PERMITTED IN BOX,’’ have been evaluated for any heat contribution
added by branch circuit conductors.
Luminaires which, by their construction, do not permit access to or
inspection of field wiring connections from the front of the luminaire,
after installation, are marked ‘‘ACCESS ABOVE CEILING REQUIRED’’
or ‘‘ACCESS BEHIND WALL REQUIRED.’’
Luminaires that are provided with polymeric recessed housings are
marked ‘‘FOR USE IN ONE- AND TWO-FAMILY DWELLINGS ONLY’’
and ‘‘FOR USE IN NON-FIRE RATED INSTALLATIONS.’’
Luminaires that consist of (1) a luminaire housing and trims or (2) a
rough-in section and finishing sections are marked on each separable part
with correlation markings:
(1) For luminaire housing and trims, the housing is marked ‘‘USE
WITH (manufacturer’s name) (catalog number) TRIMS’’ and each trim
is marked with the manufacturer’s name and catalog number;
(2) For rough-in and finishing sections, the rough-in section is marked
in combination with the Listing Mark, ‘‘ROUGH-IN SECTION FOR USE
WITH FINISHING SECTION,’’ where the blank spaces are filled in with
a) type or catalog number or b) refers to the type or catalog number
located elsewhere on the label. The finishing section is marked in the
same manner stating ‘‘FINISHING SECTION FOR USE WITH
ROUGH-IN SECTION.’’
Luminaires that consist of separate wired luminaire sections are marked
on each separable part with correlation markings.

in Ordinary Locations (AALZ).
REQUIREMENTS
The basic standard used to investigate products in this category is UL
1598, ‘‘Luminaires.’’
UL MARK
The Listing Mark of Underwriters Laboratories Inc. on the product is
the only method provided by UL to identify products manufactured
under its Listing and Follow-Up Service. The Listing Mark for these products includes the name and/or symbol of Underwriters Laboratories Inc.
(as illustrated in the Introduction of this Directory) together with the
word ‘‘LISTED,’’ a control number, the product name ‘‘Luminaire,’’ and
one of the following words adjacent to the Listing Mark: ‘‘Recessed Incandescent,’’ ‘‘Recessed Incandescent Type IC,’’ ‘‘Rough-In Section for
Recessed Incandescent,’’ ‘‘Rough-In Section for Recessed Incandescent
Type IC’’ or ‘‘Finishing Section for Recessed Fixture.’’
Incandescent Recessed Luminaires (IEZX)
GENERAL
This category covers luminaires for installation in recessed cavities in
walls, ceilings and similar locations in accordance with the National Electrical Code, Section 410-64.
SPECIAL USE LUMINAIRES
Recessed type luminaires suitable for optional use with infrared heating
lamps are marked and rated for 250 watt reflector type lamps. Recessed
units suitable only for use with one or more infrared heating lamps are
Listed under Air Heaters, Room, Fixed and Location-Dedicated (KKWS) in
the Electrical Appliance and Utilization Equipment Directory.
TYPES OF RECESSED LUMINAIRES
TYPE IC LUMINAIRE — Luminaires marked ‘‘TYPE IC’’ may be
installed such that insulation and other combustible materials are in contact
with, and over the top of, the luminaire. Type IC luminaires are provided
with thermal protection to deactivate the lamp should the luminaire be mislamped.
INHERENTLY PROTECTED LUMINAIRE — A recessed luminaire which
does not exceed temperatures greater than 90C on outside surfaces even
when covered with insulation and mislamped or overlapped is identified by
being marked ‘‘INHERENTLY PROTECTED.’’
TYPE NON-IC LUMINAIRE — Recessed luminaires, except those identified as Type IC or for use in concrete only, are intended to be installed in an
uninsulated or insulated ceiling (or wall), with all insulation kept a minimum distance of 3 inches from the sides of the luminaire and not placed
over the luminaire such that it would entrap the heat produced by the luminaire. Other combustible materials are spaced, except at the points of support, at least 1/2 inch from the luminaire.
