Description
The ARRI L-Series is an LED Fresnel fixture so close to its conventional counterpart in function and performance that it creates a previously unattainable opportunity: like-for-like replacement of traditional Fresnels with LED-based units.
Light Engine 2
Compared with previous L7-C models, the LE2 range are now 25% brighter.
The L7-C is the first LED fixture to truly incorporate the Fresnel characteristics of continuous focusability from spot to flood and a smooth, homogenous light field. The L-Series takes full advantage of LED technology and allows for complete control over the color and intensity of light. Light emitted from the L7 is specifically calibrated for optimal reproduction on broadcast and digital cinema cameras, ensuring pleasing skin tones and vividly rendered colors. Constructed to be robust and ergonomic, the L7-C meets the quality and design standard for which ARRI is known.
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.
Energy Savings
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.

Allows for only active cooling (with a fan). This unit is smaller and lighter than the Hybrid version but cannot run passively (without the fan)
Cool Burning and Cost Saving
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.
Focus Knobs
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.
Sliding Stirrup
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.
Yoke
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.
Tilt Lock
The high strength tilt lock provides extremely secure locking, eliminating movement and slippage and ensuring that the fixtures will stay where you put them
DMX Control
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).
On-Board Control
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.
