4. Installation
4.1Fitting/Exchanging the lamp
DANGER !
Install the lamps with the device switched off only.
Unplug from mains before !
To insert the lamp (MSD/HSD 250 GY-9,5 or MSD 250/2, GY-9,5) open the housing by loosening the fastening
screws at the side panels and by removing the focus-screw and zoom-screw.
If changing the lamp, remove the old lamp from the socket. Insert the new lamp to the socket.
Do not install a lamp with a higher wattage! A lamp like this generates temperatures the device is not designed for.
Damages caused by non-observance are not subject to warranty. Please follow the lamp manufacturer‘s notes!
Do not touch the glass-bulb bare hands during the installation! Make sure that the lamp is installed tightly into the
lampholder system.
Adjust the optimal distance 1-1.5 mm from the lens by turning the screw „A“ (see the drawings „Lamp adjustment“
below).
Replace the housing cover and tighten the screws.
Do not operate this fixture with opened housing-cover!
4.2 Lamp adjustment
Correct Incorrect
The BEAM 250 XT lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may
improve light performance.
Strike the lamp and focus the light on a flat surface (wall). As the optimum distance of lamp from lens was
adjusted during the installing or changing the lamp (by turning the screw „A“), it is necessary to adjust only the
second position by turning the screw „B“, in order to center the hot-spot (the brightest part of the beam).
If the Hot Spot seems to be too bright, you can lower its intensity by moving the lamp closer to the reflector. Do
so by turning srew „A“ until the light is evenly distributed.
If the light on the edge seems to be brighter as in the center, the lamp is too close at the reflector. In this case, you
need to move the lamp away from the reflector until the light is evenly distributed and the beam appears bright
enough.
Keep optimum
distance to lens!
