We opened the back end of
the fixture to expose the AC
wiring.
Power to
circuit board

On/Off switch
For our
experimentation
purposes we broke out
the wiring in order to
measure voltage and
current.
120V, 60Hz, 4.2A UL listing
Positive
to lights
Neutral
to lights
Power to circuit board
Added wiring from power supply on
back of circuit board to manual
toggle switch
This is the
sensor circuit
board.
Infrared light impinges
the sensor through a
diffuser lens. Changes
are interpreted as
motion.

Wiring added to power supply for on/off toggle
Relay
With our
breakout box
we can
measure
differences
between
incandescent,
CFL and LED
