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. This standard contains requirements that supplement the luminaire requirements contained in the Standard for Luminaires@ UL 1598@ that apply to the retrofit kit and the luminaire. 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. This standard 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. This standard 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.
