Caution:
Do not squeeze the lamp glass while removing the existing lamp
from the socket. Lamp glass may shatter.
6. Remove all packaging materials from the new lamp. Holding the new lamp by its
ceramic base, gently press the two base pins into the lamp socket until the lamp
is firmly seated.
Caution:
When handling the new lamp, avoid contact with the lamp glass.
If the lamp glass is soiled by oil or dirt from skin, gloves, etc.,
clean the cold lamp glass with an alcohol wipe. A soiled lamp
could overheat and burst, causing damage to the fixture.
7. Reinsert the lamp assembly straight into the fixture.
Caution:
Make sure the lamp socket wires are not wrapped around the
lamp or crimped while reinserting the lamp assembly.
8. Tighten the lamp assembly screws (A).
9. Reset the lamp hours to zero to track the lamp life, (see "Lamp HR/Strike Reset"
on page 3-27).
10. Optimize the new lamp.
Optimizing the Lamp
Optimize the lamp after replacement, or if there is a "hot spot" of brightness
anywhere other than the center of the light beam.
To complete the optimization procedure below, use either the fixture's on-board
menu system (see "Chapter 3: Fixture Operation" and "x.Spot®Xtreme Menu Map" )
or a DMX controller (see "Chapter 4: DMX Programming" and "Appendix A: DMX
Protocol" ).
1. Orient the fixture so that the beam will project onto a flat, white surface at least
10 feet (3 m) away.
2. Turn the lamp on. Ensure the light beam is round and not oval. If necessary,
adjust the pan and tilt construct values until the beam is round.
3. For x.SpotXtreme fixtures, adjust the focus until the edge of the light beam is
sharp.
4. Set the DIM (intensity) channel at full (DMX value of 255).
5. Set diffusion filters. DMX channel 21 (CTB) = 43. DMX channel 22 (CTO)= 0.
6. Locate the three lamp optimization screws (x, y, and z) shown in Figure 5-4.
7. Look at the wall where the beam is projected and use the optimization screws to
adjust the lamp's position within the fixture until the "hotspot" of brightness is at
the center of the beam and diffused. The x and y screws move the hotspot. The
center z screw adjusts beam flatness.
