UL 8750:2017 Light Emitting Diode (LED) Equipment for Use in Lighting Products.
1.1 These requirements cover LED equipment that is an integral part of a luminaire or other lighting equipment and which operates in the visible light spectrum between 400 — 700 nm. These requirements also cover the component parts of light emitting diode (LED) equipment, including LED drivers, controllers, arrays, modules, and packages as defined within this standard.
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) SeIf-Ballasted Lamps and Lamp Adapters, UL 1993,
k) Luminous Egress Path Marking Systems, UL 1994, and
l) Low Voltage Lighting Systems, UL 2108.
2 General
2.1 Components
2.1.1 Except as indicated in this clause, a component of a product covered by this standard shall comply with the requirements for that component. See the Standards for Components appendix for a list of standards covering components generally used in the products covered by this standard.
2.1.2 A component is not required to comply with a specific requirement that:
a) Involves a feature or charactenstic not required in the application of the component in the product covered by this standard, or
b) Is superseded by a requirement in this standard.
2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use.
2.1.4 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions.
2.2 Units of measurement
2.2.1 Except for conductor size, values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information.
2.2.2 All values of voltage and current are true root mean square (rms) values unless otherwise indicated.
2.2.3 For customary purposes wire sizes are in American Wire Gauge (AWG).
2.3 Reference publications
2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.UL 8750 pdf download.
