The DM (dual mode) Series of LED T8 lamps replace conventional fluorescent lamps in existing luminaires. Offering significant improvements over fluorescent lamps in both energy-efficiency and lifetime, DM Series lamps offer the flexibility of both bypass and direct replacement, plug-and-play lamp replacements. With DM Series lamp replacements, existing ballasts can initially be used in the plug-and-play mode. When existing ballasts reach the end of their useful lives, DM Series lamps can then be hard-wired to incoming AC power leads.
Available in 4000k (neutral white) and 5000k (cool white) color temperatures.
Long-life LEDs provide 56,000 hours of operation with at least 70% of initial lumen output (L70).
Provides 2,200 lumens per lamp, and 107 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. Dual mode models can function as either (1) bypass models, which connect directly to incoming AC power leads, or (2) direct replacement models, which use existing fluorescent
ballasts and lamp-holders.
