After being switched off, the lamp must cool for at least 8 minutes before it can be
switched back on. “Lamp On” commands sent within 8 minutes of a “Lamp Off” command
are stored and then attempted again after the time has elapsed.
The lamp can be set to start automatically as soon as power is applied to the luminaire or
started via DMX.
Discharge lamps draw an extra inrush current for a fraction of a second during startup. If a
large number of luminaires start up at the same time, this current can trip circuit breakers.
Therefore:
• If the lamp is set to start automatically when power is applied, it starts after a random
delay of 0 - 90 seconds.
• When controlling a large number of luminaires via DMX, switch on lamps one by one at
intervals of about half a second.
To obtain optimum lamp life:
• Always allow the lamp to warm up fully for 5 minutes before turning it off.
• Switch off the lamp whenever illumination is not required for extended periods of an hour
or more. Note that luminaire power should remain on at all times except during service.

To ensure free and correct effect movement even if some effects are not used for long
periods, the Exterior 1200 Image Projector runs an ‘exercise program’ and checks effect
movement every time the lamp is switched off.
In this program, all effects are moved through their whole range and the luminaire checks
the effect positioning and sensor systems.
If an error occurs during checking, the luminaire resets. If the ‘exercise program’ is
complete successfully, the luminaire waits with the cooling system active until either it
receives a command or power is shut down.
