"Offering the versatility of single or double ended wiring options in one
product SKU, this LED UL Type-B T5 lamp is an easy retrofit into most
common linear fluorescent fixtures with shunted or non-shunted lamp
holders (see re-lamping examples provided). In addition to flexible
installation features that save installers time and money, the SingleEnded/
Double-Ended LED T5 lamp consumes up to 50% less energy than standard
fluorescent tubes, providing facilities with long-term operational savings."
