UL 8750

Light Emitting Diode (LED) Equipment for Use in Lighting Products

UL CSDS Proposal Edition 2 Published Date: April 19, 2019 Last Revision: August 01, 2024

Scope

087500-000000-000000

1 Scope

1.1 These requirements cover LED equipment that is an integral part of aLED luminaires or other lighting systemsequipment. These requirements cover components including LED drivers, controllers, arrays (modules), and packages as defined within this standard. These requirements also cover power sources that are integrated into LED luminaires or lighting systems for functions other than a LED driver (e.g., DALI bus power supply).

1.1.0 LED equipment covered by this standard are intended for operation in the visible light spectrum between 400 – 700 nm. Coherent light sources (e.g. laser sources) are not covered by this standard.

Exception No. 1: LED packages as described in Supplement SD may have applications other than general illumination and may operate outside of the visible light spectrum.

Exception No. 2: Special Use LED arrays as described in Supplement SJ have intended applications other than general illumination and may operate outside of the visible light spectrum.

1.1.1 Deleted

1.1.2 Deleted

1.1.3 These requirements do not cover LED controllers within the scopes of the following standards:

a) Standard for Safety for Plug-In Locking Type Photocontrols for Use with Area Lighting, UL 773, or
b) Standard for Safety for Solid-State Dimming Controls, UL 1472.

1.2 These lighting products are intended for installation on branch circuits of 600 V nominal or less in accordance with the National Electrical Code (NEC), ANSI/NFPA 70, and for connection to isolated (non-utility connected) power sources such as generators, batteries, fuel cells, solar cells, and the like.

1.3 LED equipment is utilized in lighting products that comply with the end-product standards listed below. The requirements in this standard are intended to supplement those in other end-product standards. Included are:

a) Electric Signs, UL 48,
b) Portable Electric Luminaires, UL 153,
c) Underwater Luminaires and Submersible Junction Boxes, UL 676,
d) Emergency Lighting and Power Equipment, UL 924,
e) Stage and Studio Luminaires and Connector Strips, UL 1573,
f) Track Lighting Systems, UL 1574,
g) Luminaires, UL 1598,
h) Direct Plug-In Nightlights, UL 1786,
i) Low Voltage Landscape Lighting Systems, UL 1838,
j) Self-Ballasted Lamps and Lamp Adapters, UL 1993,
k) Luminous Egress Path Marking Systems, UL 1994, and
l) Low Voltage Lighting Systems, UL 2108.

1.4 The requirements in this standard do not anticipate additional construction, performance and marking considerations for the following end-applications: LED equipment subject to weather (outdoor use), LED equipment installed in air handling spaces or in other environmental air spaces (plenums), LED equipment intended for Emergency Lighting and Power Equipment, LED equipment with integral batteries (and battery packs), and LED equipment used in fire rated installations. LED equipment with such end-applications is subject to additional evaluation per applicable standards.
