Lamp Alignment
Due to slight variations between lamps it may be necessary to perform fine adjustments
to remove excessively dark or bright spots in the output field. The lamp holder is aligned
at the factory, large adjustments to the alignment will not be necessary. Excessively
bright spots can damage optical components.
1. Disconnect fixture from power and make certain lamp is cool.
2. Remove both the Top and Lamp covers (see Lamp Installation).
3. Turn Screw A located on the back plate of the Head, visually center the lamp
between the condenser lens and the reflector. Optimum distance between the
lamp and the condenser lens is 0.04”-0.06” (3/64”-1/16” or 1mm-1.5mm)
4. Turn Screw B, visually center the lamp horizontally to the lens.
5. After visually centering the lamp, replace both the Lamp and Top covers.
6. Apply power to the fixture. CAUTION: Double check for Lamp cover is installation.
7. Using a controller, strike the lamp with shutter and dimmer to 100% and project an
open white beam on a flat neutral colored surface.
8. Use Slight adjustment of
Screw B ONLY to optimize the hot spot of the beam
.
9. Extreme caution must be utilized when adjusting Screw A. The lamp must not
come to reset against either the front lens or reflector. If the edges of the beam are
brighter than the center, the lamp is too close to the reflector. If the center of the
beam is much brighter than the edges, the lamp is too close to the condenser lens.
Again, the lamp must not come to reset against either the front lens or reflector.
