1.1 These requirements apply to light-emitting diode (LED) retrofit luminaire conversion kits that are
intended to replace existing light sources and systems including incandescent, fluorescent, induction, and
high intensity discharge (HID) light sources in previously installed luminaires that already comply with the
requirements in the Standard for Luminaires, UL 1598. The kits are intended for use on:
a) Luminaires where specific luminaire model or part numbers are identified in the kit
installation instructions; or
b) One or more generic type luminaires that meet specific criteria identified in the installation kit
instructions.
1.2 This outline of investigation contains requirements that supplement the luminaire requirements
contained in the Standard for Luminaires, UL 1598 that apply to the retrofit kit and the luminaire.
1.3 LED retrofit kits covered by these requirements include but are not limited to LED lamps and arrays,
LED control modules, LED drivers, LED power supplies, wiring, lampholders, brackets, wire connectors,
reflectors, diffusers, and other associated mechanical, electrical, or optical devices.
1.4 This outline of investigation does not cover luminaire reflector kits covered by the Standard for
Supplemental Requirements for Luminaire Reflector Kits for Installation on Previously Installed
Fluorescent Luminaires, UL 1598B.
1.5 This outline of investigation does not cover luminaire conversion lamps that are intended to replace
existing lamps without any modification, rewiring, or component replacement in the luminaire other than
direct replacement of the lamp using the existing lampholder. Requirements for these direct replacement
lamps are specified in the Standard for Self-Ballasted Lamps and Lamp Adapters, UL 1993.
1.6 This outline of investigation does not cover luminaire conversion retrofit kits for amateur movie lights;
aquarium lights, cabinet lights, decorative lighting strings, combination fan/IR lamps used for heating,
electric signs, exit signs, junction boxes for swimming pool fixtures, lamp adapters, low-level path marking
and lighting systems, low-voltage landscape lighting, low voltage lighting fixtures for use in recreational
vehicles, low voltage marine lighting, luminairs for hazardous locations, luminaires for recreational
vehicles, marine navigational lights, marine-type fixtures, portable electric displays, portable hand lamps, portable luminaires, portable sun/heat lamps, self-ballasted lamps and lamp adapters, stage and studio
luminaires, submersible luminaires, swimming pool luminaires, temporary lighting strings, therapeutic
lamps, track lighting systems, under-cabinet lights and cord-connected under-cabinet lights and unit equipment for emergency lighting.
