If the temperature is expected to fall below freezing, leave the luminaire powered on when
not in use to keep the electronics warm. The lamp, however, may be switched off.
If the temperature inside the luminaire falls below -10° C (14° F), the zoom effect is
disabled. This may occur if the luminaire is left powered off at ambient temperature below
-10° C (14°F). However, the zoom will become active soon after power up when the lamp
is switched on and the internal temperature rises.

Two LEDs on the rear panel indicate the Exterior 1200
Wash's operational status. The LEDs are visible from a
distance.
Normal operation is indicated when LED 1 lights green. LED 2
lights green when a valid DMX signal is being received. See
Table 5: LED status messages on page 73 for other status
messages.
The LEDs flash off for a brief instant at regular intervals to prevent false readings when
the light sensor samples the light level.
