25 Pack - 4 Foot - 14 WATT - 3500 Kelvin - LED T8 Lamp Replacement - Dual-Ended Bypasses Existing Fluorescent Ballast - Eliminate The Need to Replace tombstones'

The DEBP (dual-ended bypass, which is hot on both ends) Series of LED T8 lamps replace conventional fluorescent lamps in existing luminaires. Offering significant energy-efficiency and lifetime improvements over fluorescent lamps, DEBP Series lamps are installed by bypassing existing fluorescent ballasts, and hard-wiring tombstone lamp-holders directly to incoming AC power leads. Dual-ended bypass lamps eliminate the need to replace shunted tombstone lamp-holders in existing fluorescent luminaires with instant-start ballasts. Available in 3500k (warm/neutral white), Long-life LEDs provide up to 90,000 hours of operation with at least 70% of initial lumens output (L70).** Models provide 1,100 to 5,500 lumens per lamp, and 121 to 129 lumens per watt (LPW).* Uniform illumination with no visible LED pixilation Universal 120-277 AC voltage (50-60Hz) is standard Power factor > 0.90. Total harmonic distortion < 20% Color rendering index ? 80. Full glass housing inhibits yellowing and distortion Easy installation in existing fluorescent luminaires. Bypass models connect directly to incoming AC power leads. * contact factory for other color temperatures and lumen packages. **L70 hours are IES TM-21-11 calculated hours.
