ARRI L7-TT Overview

ARRI continues to refine its L-Series with the Black L7-TT 7" Tungsten LED Fresnel. The key characteristic of any Fresnel is flood-to-spot capability and the L7-TT offers an impressive beam angle adjustment of 15-50°.

The L7-TT is a tunable, tungsten-balanced source, allowing you to match ambient light and existing fixtures with color temperatures from 2600 to 3600K. The on-board controller allows dimming from 100-0% and full minus green to plus green adjustment enabling matching of specific shades. All functions can be controlled via DMX, an ideal feature for broadcast studios, while RDM permits monitoring of the light's status. The L7-TT has multiple fan modes from Off for dead silent operation, to Low and Hi speeds for situations where slight fan noise is permissible. There's also a thermally activated mode.

The fixture produces the equivalent of a 1000W tungsten light while drawing only 160W 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 ten L7-TTs from a 20A, 120V outlet as opposed to two 1000W tungsten fixtures. The L7-TT has a 90 - 250 VAC on-board power supply for worldwide use. This version of the L7-TT has a manual mount with a black finish.

Variable Beam Angle: 15 to 50 Degrees
A key element of the versatility of traditional Fresnels is 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 focus adjustments of the L-Series lives up to your expectations. And, 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 Color
With the L7-TT, white light can be adjusted from 2600 - 3600K to match the ambient light, other fixtures or specific color shades.
Fan Flexibility
The L7-TT has multiple fan modes from Off for dead silent operation, to Low and Hi speed for situations where slight fan noise is permissible. There's also a thermally activated mode.
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 reaching around the fixture. Full flood-to-spot can be achieved in only three turns.
Sliding Stirrups
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.
Tilt Lock
The strong 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-TT are controllable through DMX. The L7-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.
On-board Control
The on-board controller has manual intensity adjustment and additional controls for color temperature as well as plus/minus green to adjust the hue at the touch of a button.
Energy Savings
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.
Location Applications
Lighting teams working on location will love the versatility the L7-TT achieves with its reduced form factor. Several ARRI L7-TT Fresnels can be run off a single 20A, 120V outlet, as opposed to only two 1000W tungsten Fresnels.
Upgradeable Technology
The L7-TT is an expandable platform designed to accept 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.
