For optimum lamp life, turn off the lamp whenever illumination is not required for
extended periods of an hour or more. However it is a good idea to keep the fixture
power on so that the fans continually operate, regardless of whether or not the lamp
is lit. This keeps air circulating internally and prevents condensation from building
up inside the fixture.
When the temperature is expected to fall below freezing, leave the fixture powered
on when not in use to keep the electronics warm. The lamp, however, may be
switched off.
Always allow the lamp to warm up fully before turning it off.
Avoid turning on several lamps at once.

Two LEDs on the rear panel display the fixture status. Normal operation is indicated
by two green LEDs. See Table 4 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.
