15Basic Service

Wait for the lamp to reach full brightness. Position the fixture so the light

shines on a flat, white surface.

If there is an off-center “hot spot,” the lamp is not centered in the reflec-

tor. Pull the hot spot into the center of the field with small adjustments of

one or more of the lamp-adjustment screws.

If the light is significantly brighter in the center of the field than it is at the

edge, the lamp is too far forward in the reflector. Pull the lamp in by turn-

ing all three screws clockwise 1/4-turn at a time until the light is evenly

distributed.

If the light is brighter around the edge than it is in the center, or if light

output is low, the lamp is too far back in the reflector. “Push” the lamp out

by turning the screws counterclockwise 1/4-turn at a time until the light is

bright and evenly distributed.

Replacing the main fuse

The holder for the main fuse is built in to the mains input socket. If the fuse blows repeat-

edly, refer the fixture for servicing by a qualified technician.

Never replace the fuse with

one of a different rating!

Unplug the mains cable from the input socket.

Pry open the fuse holder and remove the fuse.

Replace the fuse with one of the same type and rating. The fuse rating is

listed on serial number label on the end plate.

Close the fuse holder and replace the mains cable.
