Dual Light Level Control
Light comes on half bright for selected time after dusk
(Off, 3 hr., 6 hr., until dawn). If motion is sensed, the
light turns on full bright for the ON-TIME (1, 5, or 20
minutes) then returns to dim mode.

For under eave installation, the sensor head must
be rotated as shown in the next two steps for proper
operation and to avoid the risk of electrical shock.
For eave mount only:
❒ Swing the sensor head towards the clamp screw
joint.

MOUNT THE LIGHT CONTROL.
❒ Align the Light Control cover plate and cover plate

❒ Align the three slots in the decorative shell with the
lamp holder pins. Push the shell in and then twist
clockwise to lock. Repeat for other shell.

❒ Push the Rubber Plug firmly into place.
❒ If a wet location junction box was not used, caulk the
wall plate mounting surface with silicone weather
sealant.
To avoid water damage and
electrical shock, keep lamp
holders 30° below horizontal.
WIRE THE LIGHT CONTROL.
❒ Turn power off at the fuse or circuit breaker.
❒ Remove the existing light fixture.
❒ Install the mounting strap as shown using two
screws that fit your junction box.
❒ The plastic hanger can be used to hold the fixture
while wiring. The small end of the plastic hanger
can be threaded through the hole in the center of the
cover plate. The small end then goes into one of the
slots on the mounting strap.
❒ Route the Light Control’s wires through the large
gasket holes.
❒ Twist the junction box wires and fixture wires together
as shown. Secure with wire connectors.
Keep lamps at least
1" (2.5 cm) from the

TEST AND ADJUSTMENT
❒ Turn on the circuit breaker and light switch.
NOTE: Sensor has about 1 1/2 minutes warm up
period before it will detect motion. When first
turned on, wait about 1 1/2 minutes.
❒ Turn the RANGE control to the mid position,
DUAL LIGHT LEVEL to OFF, and the ON-TIME
control to the TEST position.

Avoid aiming the control at:
• Objects that change temperature rapidly, such as
heating vents and air conditioners. These heat
sources could cause false triggering.
• Areas where pets or traffic may trigger the control.
• Nearby large, light-colored objects reflecting light
may trigger the shut-off feature. Do not point other
lights at the sensor.
