Introduction; Features - ARRI L Series User Manual

Introduction

Thank you for selecting a LED luminaire of the L-Series from
ARRI. The L7 is a fresnel-luminaire equipped with a high
precision, micro-processor controlled LED light source. LED
luminaires are much more efficient than light sources with
conventional tungsten lamps. They are a perfect and easy
replacement for conventional fresnel-luminaires with tungsten
or daylight lamps.
The L-Series LED luminaires combine the advantages of the
LED technology with the ease of use of a traditional fresnel-
luminaire. The L7 integrates seamless into established working
practice. The optical system offers real fresnel characteristics
with an extreme smooth beam and clean shadows. The half
peak angle can be adjusted continuously from 15° - 50°.
The L7 emits white or colored light with adjustable color tem-
perature and adjustable green / magenta saturation. Please
find more detailed information in the section "Specification" on
page 45. The light spectrum is optimized for excellent color
rendition and fulfills perfect the demands of modern, digital
cameras. All models of the L7 can be controlled using the com-
mon DMX512-A protocol or the fixture menu.
The L7 can be powered by AC power. Please find more de-
tailed information in the section "Power" on page 17.

Features

Focus
Traditional fresnel-luminaires are able to spot and flood the
beam as needed. Whether it is a flood field for a pullback or a
tight spot for a bright highlight, the continuous focusability of
the L7 performs just as expected.
Versatile beam characteristics
The L7 provides the same ability as conventional fresnel-lumi-
naires to cut set elements and shape the beam with barndoors
and flags.
Even light field
Clean, defined shadows have traditionally been a trait of single
source tungsten and daylight fixtures. L7 fresnel-luminaires
provide the same single shadow properties lighting designers
expect, delivering natural results.
Vibrant colors, full spectrum lighting
True-to-life color rendition is an outstanding feature of the
L7, comparable to a full spectrum tungsten source. The fully tu-
neable white light of the L7-C can be adjusted for different skin
tones, camera sensors and mixed light environments. Full
gamut color mixing enables the rendition of all color shades,
making color filters dispensible.
Cool light beam
Like all LED light sources the L7 does emit nearly no infrared
or UV radiation and thus does not forward heat, making actors
feel comfortable in the light beam.
