scope:

1.1 These requirements apply to light-emitting diode (LED) retrofit kits that are intended to retrofit existing light sources or other components in previously installed luminaires that already comply with one of the standards in 3.

1.2 These kits are intended for use with:

1. a) Luminaires where specific luminaire models or part numbers as identified in the kit installation instructions; or
2. b) One or more generic type luminaires that meet specific criteria identified in the kit installation instructions.

1.3 These kits are intended to retrofit the products covered by the following standards:

1. a) UL 1598A, Standard for Marine Luminaires,
2. b) UL 1573, Standard for Stage and Studio Luminaires,
3. c) UL 1598, Standard for Luminaires,
4. d) UL 2108, Standard for Low Voltage Lighting Systems,
5. e) UL 471, Standard for Commercial Refrigerators and Freezers, or
6. f) UL 60335-1, Standard for Household and similar electrical appliances - Safety - Part 1: General requirements, and UL 60335-2-89, Standard for Household and Similar Electrical Appliances - Safety - Part 2-89: Particular Requirements for Commercial Refrigerating Appliances and Ice-Makers with an Incorporated or Remote Refrigerant Unit or Motor-Compressor.

1.4 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.

1.5 The host luminaire is expected to have been designed and manufactured per the applicable standards for safety (See 3). The host luminaire is also expected to have been appropriately installed per manufacturer instructions and applicable installation codes.

1.6 Components of LED retrofit kits can include, but are not limited to, LED lamps, LED arrays, LED controllers, LED drivers, power supplies, wiring, lampholders, brackets, wire connectors, reflectors, diffusers, and other associated mechanical, electrical, or optical devices.

1.7 In this standard the installation instructions is considered a component of retrofit kits. The information provided in the installation instructions is considered critical for appropriate selection and proper installation of retrofit kits.

1.8 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.

1.9 Use of this standard to cover retrofit kits intended for product types other than those noted in 3 may require an additional investigation.
