UL Type C Lamps

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 employ lamp holders to connect to the fixture being retrofitted, do not operate utilizing the existing fluorescent ballast, and require rewiring of the existing fixture to replace the ballast with an external driver. The lamp holders are then wired to receive only the low-voltage electricity that is supplied by that external driver. (See Testing and Reporting Requirements for Linear Replacement Lamps for more detail on testing requirements.) Please note reference to UL type is derived from UL 1993, 4th edition, 2012-12-04 Section SA6.13.1.
