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.

Summary of Topics

This revision to UL 8753/ULC-S8753 is being issued to update the title page to reaffirm approval as an American National Standard and as a National Standard of Canada. No changes in requirements have been made.

There are national differences only where standards (U.S. vs. Canadian) are referenced. However, the body of the standard is technically identical for Canada and the U.S.
