Installation Instructions (Recessed Mount)
Sigma Small and Sigma Large
come with mounting springs
installed. If your application
requires a screw-mount
installation, you will need to
remove the springs. This can be
done by first squeezing the coils
together and then angling the free
side up and away from the spring
retaining tabs. (See Figure 1)
1. If this is a new installation (i.e. no existing hole), then cut a
hole in the mounting surface according to the cutout diameter
required for the light (see chart on page 3). If this is a refit (i.e.
an existing hole), proceed to the next step.
2. Connect the light to a low voltage power source following the
wiring instructions in the next section of this guide.
3. Once all electrical connections are made and secure, proceed
accordingly:

PHYSICAL INSTALLATION
Whether the lights are installed using the springs provided or
by screw-mounting, it is imperative that the lights be mounted
in such a location that the fixtures are protected from the rear
against water exposure.
Also, it is important that the lights are mounted with airspace
around the heat sink housing to allow for convective cooling
of the lights. For recessed applications (this does not apply for
surface-mount installations), we recommend a distance of ½”
(13mm) of free space above the housing.

B. Screw-Mount Version (Small or Large): Twist and remove
the trim ring on the Sigma and insert it into the cutout hole in
the mounting surface. Fasten with three #4 flat head screws
(see Figure 3). Place the trim ring over the light making sure
the tabs of the trim ring engage with the openings in the
housing. Twist the trim ring on to secure it.

A. Spring-Mount Version (Small or Large): With trim ring
attached, gently bend back the mounting springs on the
Sigma and insert the spring tips into the cutout hole in the
mounting surface (see Figure 2).
