3. LENSES
2.1
Disassembling the lamp casing / installing a lamp
Lamps that have been damaged, must be replaced immediately! Please proceed as follows to
replace the lamp:
+
The lamp gets very hot during operation of the spotlight, so let it cool down sufficiently
before you attempt to dismount it!
s
Disconnect the spotlight from the mains power supply, and unscrew the thumb screw on the
rear of the lamp casing
(G 9.5 socket).
s
Carefully pull out the lamp casing
from the rear part of the spotlight.
s
Carefully take the lamp out of its carton, by holding it at its socket:
+
Never touch the glass bulb of the lamp, as this can reduce the lamps service life
considerably. If you touch the glass bulb during installation, wipe it clean with a lint-
free cloth damped with ethyl alcohol (spirit).
s
Depending on socket type, use the corresponding temperature-resistant rubber adapter provided.
s
Press the lamp socket (and the rubber adapter) into the holder inside the lamp casing
until
the lamp is safely mounted in place. The entire bottom side of the lamp socket must be in
contact with the casing.
s
Remount the casing and connect it to the grounding cable
coming from the spotlight. Fasten
the thumb screw until the casing is safely mounted in place.
s
Avoid touching the reflector with bare hands. Oily finger marks can bake onto the glass surface
and substantially lower optical quality.

LENSES
Your ULTRAPAR spotlight is delivered with four glass lenses.
+
Never use your ULTRAPAR without the protective mesh in combination with the color
frame because it prevents direct contact with the hot lamp surface. It also prevents
pieces of broken glass from uncontrollably dispersing in the event of the lens being
broken.
The shape of each lens determines the light beam produced by the spotlight (Tab. 3.1). Also, use
the turnable lens ring to optimally adjust the direction of the light beam.
