Robert Juliat Arthur - 800W 6000K LED Followspot with 5.5 to 15-Degree Zoom and Top Controls/DMX in Black Finish

The Robert Juliat Arthur is a high-performance 800W LED followspot that exemplifies the latest advancements in lighting technology. Designed for long-throw applications, this followspot delivers outstanding brightness and color quality, matching the lumen output of traditional HMI 2500W fixtures while offering a more efficient and quieter operation. With its cool white 6000K LED source, the Arthur ensures exceptional visibility and performance in various venues, from theaters to concert halls and opera houses.

One of the key features of the Arthur is its impressive output capability, achieving a minimum of 2000 lux at a distance of 40 meters (200 fc at 130 ft), making it an ideal choice for productions requiring powerful illumination. The followspot's design includes a variable zoom range of 5.5 to 15 degrees, allowing for precise control over the beam angle. This flexibility makes it suitable for both focused lighting on performers and wider coverage for scenic elements. The smooth electronic dimming feature, which retains the quality of light during transitions, further enhances its usability in live productions.

The Arthur is equipped with a fully closing iris that is controlled from the top of the unit, enabling quick adjustments to the beam size while maintaining ease of access. The ergonomic design includes a dimmer control lever located on top, allowing for one-handed operation of both dimming and iris functions. This PTC (Push To Close) model simplifies user interaction, making it particularly effective in fast-paced environments. An integrated graduated scale on the side of the unit provides a reliable reference for focus adjustments, ensuring quick and efficient setup.

In addition to its optical prowess, the Arthur includes a comprehensive range of features aimed at enhancing its versatility. The internal glass filter holder accommodates durable colored, dichroic, or textured glass for long-term use, while the removable color frame allows for easy gel replacements without removing the entire color cassette. The followspot also comes with a 6-way self-cancelling boomerang color changer, providing multiple filter options for creative lighting effects. Additionally, a USB connector is available for connecting additional accessories, expanding the followspot's functionality.

The followspot's construction emphasizes durability and ease of maintenance. Built in France from strong steel sheet and aluminum, the Arthur is designed to withstand the rigors of professional use. The electronic flicker-free power supply ensures easy, plug-and-play installation, and the cooling system incorporates silent-running fans to maintain optimal operating temperatures without excessive noise. The electronic thermal management system protects the unit from overheating, making it suitable for extended use in demanding environments.

The Arthur features a comprehensive DMX control interface, compatible with various data protocols, including DMX, RDM, Art-Net, and sACN. This allows for seamless integration into existing lighting systems, providing users with the ability to control parameters such as dimming curves and response times remotely. Furthermore, the inclusion of an Ethernet-DMX node and RJ45 connectors facilitates daisy chaining and effective communication between multiple fixtures, enhancing the overall lighting design flexibility.

With its combination of powerful output, advanced features, and robust design, the Robert Juliat Arthur is a leading choice for lighting professionals seeking a reliable, high-quality followspot that excels in a variety of performance settings.
