Clothes Closet Lighting
People don’t often think about the fire risks posed by the light in their clothes closet, but it’s one
of the few places in the house where a source of high heat can get too close to flammable materials. Lighting must
be installed safely with adequate separation from clothes, boxes and other flammables stored in the closet. Additionally,
the quality of the light, as well as bulb efficiency, will influence your lighting choices.
The
2009 International Residential Code (IRC) on "Permitted Luminaires and Clearance from Clothing"
The IRC defines a "luminaire" as follows: a complete
lighting unit consisting of a lamp or lamps, together with the parts designed to distribute the light, to position and protect
the lamps and ballast (where applicable), and to connect the lamps to the power supply.
Types of luminaires permitted by the 2009 IRC include:
- surface-mounted or recessed incandescent luminaires with completely enclosed lamps, surface-mounted
or recessed fluorescent luminaires; and
- surface-mounted
fluorescent or LED luminaires identified as suitable for installation within the storage area.
Luminaires not permitted by the 2009 IRC:
- Incandescent luminaires with open or partially enclosed lamps and pendant luminaires or lamp-holders
should be prohibited.
Clearances permitted
by the 2009 IRC:
The minimum distance between luminaires installed in clothes closets and the nearest
point of a storage area shall be as follows:
1. Surface-mounted incandescent or LED luminaires with a completely enclosed light
source shall be installed on a wall above the door or on the ceiling, provided that there is a minimum clearance of 12 inches
(305 mm) between the fixture and the nearest point of a storage space.
2. Surface-mounted fluorescent luminaires shall be installed on
the wall above the door or on the ceiling, provided that there is a minimum clearance of 6 inches (152 mm).
3. Recessed incandescent luminaires
or LED luminaires with a completely enclosed light source shall be installed in the wall or the ceiling, provided that there
is a minimum clearance of 6 inches (152 mm).
4. Recessed fluorescent luminaires
shall be installed in the wall or on the ceiling, provided that there is a minimum clearance of 6 inches (152 mm) between
the fixture and the nearest point of storage space.
5. Surface-mounted fluorescent
or LED luminaires shall be permitted to be installed within the storage space where identified within this use.
Also, metal pull chains may be dangerous; if the base cracks, the chain can become
electrified.
Color Rendering Index (CRI)
CRI is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully,
in comparison with an ideal or natural light source. The closer the CRI of a lamp is to 100, the more "true" it
renders colors in the environment. Poor CRI is the reason that a shirt and pants that seemed to match at home now clash
in the restroom at work. For clothes closets lighting, the CRI should be as high as possible. Incandescent lights are inefficient
but they have a CRI of 100, making them the most aesthetic lighting choice. Compact fluorescents lights (CFLs) are far more
efficient and have a longer life than incandescent bulbs, but they have a CRI in the low 60s, making them a poor choice for
clothes closet applications. Low-voltage halogen and LED lights are relatively efficient, long-lasting, and have a high
CRI, although not as high as incandescent bulbs.
In summary, homeowners should replace lighting in their clothes closets if the light
has the potential to ignite flammable materials in the closet.
