EnviroLite T8 LED tube wrap lights with battery backup are the perfect solution for commercial lighting needs. Maintenance-free lithium-ion with test switch provides 90-minutes of emergency power. These light fixtures are designed to save energy and lower maintenance costs. The LED tubes included use 30% less power to produce the same amount of light as fluorescent fixtures. The LED lamps are a low maintenance solution that eliminates the need to replace wired ballasts and drivers because the power source is in the tube. Because it's LED, you will never hear the hum that fluorescent fixtures make. The tube lamps in this commercial lighting strip provide daylight white (5,000K CCT) light at 1,800 Lumens per LED lamp. EnviroLite uses quality LED chips that last for 50,000-hours of continuous use. The fixture and tubes come with a 5-year warranty. Fixtures are ETL listed and can be installed in damp locations. The T8 LED tube lamps are DLC listed to qualify for commercial lighting rebates and special incentives in certain areas.
