LAMP INSTALLATION AND OPERATION
REMOVE THE REAR TOP COVER PLATE by releasing the four chromed captive
quarter-turn screws and lifting the plate from the top of the lamphouse enclosure. Loosen the two
thumbscrews(A)anddismountthestainlesssteelheatshieldtoexposethelampsocket(B&C).
DO NOT TOUCH the quartz portion
of the metal halide lamp with bare fingers! Any
fingermarksaccidentallyplacedonthelamp envelope
must be removed with alcohol before lighting the bulb;
skin oils will rapidly burn into the envelope material
and shorten lamp life. Wear clean cloth gloves or grasp
the envelope using a clean cloth towel when handling
the lamp. Make certain that the threaded brass adapter
(C)andthelongerofthetwoigniterleadsarefirmly
seated into the lamp support collet (B).
THE METAL HALIDE LAMP is
polarized(positive&negative)andthelargercathode
(-) end cap (D) screws into the adapter (C). Different
thread sizes insure that the lamp cannot be reversed.
The anode (+) end cap (E) includes a thumb nut.
SECURE THE LAMP by
grasping the cathode end cap by the knurled
surface and turning clockwise. Tighten

INSTALL THE RING TERMINAL at the end of the shorter of the two igniter leads
over the threaded pin of the anode end cap (E) and secure using the thumb nut supplied with the lamp.

connection of the end caps to the quartz envelope of the lamp. Replace the stainless steel heat shield
and the lamphouse top cover plate; secure all fasteners.
CHECK THE SPOTLIGHT DATA PLATE for the required input voltage. Plug the AC
cord from the spotlight into an appropriate AC outlet. Place the POWER switch in the “ON” position
and the lamp will ignite. The cooling fans in the power supply will start immediately, and the lamp
cooling fan will start after a 30 second delay. The delay will allow the lamp to reach its normal operating
temperature and intensity more rapidly.
