Lamp adjustment
Warning! Adjust the lamp with the fixture at normal operating temperature. The fixture will be hot, so
wear heat-resistant safety gloves. Do not touch the fixture with your skin, clothing or any other
items.
Adjust the lamp immediately each time you install a new lamp, and make sure that the lamp is correctly
adjusted at all times. 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.
To adjust the lamp:
1. To optimize tolerances,
strike the lamp and run
the fixture until it
reaches normal
operating temperature.
2. Set the zoom to wide
and shutter to fully
open.
3. Aim the fixture at an
even surface and
make sure that no
further commands can
be sent by DMX.
4. See Figure 11. Turn
the three Torx 20 lamp
adjustment screws C,
D and E to minimize
any hot-spot and
obtain the most even
beam.
