2. The lampholder is an integral part of the
lamp access cover. See Figure 2. Remove
the two thumbscrews A and B from the lamp
access cover and lift the cover gently away
from the fixture until the lamp is clear. Avoid
straining the lamp wiring.
3. Holding the lamp by its base, pull it up and
out of the lampholder.
4. Holding the new lamp by its base only and
keeping the lamp square to the lampholder,
push the lamp contacts fully into the
lampholder.
5. Put the lamp access cover back into
position, sliding the new lamp back into the
fixture as you do so. Reinstall the
thumbscrews to secure the cover before
reapplying power.
6. After installing a new lamp, reset the lamp
hour counter (see "Lamp management" on
page 19). It may also be necessary to adjust
the lamp as described in the next section.
Lamp adjustment
WARNING! Adjust the lamp with the fixture cool. The fixture may become hot during adjustment, so
avoid contact and protect your hands with heat-resistant safety gloves.
As well as being undesirable for aesthetic reasons, a significant hot-spot in the beam will focus extra heat
onto optical components and may cause damage that is not covered by the product warranty.
After fitting a new lamp, adjustment may be required to obtain an even beam.
To adjust the lamp:
1. If the fixture has been in use, allow it to cool for at least 30 minutes.
2. Apply power, allow the fixture to reset, then
turn on the lamp and open the mechanical
shutter.
3. Aim the fixture at an even surface and make
sure no further commands can be sent by
DMX.
4. See Figure 3. Screw the 3 mm Allen screws
C, D and E in or out to obtain the most even
beam.
