Cooling and Duty Cycle
The D40/D60 XTI fixture is convection cooled and can operate all channels at full power
continuously in ambient temperatures up to 40°C (104°F).
If ambient conditions exceed 40°C (104°F) or fail to allow sufficient airflow, over a long
period of time, the fixture may shut down and remain off until they return to a safe operating
temperature. The fixture provides two methods to indicate over temperature:
• Visible: The LED array glows in a dull, low intensity with only some emitters
illuminated and the Error Indicator light turns on.
• Dark: The LED array turns off.
LED life is adversely affected by high-temperature operation. When operating under
elevated ambient temperatures, avoid turning all channels to 100% for extended periods,
such as channel checks or focusing.
C A U T I O N : Duty Cycle
Operating the fixture in higher ambient temperatures or low-airflow situations may
cause the power supply to shut down. Following a cool-down period, the power
supply will automatically reset and the fixture will return to operation.
It is good practice to power down any device with on-board electronics to limit
unnecessary wear on the devices and eliminate residual use of electricity. When
not in use, Desire fixtures should be powered down by disconnecting from power
at the breaker.
