LIGHT EMITTING DIODE (LED) LIGHT SOURCES FOR USE IN LIGHTING PRODUCTS

1 Scope
1.1 These requirements specify the minimum safety requirements for the component parts of a light emitting diode (LED) light source that serves as the source of illumination in any of the lighting products listed in 1.3.

1.2 An LED light source consists of one or more of the following component parts:

a)    LED or LED array - that provide illumination,

b)    Power source that supplies the proper voltage and current to operate the LEDs,

c)    Control circuitry that may switch, dim or otherwise control the electrical energy to the LEDs.

1.3 LED light sources complying with these specifications are utilized as the source of illumination in lighting products that comply with the appropriate end product standard as listed below. These lighting products are intended for installation on branch circuits of 600 V nominal or less in non-hazardous locations in accordance with the National Electrical Code (NEC), ANSI/NFPA 70. These requirements also apply to LED light sources connected to isolated (non-utility connected) power sources such as batteries, fuel cells, and the like. Included are:

a)    Luminaires, UL 1598;

b)    Portable luminaires, UL 153;

c)    Stage and studio luminaires, UL 1573;

d)    Submersible luminaires, UL 676;

e)    Swimming pool luminaires, UL 676;

f)    Track lighting systems, UL 1574 ;

g)    Signs, UL 48;

h)    Emergency lighting and exit signs, UL 924;

i)    Self-ballasted lamps, UL 1993;

j)    Luminous Egress Path Marking Systems, UL 1994;

k)    Nightlights, UL 1786;

l)    Flexible lighting, UL 2388;

m)    Low Voltage Lighting Systems, UL 2108;

n)    Lampholder Fittings, UL 496; and

o)    Landscape Lighting, UL 1838.

1.4 Applications incorporating LED light sources such as lighting products for use in hazardous locations, health care, emergency lighting or marine lighting have additional requirements not described in this outline of investigation.
