The lamp life given by the manufacturer must never be exceeded. This is why you need to take notes on the
operational time of the lamp or check the operating hour meter (if available) regularly and replace the lamp in
time.
Keep exchanged lamp in a protective container and remove accordingly.
During the operation, the lamp reaches temperatures of up to 600° C.
Before replacing the lamp, unplug mains lead and let the lamp cool down (approx. 10 minutes).
During the installation do not touch the glass-bulbs bare-handed! Please follow the lamp manufacturer's
notes!
Do not install lamps with a higher wattage! Lamps with a higher wattage generate temperatures the device
was not designed for. Damages caused by non-observance are not subject to warranty.
Procedure:
Step 1: Unscrew the fixation screws X, Y of the lamp system and carefully remove it from the housing.
Step 2: If replacing the lamp, remove the old lamp from the lamp holder.
Step 3: Insert the lamp into the lamp holder.
Step 4: Replace the lamp system in the housing and tighten the fixation screws.
Step 5: Adjust the lamp as described under lamp adjustment.

The lampholder is aligned at the factory. Due to
differences between lamps, fine adjustment may
improve light performance.
Strike the lamp, open the shutter and the iris, set the
dimmer intensity onto 100 % and focus the light on
a flat surface (wall). Center the hot-spot (the
brightest part of the beam) using the 3 adjustment
screws "A, B, C". Turn one screw at a time to drag
the hot-spot diagonally across the projected image.
If you cannot detect a hot-spot, adjust the lamp until
the light is even.
To reduce a hot-spot, pull the lamp in by turning all
three screws "A, B, C" clockwise ¼-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 "A, B, C" counterclockwise ¼-turn at a
time the light is bright and evenly distributed.
