The lamp operates under high temperature and pressure
and can explode. Always wear safety goggles to protect
your eyes and allow a hot lamp to cool for at least
5 minutes before removing it from the fixture.
Discharge lamps become more difficult to strike with age. If the lamp is difficult to strike, it
probably needs to be replaced. You can expect, on average, to get 2000 hours of use from
MSD lamps. Please refer to “Installing or changing the lamp” on page 5 for the lamp
replacement procedure.

The SynchroZap QX250 lamp assembly is adjusted at the factory. Due to differences
between lamps, however, fine adjustment may be improve performance.
1. Disconnect the fixture from AC
power.
2. (Optional) Perform a rough
adjustment: Remove the
lamp assembly and turn the
3 lamp adjustment screws
until there are 19 mm (0.75
in) between the 2 plates as
shown. Replace the lamp
assembly.
3. With controller: Turn on the
SynchroZap QX250 and
select white light with the
open gobo.
Without controller: Flip DIP-switch pins 8 and 10 on. Flip all other pins
off. Apply power to the SynchroZap QX250. After it has reset, the fixture
produces a white light with an open gobo for adjustment purposes.
