Keystone’s DirectDrive DX2 is a UL Type B line voltage tube offering single or double ended wiring options, allowing you to hold less inventory. In addition, DX2 utilizes both shunted and non-shunted lamp holders, making it an easy LED replacement for T8 fluorescent tubes. These T8 LED tubes can provide up to 50% more energy savings than standard F32T8 lamps. Since LED tubes have a longer useful lifespan than their fluorescent counterparts, DX2 will also reduce maintenance costs. Select DirectDrive DX2 tubes are now available in Made in America options. These tubes offer the same single- or double-ended wiring versatility while meeting with BAA and TAA standards.

Keystone's LED T8 Tube Light allows you to use single-ended wiring with non-shunted sockets or double-ended wiring with the use of either shunted or unshunted lamp holders. This Made in America tube also has an isolated integral driver that eliminates the need for external drivers or ballasts. Replacing your conventional fluorescent lamp these LED T8 have approximate 40% more energy efficient than the standard F32T8 Lamp. With an operating temperature of -20 degrees Celsius/-4 degrees Fahrenheit to 45 degrees Celsius/113 degrees Fahrenheit these lamps are great for use in residential, commercial, retail displays, hotel, motel and resort applications.