Type Non-IC luminaires are provided with thermal protection to deactivate the lamp(s) should insulation be placed over or in contact with the
luminaire.
For proper heat dissipation, Type Non-IC luminaires are intended to be
installed in a cavity as follows: If not marked with any spacing information,
the luminaire is intended to be installed not closer than 1/2 inch from any
surface forming the cavity behind the recessed portion of the luminaire and
not closer than 1 inch from adjacent luminaires.
Luminaires intended for marked spacing installation are marked
‘‘INSTALL WITH MINIMUM SPACINGS BETWEEN A) CENTER-TOCENTER OF ADJACENT LUMINAIRES: ___ INCHES; B) TOP OF LUMINAIRE AND AN OVERHEAD BUILDING MEMBER: ___ INCHES; AND
C) LUMINAIRE CENTER TO SIDE BUILDING MEMBER: ___ INCHES.’’
The marked spacing luminaire is to be installed in a cavity that maintains
these minimum spacings.
Individual obstructions, such as ceiling joists, barriers to maintain thermal
insulation 3 inches from the luminaire and other structural support members may be in the cavity area above the luminaire provided (1) they are not
closer than 1/2 inch from any part of the luminaire (except for points used
in support of the luminaire), and (2) they do not seal off the luminaire from
the remaining portion of the cavity. More than one marked spacing luminaire may be installed in the same cavity provided the marked spacings are
maintained from each luminaire to cavity sidewalls and to adjacent luminaires. Spacings between adjacent luminaires are measured center to center,
based upon the geometric center of the luminaire at the ceiling line.
CONCRETE ONLY LUMINAIRE — A recessed luminaire that is
exempted from being thermally protected because it is intended for use only
in a fire-resistant medium is marked ‘‘FOR USE IN CONCRETE ONLY.’’
A Type IC or Non-IC luminaire that is sealed to prevent the entry of concrete may be installed in concrete providing it is marked ‘‘SUITABLE FOR
USE IN POURED CONCRETE.’’
SUSPENDED CEILING LUMINAIRE — All recessed luminaires except
those marked for use in concrete only are suitable for use in suspended ceilings and may be marked ‘‘SUITABLE FOR SUSPENDED CEILING.’’
Recessed luminaires intended for use in suspended ceilings and provided
with integral clips are marked for use with particular grid systems. When
installed in accordance with this marking they comply with 410-16(c) of the
NEC. Instructions for using clips to secure the luminaire to the grid are provided with the luminaire. The ability of these clips to withstand seismic disturbances has not been evaluated.
GROUND-MOUNTED RECESSED LUMINAIRE — A ground-mounted
recessed luminaire that is exempted from being thermally protected because
it is intended for use only in a fire-resistant medium is marked ‘‘SUITABLE
FOR GROUND-MOUNTED RECESSED ONLY.’’
Incandescent Recessed Luminaires,
Convertible, Non-IC/IC (IFAH)
This category covers luminaires for installation in recessed cavities in
walls, ceilings and similar locations in accordance with the National Electrical Code, Section 410-64.
These products may be installed in either IC or Non-IC applications.
The same rough-in section or luminaire housing is used for both IC and
Non-IC applications. The choice of finishing section/trim and light source
(lamp) determine whether the completed luminaire is suitable for Type IC
installations or Non-IC installations.
Details for making the proper choice of finishing section/trim and lamp
appropriate for the application are contained in the installation instructions packaged with the rough-in section/luminaire housing. All luminaires employ a thermal protective device to deactivate the lamp(s) in the
event increased temperature conditions result where the installation
instructions are not followed.
TYPE IC INSTALLATIONS — Refer to Incandescent Recessed Luminaires (IEZX) sections entitled ‘‘Type IC Luminaires.’’
TYPE NON-IC INSTALLATIONS — Refer to Incandescent Recessed
Luminaires (IEZX) sections entitled ‘‘Type Non-IC Luminaires.’’
LUMINAIRE INSTALLATION MARKINGS
The rough-in section or the luminaire housing of a convertible recessed
luminaire is marked with the following two statements:
