Keystone Direct Drive X2 Tubes – Single End or Double End Line Voltage


Ballast bypass LED T8 lamps have become the most popular option for retrofitting linear fluorescent bulbs. But what hasn’t been decided yet is which install method is preferred, single-end wiring or double-ended? Better yet, what if there was an LED T8 that could do both? With Keystone’s release of the Direct Drive X2 LED T8, that option has become reality.

Initially Keystone like many manufacturers developed their Type B LED T8, the Direct Drive, to be single-end wire only. This means that if you had a fluorescent T8 fixture, you would need a new non-shunted socket to re-wire one side of that fixture. There were some options on the market however that offered double-end wiring for their ballast bypass tubes, which allowed the installer to utilize the existing sockets that were previously used in the fluorescent system. This was a good option for those who had existing sockets that were in good shape and would help save on install costs. Keystone saw an opportunity on the market and the X2 was born.

Other than having both choices for install, just about everything else about these lamps is similar to the Direct Drives previously out. The same high efficacy on just 15W for 4′ and 7W for 2′. Available in 3000K all the way up to 6500K.
