1 Source Four LED Profile v1.5.0 User Manual

Introduction

Congratulations on your purchase of a Source Four LED series by ETC product.

Source Four LED series’s x7 Color System™ seven-hue technology produces a light and
color quality that conventional LED systems cannot duplicate. This unique color system
produces bright, broad-spectrum whites and intense colors equally well, rendering
pigments, objects, and skin tones in a natural way.

Daylight and Tungsten fixtures use high-output white LEDs for maximum brightness and
efficacy. Tungsten interacts very well with incandescent sources, while Daylight easily
replaces a variety of HMI lamps and natural sunlight.

Quick Setups

You can use any one of the Quick Setups and fine-tune settings for either console operation
via DMX protocol or standalone operation. For advanced users, an expanded user interface
provides easy navigation to all settings and options.

Lustr+

Some of the options include:

• Multiple DMX profiles ranging from a simple 3-channel RGB profile to 8-channel direct
color and intensity control.

• Multiple dimming curve options.

• Preset colors and sequences for standalone operation.

• White point selection; white light and color behavior based on a specific color
temperature white light such as 3200K or 5600K.

• Loss-of-data behavior options.

• Power regulation modes; three output options that offer a choice between maximum
light output for lower duty cycles and maximum thermal stability and output consistency
for higher duty cycles.

Studio HD

• Balanced with x7 Color System for a spectrally rich, variable white light.

• Color temperatures from 2700K to 6500K.

• Onboard +/- green adjustment.

• Preset colors and sequences for stand-alone operation.

• Multiple dimming curve options.

• Power regulation modes; three output options that offer a choice between maximum
light output for lower duty cycles and maximum thermal stability and output consistency
for higher duty cycles.

Note About LED Fixtures

All LED sources experience some lessening of light output and some color shift over time.
Source Four LED series fixtures have complex thermal management systems to minimize
these changes. With typical usage, a fixture will still achieve at least 70% of its initial output
after 50,000 hours of use (B50, L70). In individual situations, LEDs will be used for different
durations and different levels. This can eventually lead to minor alterations in color
performance, necessitating slight adjustment to presets, cues, or programs.

All LEDs may exhibit a slight shift in output as they rise to full operating temperature. Source
Four LED series fixtures allow the selection of different power settings in order to balance
the competing requirements of thermal stability and brightness. Depending on the selected
setting, changes in output as fixtures warm up may or may not be visible to the eye.

Color Rendering Index and Color Quality Scale Ratings

Source Four LED series fixtures are evaluated for Color Rendering Index (CRI) and Color
Quality Scale (CQS) performance using measured output spectrum and optimized mix
solutions for a best spectral match to black body sources at 3200K and 5600K. Color fidelity
was also measured. These numbers may fluctuate slightly from fixture to fixture. This is a
normal characteristic of white LEDs, and this kind of variation is highly unlikely to be
apparent in most applications. The performance is the same for all fixture versions.

Source Four LED series luminaires provide excellent color rendering, particularly the color­mixing versions. A Duv rating of 0.000 indicates that the color mix used was exactly on the
black body line, with no green or magenta tint.

Daylight and Tungsten fixtures use only white-type LEDs at a fixed color temperature in
order to maximize output and efficacy.

Installation Clearances

Cooling and Duty Cycle

Desire series fixtures are fan 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 fixtures may shut down and remain off until they return to a safe
operating temperature. The fixtures provide two methods to indicate over temperature that
can be set up on the Local Settings menu. The over temperature indicators are:

Visible

The LED array glows in a dull, low intensity with only some emitters illuminated, the LCD
backlight is turned on, the LCD displays Overtemp Activated, and the Error Indicator light
turns on.

Dark

The LED array turns off and the LCD displays Overtemp Activated. The LCD backlight is
not turned on.

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.

CAUTION:

Duty Cycle

Operating the fixtures 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 series fixtures should be powered down by disconnecting from power
either at the breaker or by unplugging.
