Luminaires and Fittings Light-emitting-diode Luminaires
GENERAL
This category covers surface- and recessed-lighting luminaires containing only light-emitting-diode (LED) light sources.
Luminaires are not intended for use with infrared or ultraviolet LED light sources unless so marked.
Luminaires that contain fluorescent lamps in combination with an LED light source are covered under Fluorescent Surface-mounted Luminaires (IEUZ), Fluorescent Recessed Luminaires (IEVV) and Light Diffusers and Lenses for Air-handling Luminaires, Fluorescent (IEWR).
Luminaires that contain high-intensity discharge lamps in combination with an LED light source are covered under High-intensity-discharge Surface-mounted Luminaires (IEXT) and High-intensity-discharge Recessed Luminaires (IEXZ).
Luminaires with an LED light source intended to be connected to a nonintegral power source rated 30 V ac (60 V dc) or less are covered under Low-voltage Lighting Systems, Power Units, Luminaires and Fittings (IFDR).
Luminaires with an LED light source connected to a nonintegral power source rated 15 V ac (30 V dc) or less and intended to be part of a low-voltage landscape lighting system are covered under Landscape Lighting Systems, Low Voltage (IFDH).
Luminaires with an LED light source intended for connection only to a 24 V or less input and for use in recreational vehicles are covered under Low-voltage Luminaires for Recreational Vehicle Use (IFDQ).
Luminaires and Fittings
Recessed cooking hood luminaires are additionally marked with a minimum spacing marking: “INSTALL WITH MINIMUM SPACINGS BETWEEN A) CENTER-TO-CENTER OF ADJACENT LUMINAIRES: ___INCHES; B) TOP OF LUMINAIRE AND AN OVERHEAD BUILDING MEMBER: ___INCHES; AND C) LUMINAIRE CENTER TO SIDE BUILDING MEMBER:___INCHES.” The recessed cooking hood is intended to be installed in a hood that maintains these minimum spacings.
Air-handling Luminaires — Luminaires suitable for air handling use are marked “SUITABLE FOR AIR HANDLING USE.” For information on the use of air-handling luminaires in fire-rated ceiling constructions, reference should be made to the design information section under Fire Resistance Ratings (BXUV). For applicable requirements covering air-handling installations, reference should be made to ANSI/NFPA 90A, “Installation of Air-Conditioning and Ventilating Systems.”
Some recessed air-handling luminaires are restricted to certain applications because of certain features and are marked as follows: “VENTILATING OR COOLING AIR ONLY,”“ONLY FOR USE IN CEILING PLENUM OF NONCOMBUSTIBLE CONSTRUCTION OR WITH AIR HANDLING PARTS THAT COVER VENT OPENINGS” or “INSTALL ONLY IN ENVIRONMENTAL AIR HANDLING SPACES WHERE A COMPLETE METAL ENCLOSED WIRING SYSTEM IS PROVIDED.”
Luminaires marked “DRY LOCATIONS ONLY” are intended to be installed in indoor dry locations.
Luminaires marked “SUITABLE FOR DAMP LOCATIONS” are intended to be installed in damp or dry locations.
Luminaires marked “SUITABLE FOR WET LOCATIONS” are intended to be installed in wet, damp or dry locations.
The locations are defined in Electrical Equipment for Use in Ordinary Locations (AALZ) and the NEC.
In addition to the dry-, damp- or wet-location markings, a luminaire may be optionally investigated and marked for ingress protection in accordance with IEC 60529, “Degrees of Protection Provided by Enclosures (IP Code).” IP code markings are supplemental and not intended to replace dry-, damp- or wet-location markings.
Luminaires investigated for or restricted to a particular mounting location for suitability to wet locations are additionally marked “SUITABLE FOR MOUNTING WITHIN 1.2 M (4 FT) OF THE GROUND,”“SUITABLE FOR GROUND-MOUNTED RECESSED,”“LIMIT RANGE OF ADJUSTMENT TO (instruction)” or “COVERED CEILING MOUNT ONLY.”
Luminaires investigated for or restricted to a particular mounting location are marked “WALL MOUNT ONLY,”“FOR CEILING MOUNTING ONLY” or “MOUNTING ORIENTATION” (such as “This End Up”).
Luminaires are marked with a supply wire temperature rating “MIN __C SUPPLY CONDUCTORS,” if intended for greater than 60°C supply wiring. Luminaires rated for over 90°C supply wiring are additionally marked “NOT FOR USE IN DWELLING.”
Luminaires that include an integral raceway intended to comply with Section 410.64(A) of the NEC are marked “SUITABLE FOR USE AS RACEWAY,” and are additionally marked to include the maximum number, size and type of conductors they are intended to accommodate. See Surface Metal Raceways (RJBT) for raceways that can be assembled and installed as lighting units.
Some luminaires are only suitable for use with specific lamp types and are so marked. However, luminaires are not investigated or intended for use with sun lamps.
Luminaires containing components that require the luminaire to be connected only to an alternating-current circuit are marked “60 Hz” or “AC ONLY.”
Luminaires designed for connection to a proprietary wiring system will specify the name and part number of the proprietary system and all cautionary or other markings required for the system. These systems are covered under Manufactured Wiring Systems (QQVX).
Luminaires designed for connection to other than nominal 120 V supply and/or a 2-wire branch circuit are marked to identify the voltage supply or type of branch circuit or both.
Emergency Lighting — Luminaires intended for simultaneous connection to normal and emergency power circuits, as well as luminaires with integral batteries for emergency illumination, are covered under Emergency Lighting and Power Equipment (FTBR).
Exit Lighting — Luminaires that illuminate an integral legend “Exit” and are intended for installation in accordance with the NEC and ANSI/NFPA 101, “Life Safety Code,” are covered under Exit Fixtures (FWBO).
Electric Signs — Products that illuminate an integral legend other than “Exit” are covered under Signs (UXYT).
Suntan Lamps — Lighting products that employ suntan lamps are covered under Sun and Heat Lamps (QPDY) or Personal Sun and Heat Equipment (QGRX).
Submersible Luminaires — Luminaires intended for installation under water in accordance with Article 680 of the NEC are covered under Submersible Luminaires (IFEV) if intended for decorative fountains and similar locations, or Luminaires and Forming Shells (WBDT) if intended for installation in swimming pools and similar locations.
[Luminaires and Fittings Certified for Canada] (Light-emitting-diode Luminaires Certified for Canada) Light-emitting-diode Surface-mounted Luminaires Certified for Canada
Ceiling-mounted luminaires include cord-, stem-, chain- and cable-suspended luminaires, in addition to outlet-box-mounted luminaires.
All ceiling- and wall-mounted luminaires are acceptable for mounting on an insulated ceiling or wall. Exceptions: (1) luminaires obviously not designed for ceiling use or if marked “WALL MOUNT ONLY” are not acceptable for mounting on ceilings, and (2) luminaires marked “NONCOMBUSTIBLE SURFACE ONLY.”
Luminaires intended for continuous-row mounting are marked “SUITABLE FOR CONTINUOUS ROW MOUNTING.”
