Lamp Adjustment
You can adjust the lamp’s position by turning the screws A, B, C.
The lamp position is set in the factory. As the lamps, which can be used, differ from manufacturer to
manufacturer, it can be necessary to readjust the position. The lamp must be readjusted e.g., if the light
does not seem to be evenly distributed within the ray of light.
Ignite the lamp and focus the ray of light on an even surface (wall). As the optimal distance between the
lamp and the lens was already set during the installation with screw "A", only the "Hot Spot" ( the brightest
part of the ray of light) must be centered. Turn in addition screw "B" and “C”. If the Hot Spot appears too
bright, you can weaken its intensity, by moving the lamp closer to the reflector. Turn in addition screw "A",
until the light is evenly distributed. If the light at the outside edge of the ray of light appears brighter as in the
center, the lamp is too close to the reflector. In this case move the lamp away from the reflector, until the
light is evenly distributed and the ray of light appears bright enough.
Adjusting beam angle
The Fresnel lens system can be configured in the range between 8 and 22 .To set the desired beam angle,
and loose 2 adjusting screws on the Fresnel lens unit and adjust the required beam angle.
Tighten the adjusting screws again and fix back the front cover.
