The SpectraLight III diffuser is shipped in a separate container and must be installed next.
14. Carefully unpack and remove the diffuser from its shipping container.
Make sure the hinge pins are carefully placed behind the Horizon lamps to avoid lamp breakage.
15. Insert the diffuser hinge pins into the front of the slotted receptacles located at the bottom rear corners of the
luminaire housing. The smooth side of the diffuser should face the interior of the luminaire, and the textured side
should face out, to the interior of the booth. Refer to Figure 8.

16. Rotate the diffuser to its closed position and secure it in place with the latch.
Ensure that the diffuser latch is secured before releasing. Failure to do so may result in the
diffuser sliding out of position.
17. Plug SpectraLight III into a power source matching the voltage specified on the power label on the rear of the unit.
Turn on the Main Power Switch located on the front panel.
Note: Immediately upon power up, the unit will go through a brief system test to ensure that the voltage and electrical
line are satisfactory. Testing Line appears in the front panel display. The incandescent lamps will be powered during the
test. Once the test is complete, the unit is ready for operation
