L7-DT

Whereas other LED fixtures have taken forms that demand sacrifices in the quality of lighting designs, the L-Series is unique in that it fits perfectly into established working practices. This means that lighting designers will not have to adapt their creative techniques, nor will studios have to change their operating procedures; conventional Fresnels can be exchanged for L7 Fresnels on a like-for-like basis, achieving substantial and immediate cost savings with minimal disruption.

L-Series Fresnels burn cold; the lack of forward heat significantly reduces studio air conditioning costs and allows for a much cooler work environment. This makes life easier on set, both for the technicians behind the lights and the talent in front of them.

True Blue-style focus knobs provide the precise adjustment and rapid flood-to-spot that users enjoy from manual, mechanical control. Knobs on both sides of the fixture ensure easy access from all positions, eliminating the need for awkward reach-arounds. Focusing is neither tedious nor time-consuming; full flood-to-spot can be achieved in only three turns.
 

The ARRI sliding stirrup design enables precise adjustment of the fixture’s center of gravity, to compensate for front-end accessories. It also creates the option of pulling the fixture back and reducing its hanging height.

With an extremely slim profile, the extruded aluminum yoke provides high strength without added weight. An optional pole-operated yoke allows full operation of pan, tilt and focus from the floor and is therefore a popular choice for many studios.
 

The high strength tilt lock provides extremely secure locking, eliminating movement and slippage and ensuring that the fixtures will stay where you put them.
 

Optional pole operation is a popular choice for many broadcast studios, enabling fast and efficient adjustment of pan, tilt and focus without the need for ladders or lifts.

For broadcast studios, remote fixture control is of paramount importance, and all functions of the L7 are controllable through DMX. The L7 is also fully RDM compatible, providing bi-directional feedback and reporting of parameters including system status; hours on the light engine; and current DMX settings (with the ability to remotely assign and address all fixtures in a DMX network).

For location applications, the ability to rapidly access all lamphead parameters directly at the light is important. For this reason, an optional on-board controller is available for the L7 Fresnels, with manual intensity adjustment and DMX settings.

With the L7-C, additional controls for color temperature and plus/minus green can be switched to manipulate hue and saturation at the touch of a button, and two fast-presets can be stored and recalled with ease.

The ARRI L-Series has launched with an LED Fresnel fixture so close to its conventional equivalent in function and performance that it creates a previously unattainable opportunity: like-for-like replacement of traditional Fresnels with LED-based units.

Quality of light begins with the field. Smooth intensity, uniform color, even illumination: all are traits shared by the L7 and conventional ARRI Fresnels. Since Fresnels are workhorses of the lighting industry, designers and technicians now have nothing new to learn in order to use LED technology.

Versatility is the key element in traditional Fresnels, especially the ability to spot and flood the beam as needed. Whether it’s a flood field for a pullback shot or a tight spot for a bright highlight, the continuous focusability of the L7 performs just as expected.

Shaping the beam to isolate talent and set elements. Cutting the field to eliminate spill light. Controllability is crucial to lighting, and the L7 provides the same ability as conventional Fresnels to cut and shape with barndoors and flags. The only part missing is the heat: the L7 features a completely cool light beam, keeping talent comfortable and air conditioning costs low.

Clear, defined shadows have traditionally been a trait only of single source tungsten and daylight fixtures. ARRI L7 Fresnels provide the same single shadow properties designers expect, delivering natural results.

Flattering, true-to-life color rendition, previously achievable only with full-spectrum tungsten sources, is a hallmark feature of the L-Series. The fully tuneable white light of the L-Series Color versions can be adjusted for different skin tones, camera sensors and mixed-light environments, while specific color shades can be matched through full gamut color mixing. Unlike other LED fixtures, this level of color control does not involve compromising the quality of the light field: the L-Series Fresnels are unique in combining uniform light and single shadow rendition with absolute control of color attributes.

Running costs is where the similarity to tungsten Fresnels ends. L-Series fixtures reduce electricity usage, which equates to dramatic cost savings in terms of power draw. Further savings are brought about by the exceptional life span of the LED light engine, which lasts around 200 times longer than a conventional tungsten lamp; the reduced maintenance and minimized power distribution will combine with other cost-saving attributes such as built-in dimming to effect a rapid return on investment.

The L-Series also facilitates energy savings outside the studio, as versatile location lighting setups can be achieved with available power, meaning no large generators and no expensive fuel bills.

We all know the pace at which LED efficiency is improving, so the L-Series is an expansible platform designed to adapt with the latest enhancements in LED chip performance. 

The light engine is fully upgradeable, ensuring that the fixtures can take advantage of technology advances as and when they happen.

The firmware is also upgradeable through the USB port on the 
rear of each unit, accommodating future control protocols such as ACN and incorporating other system enhancements that may become available in due course.
