Keystone - Since 1945Keystone Direct Drive LED T8 tube lights can be utilized in fixtures that currently have fluorescent lighting: Commercial/Office Space Retail InstallationsHospitals Airports and Train Stations Residential Installations Food Service Locations Schools and Cold Storage. The lumen output of an LED T8 tube is different than that of the more familiar fluorescent T8 lamp. Fluorescent lamps deliver lumens in a 360° pattern, where many of the lumens are wasted because they are directed upwards. With LED T8 tube lights, the delivered light is more directional, so fewer lumens are required to achieve similar or greater levels of usable light output.

NSFThis series of Keystone LED tube lights has frosted lens to eliminate pixelation and shatterproof coated glass making them ideal for food service, residential and school applications. These Dimmable LED tubes have earned certification from NSF International for installation in food processing environments and locations with similar sanitation requirements. Keystones Direct Drive LED tubes eliminate the need for an external driver or ballast. Its as easy as changing a light bulb. Simply remove the existing T8 fluorescent lamps and replace with Keystone Direct Drive LED tubes. No special instructions, no tools. The LED tubes simply run off the existing instant or program start electronic ballast. Energy efficiency in an instant. Making your retrofit project even easier, Keystone offers a four (4) socket, non-shunted wiring harness - complete with the quick disconnect connectors.
