ARRI continues to expand its L-Series with the introduction of the L5-DT 5" Tungsten LED Fresnel The key characteristic of any Fresnel is flood to spot capability and the L5-TT offers an impressive beam angle adjustment of 14-50°.
The 100-0% dimmable L5-TT is a tunable light source, allowing you to match existing fixtures with color temperatures from 2,600 - 3,600K. The on-board controller allows full minus green to plus green adjustment enabling matching of specific shades and skin tones. All functions can be controlled via DMX, an ideal feature for broadcast studios, while RDM permits monitoring of the light's status.
The L5-TT LED source produces the equivalent of a 450W tungsten light while drawing only 115W for a savings of up to 75% over traditional fixtures. And low draw and heat means lower HVAC costs in the studio and a quick return on investment. You can run about fifteen L5-Cs from a 20A, 120V outlet as opposed to three or four 500W tungsten fixtures. Power options include the L5-TT's 90 - 250 VAC on-board power supply or 22-36 VDC battery options. This hanging version of the light has a black finish.
Variable Beam Angle: 14 to 50 Degree
A key element of the versatility of traditional Fresnels is the ability to spot and flood the beam as needed. Unlike traditional Fresnels, which have significant light waste in spot focus, the efficient L-Series optical system maintains the same field lumens in all focus positions.
True Fresnel Lens Light Characteristics
Whether shaping the beam to isolate talent and set elements or cutting the field to eliminate spill light, controllability is crucial to lighting. L-Series Fresnels provide the same ability to cut and shape with barndoors and flags that we have come to expect from conventional Fresnels.
Even Light Field
Clear, defined shadows traditionally have been solely a trait of single source tungsten and daylight fixtures. ARRI L-Series Fresnels provide the same single shadow properties lighting designers expect, delivering natural results.
Tunable Tungsten Output
The L5-TT's on-board controller has manual dimming adjustment. Additional controls enable color temperature tunability from 2,600 to 3,600K with full minus green to plus green hue control to match existing fixtures or ambient light conditions.
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 reaching around the fixture. 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 gives the option of pulling the fixture back and reducing its hanging height.
The strong tilt lock provides extremely secure locking, eliminating movement and slippage and ensuring that the fixtures will stay where you put them.
For broadcast studios, remote fixture control is of paramount importance, and all functions of the L5-TT are controllable through DMX. The L5-TT is also RDM compatible, providing bi-directional feedback and reporting of system status, hours on the light engine, calibration data from the internal color sensor and current DMX address with the ability to remotely assign and address all fixtures in a DMX network.
L-Series fixtures reduce electricity usage by 75% and their LED light engines last 200 times longer than normal bulbs, when compared to conventional tungsten Fresnels. These and other cost-saving attributes will combine to affect a rapid return on your investment.
Lighting teams working on location will love the versatility they can achieve in small to medium-size packages. Several ARRI L5-TT Fresnels can be run off a single 20A, 120V outlet, as opposed to only two or three 500W tungsten Fresnels.
The L5-TT is an expandable platform designed to adapt with the latest enhancements in LED chip performance. The firmware is 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.
