If feeding a wire through the knock-out at the back
of connection box, use silicone sealant to completely
seal between the back of the connection box and wall
surface to prevent water from seeping into the con-
nection box. The silicone sealant should be waterproof
& UV proof. If feeding a wire through a knock-out on
the side of the connection box the cable gland should
be used and installed as shown in
Fig. 5. Once the sealing gland is
installed the nut should be gently
tightened up against the gland
body to ensure the wire is secured
in place and no water can get into
the connection box.
Feed the A/C cable into the
connection
box
and
strip
approximately 1/4” of insulation
from each of the 2 conductors of
the A/C wire and attached to the
terminal block as shown in Fig.
6, black wire to black (hot) white
wire to white (neutral).
Make sure the waterproof seal to
the lid is in place (Fig. 7) and fasten
to the connection box using the 4
connection screws provided. In-
stall the provided screw covers. To
adjust the Mightylite simply hold
the connection box firmly while
moving the head of the floodlight
to the required position. If using
the “C” bracket, the junction box
can be swiveled to the desired
position and then the light head
can be further swiveled.

The Mightylite has three adjustment knobs as shown
in Fig. 8 to adjust the light level for activation, the
time duration of the light and the sensitivity of the IR
sensor.
The adjustment knob labeled “F” adjusts the outdoor
light level (LUX) required for the Mightylite to operate.
A setting of 1 requires complete darkness for the unit
to operate. A setting of 5 allows the unit to work in full
daylight.
The adjustment knob labeled “T” controls the time the
light will remain on once triggered. This adjustment
ranges from approximately 5 seconds to 10 minutes.
Turning the knob clockwise increases the time
duration.
The control labeled “R” changes the sensitivity of the
IR detector. This adjustment should be placed at mid-
range and then adjusted if you have false triggers or
light is not coming on when it should. Turning the knob
clockwise will increase the sensitivity of the sensor.

troubleShootIng
Lights won’t come on
• Power not on
Turn on indoor switch or check fuse.
• Wired incorrectly
Check wiring is the same as wiring diagram.
• PIR not detecting movement
Adjust the angle and direction of the PIR.
For best results walk across the beam.
• Light conditions too bright
Wait until light conditions are darker (at dusk)
or turn the LUX control up.
Lights stay on
• TIME set too high
Turn ‘Time’ knob towards ‘-’ end
(approximately 5 secs to 10 min adjustable).
• Wired incorrectly
Check wiring is the same as wiring diagram.
• Frequent changes in heat are being detected
Check sensing area for possible heat sources (e.g. air
vents, moving vehicles, moving trees) and re-position
the sensor or alter the RANGE control downwards.
Lights keep turning on and off (cycling)
• Changes in heat are being detected from a fixed heat source
Check the sensing area for air vents, light fittings or fans
and either re-position the sensor or adjust the aim.
• Changes in heat are being detected from a moving object
Check the sensing area for moving vehicles, animals,
pedestrians, moving trees and alter the aim of the sensor
accordingly.
• Light and heat are being reflected back onto the sensor
Alter aim of the sensor or paint the reflecting surface
with a dull finish.
• Sudden temperature changes due to storms or high winds
Turn sensor off until storm passes or install in a sheltered
location.
Sensor operates differently in hot and cold conditions
• Temperature differences are affecting the sensor’s sensitivity
Turn the sensitivity (RANGE) control knob toward the
MAXIMUM end for summer (hot conditions) and toward
MINIMUM for winter (cold conditions). This compensates
for variations in temperature.
