The Focus Flex L19 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.
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.
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.
Low – In this mode the fixture reduces fan speeds throughout for a lower noise profile of the fixture.
This mode should be sufficient for most uses where lower noise is required. The fixture output is
reduced to about 80%.
Mute— Running the fixture in MUTE mode reduces the fixture to about 25% output, and all fans are
off. The fixture is totally silent.
