Marking and Application Guide
These luminaires are also intended to be installed with the top of the lens not less than 18
inches below the normal water level, unless otherwise marked. These luminaires are
intended for installation in permanently installed luminaire housings (forming shells) in which
the luminaire will be completely surrounded by water in the normal installation. These
luminaires are marked to indicate the proper luminaire housing or housings with which they
are to be used, and the luminaire housings are marked to indicate the luminaire or
luminaires with which the housing is to be used. These luminaires are provided with a
factory-installed, permanently attached flexible cord that extends at least 12 feet outside the
luminaire enclosure. This permits the luminaire to be removed from the luminaire housing
and lifted to the pool or spa deck for servicing without lowering the water level or
disconnecting the luminaire from the branch-circuit conductors. Luminaire housings that are
intended to be used with luminaires provided with a No. 12 AWG or larger, Type SJ, SJT or
SJTO flexible cord are marked for use with 3/4-inch or larger conduit. It is not intended that
conduit reducers and conduit with a trade size less than the size accommodated by the
threaded hub of the luminaire (fixture) housing be used.
No-Niche Luminaires. These luminaires are intended for permanent installation only in the
wall of a swimming pool or a field-fabricated spa, unless accompanying installation
instructions describe the option of installation in the bottom of the pool or spa. These
luminaires are also intended to be installed with the top of the lens not less than 18 inches
below the normal water level, unless otherwise marked. In addition, these luminaires are
intended to be mounted to a bracket that is permanently secured in or on the wall where the
luminaire will be completely surrounded by water. These luminaires, like wet-niche types,
are provided with a factory-installed, permanently attached flexible cord that extends at least
12 feet outside the luminaire enclosure. The luminaires are marked with an identification of
the mounting brackets for which they are suitable. The mounting brackets are also marked
with an identification of the luminaires for which they are suitable.
Convertible Underwater Luminaires For Aboveground Swimming Pools. These
luminaires are initially configured as underwater luminaires for aboveground storable
swimming use (see Storable Swimming Pool section). They include provisions for the one-
time field conversion of the luminaires to underwater luminaires for aboveground non-
storable swimming pool use. Once converted, these luminaires are not suitable for
modification back to their original configurations.
Fiber-Optic Underwater Luminaires. These luminaires consist of a lamp/electrical
enclosure that is intended to be permanently mounted not less than 5 feet from the pool or
spa wall and has a fiber-optic element and associated fittings to transmit the light to the pool
or spa. The lamp/electrical enclosure is intended to be installed above the level at which
water splashed from the pool or spa or from another source may collect.
Metal Conduit Only. A swimming pool luminaire housing (forming shell) for a wet-niche
luminaire and a mounting bracket for a no-niche luminaire that is not provided with a
grounding terminal for the supplemental No. 8 AWG grounding conductor that is required
when non-metallic conduit is used is marked ―CAUTION
— For proper grounding use only with metal conduit.‖
Orientation, Luminaire. A swimming pool luminaire that depends on its location or position
to function correctly is marked to indicate the way it is to be installed or used, unless the
position is obvious.
