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.
