Two-foot, three-foot, four-foot, eight-foot, and U-bend LED “tubes” designed to replace two-foot, three-foot, four-foot, eight-foot, and U-bend fluorescent lamps, respectively. Products in this category operate utilizing the existing fluorescent ballast and also have the ability to operate utilizing line voltage if the fixture is rewired to bypass the ballast. These products connect to the fixture using standard pin-base connections to the lamp holders. Note that due to testing considerations, at this time only products that operate utilizing specific ballast types are eligible. Please see the Testing Requirements for more detail. Replacement lamps designed to operate utilizing magnetic ballasts, or other types of electronic ballasts not specified, are not eligible at this time. Also note that products claiming to replace T12 lamps are not eligible under Dual-Mode primary use designations. Please note reference to UL type is derived from UL 1993, 4th edition, 2012-12-04 Section SA6.13.1.
