means light output does not vary, making them suitable for areas where lighting stays on for long periods.

Installation limits

Type B wiring requires the installer to bypass or remove the existing ballast and connect line voltage directly to the sockets. This approach eliminates ballast compatibility issues but does require electrical work that a standard fluorescent tube swap does not.

Questions about this item

How much heat does a 15-Watt tube produce when running continuously?

Each tube draws 15 watts, so nearly all of that power becomes heat rather than light, making it noticeably cooler than the fluorescent tubes it replaces.

Does the ballast-bypass design require rewiring the existing fixture?

Yes, the Type B design means the internal ballast must be removed or bypassed and the tube wired directly to mains voltage.

Can these 3500 K tubes operate in the same fixture as older fluorescent tubes?

No, the ballast must be bypassed for the LED tubes, so any remaining fluorescent tubes on the same ballast will not work.
