The fastest upgrade to existing fluorescent tube fixtures to energy efficient LED lighting. These lamps are ideal for fixtures using double ended lamps, a lamp that have line and neutral pins on the opposite side of each lamp, most common with fluorescent linear lamp fixtures.
By using a ballast bypass design, there’s one less possible point of failure, making the fixture more reliable. Ballast bypass LED tubes will also save time finding a compatible ballast.
Product Features
- Replacement for conventional fluorescent lamp
- 50,000+ hour lifetime
- Approximately 40% more energy efficient than standard F32T8 lamps
- Environmentally friendly: No mercury used
- Instant startup
- Frosted lens eliminates pixelation
- Integral driver (isolated) eliminates need for external driver or ballast
- UL classified
Wiring Diagrams
1. Cut all existing connections to ballast as shown below and remove ballast. See Figure A for typical ballast configurations.
2. Re-wire fixture as shown below. For double-wiring, use either shunted or non-shunted lampholders. (Note: There should not be any exposed wires at the end of installation.)
