The lamp orientation and optimization must be adjusted after every lamp change. This
procedure centers the lamp in the reflector. Proper optimization will increase lamp life
and ensure a bright crisp output. Improper optimization may add a yellow tint to the
lamp output and reduce intensity. The minimum deviation amount is 1.0mm. Running
the fixture within a lower deviation can cause damage to the lamp and/or lens.
The POWER WASH 250B™ lamp holder is aligned at the factory. However, due to
slight imperfections in all lamps, fine adjustments may improve light performance.
Please follow this procedure:
6.3.1 Strike the lamp (for example in the LAMP menu) and wait a while until full
intensity of the lamp.
6.3.2 Using either a DMX controller or the control panel on the unit, strike the lamp and
focus the light on a flat surface.(beam open, white, no gobo, no effects).
6.3.3 Center the hot-spot (the brightest part of the beam) using the 3 adjustment
screws. 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.
6.3.4 To reduce a hot-spot, pull the lamp in by turning all three screws clockwise 1/4-
turn at a time until the light is evenly distributed.
6.3.5 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
Attention: Be sure that the minimum distance between the lamp and lens is more then
1.0mm. If it is less then this distance, the lens has higher probability of shattering.
