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

The Robert Juliat Arthur is a sophisticated 800W LED followspot that exemplifies cutting-edge design and performance in theatrical and live event lighting. Engineered to provide unparalleled output, the Arthur matches the lumen output of a 2500W HMI followspot while offering a significantly more efficient LED solution. With a color temperature of 6000K, this followspot is ideal for illuminating performers in a way that enhances their presence on stage, producing a high color rendering index (CRI) of over 90, ensuring that colors are represented accurately without the need for correction filters. The Arthur is the perfect choice for both large venues and full-size theaters, delivering impressive performance even at distances of up to 40 meters, where it maintains a minimum output of 2000 lux.

Featuring an innovative optical system, the Arthur includes a fully closing iris cassette that can be easily removed for quick replacement, providing convenience and flexibility during performances. The universal adjustable gobo holder accommodates both 'A' size glass and metal gobos, allowing lighting designers to create dynamic visual effects tailored to their productions. The ergonomic dimmer control enables one-handed adjustments for dimming, panning, and tilting, facilitating seamless operation. For local control, light intensity can be adjusted via a built-in potentiometer, making it easy to fine-tune output levels on the fly.

To further enhance its versatility, the Arthur includes an optional horizontal chopper for precise masking control, which is particularly beneficial in TV studios and wide stage applications. The internal glass filter holder supports long-term use of durable colored, dichroic, or textured glass, while the individually removable color frame allows for easy gel replacements without disturbing the overall color setup. The followspot features a six-way self-cancelling boomerang color changer, providing multiple filter options for creative lighting design. A USB connector is also included for connecting additional accessories, expanding the followspot's functionality.

The Arthur's optical performance is exceptional, featuring variable zoom optics with a range of 5.5 to 15 degrees, ensuring sharp focus across all beam angles. This allows for independent control of image size and focus, crucial for precise lighting effects. The electronic dimmer operates smoothly without clipping or cut-out at low intensity levels, ensuring consistent performance throughout the dimming range. Notably, the followspot maintains its color temperature even when dimmed, providing a reliable lighting output that professionals can depend on.

Constructed in France, the Arthur is made from robust materials, including strong steel and aluminum, ensuring durability and resilience in demanding environments. The silent-running variable fans provide effective cooling, making the Arthur suitable for sound-sensitive applications such as opera houses and concert halls. The ergonomic wrap-around handle enhances comfort during operation, while captive knobs and handles ensure safety and security when working at height or during transport. Maintenance is simplified with easy access to all components, allowing for quick cleaning and re-lamping as needed. The modular design includes independent PSU, drivers, and CPU, making maintenance straightforward with a plug-and-play system.
