  • SCOPE

    1 Scope

    1.1 This standard specifies the requirements applicable to field replaceable light-emitting diode (LED) light engines rated up to 347 volts (nominal) and provided with integral lamp bases of other than the screw, bayonet, or pin type configurations typically found on incandescent or fluorescent light sources.

    1.2 This standard does not cover:

    a)    LED devices that are integral components and which form a non-replaceable part of a luminaire, such that they cannot be tested separately from the luminaire;

    b)    LED lamps or light engines with screw, bayonet or pin-type bases, intended as replacements for incandescent or fluorescent lamps; or

    c)    LED light engines having a means of supply connection other than the lamp bases allowed by 1.1, such as custom wiring harnesses.

    1.3 This standard does not cover the holders, sockets, and the like to which these LED light engines are intended to be mounted. Such products are covered by UL 8754 / ULC-S8754.
