The KL Panel XL IP is a high-performance fixture suited for multiple applications. For noise
critical environments such as Theater, Opera or Orchestra Halls, it offers various fan operation
modes which remove any distraction for the audience and performers. Fan Modes can be changed
remotely via the DMX control channel, allowing the fixture to offer high output or whisper
silent operation at a moment's notice. All Fan Modes smoothly transition over a brief time,
preventing unwanted attraction to the fixture.
Fan Control - Auto (Default)
Fan Control - High
Low Noise – Silent
Auto (Default)—Fans only run at the speeds needed to keep the LED engine within a safe
temperature range and ensures optimal performance of the fixture. If possible, they will turn-
off, for example, when the fixture is dimmed to a low intensity. Fans sense the ambient and
fixture temperature, and will always try to keep noise levels to a minimum. The fixture output
will only reduce when the LED engine cannot be cooled down to its safe operating range due to
high ambient temperature.
NOTE: Recommended for daily operation.
Silent—For very critical noise environments, the fixture offers two additional Low Noise
Modes for silent operation. The fixture output will be reduced, however due to the extremely
high luminous flux the fixture still offers outstanding performance. In Low Noise Modes all
parameters of the fixture operate quieter with reduced fan speeds.
Almost all fixture fans are turned off, and only run when necessary. The fixture LED power
output is reduced to 50%.
High—Fan speeds are increased throughout for the most efficient cooling of the fixture. This
mode will increase wear on the fans and should only be utilized in exceptional circumstances.
Fans will always run, even if the fixture is dimmed down. Fixture output is kept at 100% unless
the LED engine temperature reaches an unsafe temperature at which point the fixture will
reduce power carefully to ensure continued safe operation. This mode is only required in very
high ambient temperatures when automatic fan speed adjustments are not desired.
