fixtures with discharge lamps. Use the intensity control to control lamp power to fixtures with halogen
lamps. Since discharge lamps often take several minutes to re-strike and frequent re-striking wears
out the lamp faster, it is not advisable to power off the lamps just to re-strike a few minutes later.
Lamp control for built-in profile
Click to program a lamp strike command. Note: some Martin fixtures are capable of
measuring the time between when the lamp was powered off and the strike command. If this time is
less than the lamp cool down time (typically 3-6 minutes) the fixture will refuse to strike the lamp. In
this case the fixture may display a display message such as "HOT" in the display.
Click to program a lamp off command. Many fixtures require that the lamp-off command is
left 'active' for at least 5 seconds or more before actually powering off the lamp.
The lamp commands often use the same control address as shutter and strobe commands so when
programming a lamp commands sequences into a cue, make sure that no other sequence with higher
priority overwrites the commands.
Lamp off Warning
Both lamp strike and lamp off commands are programmed into the scene, so be careful not to
unintentionally include a lamp off into the current sequence.
When lamp off command is selected a warning dialog is shown - click yes to confirm the command.
Lamp off warning
Many newer fixtures that are equipped with a display have the capability of disabling lamp off
commands via DMX. This is to avoid sending a lamp off by mistake, when using a conventional DMX
console without fixture profiles. Refer to the fixture documentation for how to enable the lamp on and
off commands.

Lamp controls for user defined profiles
The lamp control is accessed by clicking the lamp icon on the fixture tool bar. The control is
only available for fixtures that support either lamp on or off commands or both. The command is stored
as part of the current scene, this means that if the sequence is saved and later used, this command
will power off the lamp. Powering off discharge lamps usually means that they will have to cool down
before being able to re-strike. Typically this will take 3 to 8 minutes.
Striking the lamps often will cause a significantly lower lamp life-time, so only power off lamps when
necessary.
