The professional lighting industry has witnessed a significant technological leap with the official introduction of the Xoop Digital FRSNL M by HOF, a fixture designed to redefine the capabilities of traditional Fresnel spotlights through integrated digital optical control. Unveiled at the LEAT con 2026 in Hamburg, the Xoop Digital FRSNL M represents a departure from mechanical beam-shaping methods, instead utilizing the proprietary Frostyx Smartglass technology to provide lighting designers with unprecedented control over light distribution. This innovation allows for the independent digital adjustment of horizontal and vertical beam spreads, eliminating the need for physical lens swaps or manual barn door adjustments in many scenarios. By integrating high-output LED technology with advanced digital optics, HOF aims to address the evolving demands of theater, film, and high-end corporate event production.
The Evolution of Digital Optics: Frostyx Smartglass Technology
At the heart of the Xoop Digital FRSNL M is the Frostyx Smartglass technology, a revolutionary advancement in the field of optoelectronics. Historically, Fresnel lanterns have relied on the physical movement of the light source relative to a stepped lens to adjust the beam angle, supplemented by external barn doors to shape the light. The Frostyx system replaces or enhances these traditional methods by using an electronically controlled glass substrate that can change its diffusion characteristics in real-time.
This technology allows the user to manipulate the horizontal and vertical dimensions of the light cone independently. For instance, a lighting technician can transform a standard circular wash into a wide horizontal strip for a stage wash or a narrow vertical beam for architectural highlighting, all without leaving the control console. This functionality is accessible via DMX and RDM protocols, as well as through physical rotary encoders located on the rear of the unit. The ability to shape light digitally not only speeds up the focusing process during load-ins but also allows for dynamic beam-shaping effects during a live performance—a feat previously impossible with static Fresnel fixtures.
Advanced Color Science: The 200W RGBMA Engine
To complement its advanced optics, HOF has equipped the Xoop Digital FRSNL M with a high-performance 200-watt 5-in-1 LED engine. Utilizing a color palette consisting of Red, Green, Blue, Mint, and Amber (RGBMA), the fixture achieves a level of color fidelity that surpasses traditional RGB or RGBW systems. The inclusion of Mint and Amber LEDs is particularly critical for professional environments; Mint fills the spectral gaps often found in LED sources to improve the rendering of skin tones, while Amber ensures rich, warm whites and deep saturated oranges and yellows.
The technical specifications of the light engine are tailored for the most demanding visual environments. The fixture supports a correlated color temperature (CCT) range from a warm 1,800 Kelvin to a cool 20,000 Kelvin, covering the full spectrum from candlelight to deep daylight and beyond. Furthermore, the unit comes pre-programmed with 255 LEE filter presets, allowing designers to quickly match the output to industry-standard gel colors. For smooth transitions, the Xoop Digital FRSNL M features 16-bit dimming resolution, which ensures flicker-free fades even at the lowest intensity levels, supported by various selectable dimming curves to emulate the behavior of halogen lamps.
Optimization for Film and Broadcast Applications
Recognizing the increasing convergence of live events and digital broadcasting, HOF has optimized the Xoop Digital FRSNL M for camera compatibility. One of the primary challenges in using LED lighting for film and television is the "flicker" effect caused by Pulse Width Modulation (PWM) frequencies that conflict with camera shutter speeds. The Xoop Digital FRSNL M addresses this with an adjustable PWM frequency ranging from 600 Hz to 20,000 Hz. This high-frequency capability ensures that the light remains stable even when captured by high-speed cameras used in slow-motion cinematography or ultra-high-definition 8K broadcasts.
The color rendering metrics of the RGBMA engine also play a vital role in broadcast settings. By providing a full-spectrum output, the fixture maintains a high Color Rendering Index (CRI) and Television Lighting Consistency Index (TLCI), ensuring that colors appear natural on screen and reducing the need for extensive post-production color correction.
Hardware Design and User Interface
The physical construction of the Xoop Digital FRSNL M reflects HOF’s commitment to the rigors of the rental and touring markets. The unit features a robust housing designed for thermal efficiency, ensuring that the 200W LED engine remains within optimal temperature ranges during extended use. On the rear panel, the fixture is equipped with two "push-and-turn" rotary encoders that provide intuitive local control over intensity, color, and beam shape.
A standout feature of the hardware interface is the full-digital color display. In a move toward improved ergonomics, the display is equipped with a gravity sensor that automatically rotates the interface based on the orientation of the fixture. Whether the light is mounted on a floor stand or hung upside down from a truss, the menus remain legible to the technician. For integration into complex control networks, the fixture supports standard 5-pin DMX in/out and RDM (Remote Device Management), allowing for remote configuration of addresses, fan modes, and personality settings from the lighting desk.
Chronology of Development and Market Introduction
The journey of the Xoop Digital FRSNL M began several years ago as HOF sought to modernize the traditional Fresnel fixture, which had remained largely unchanged in form factor for decades. Following the successful launch of earlier LED-based models in the Xoop line, R&D focused on the "missing link" of digital lighting: the elimination of mechanical beam shaping.
- Phase 1: Research into Smartglass (2023-2024): HOF engineers collaborated with material scientists to adapt polymer-dispersed liquid crystal technology for high-intensity lighting applications, ensuring the glass could withstand the heat and UV output of a 200W LED.
- Phase 2: Prototype Testing (2025): Beta units were placed in select European theaters and film studios to gather feedback on the RGBMA color mixing and the responsiveness of the digital beam shaping.
- Phase 3: Final Refinement (Early 2026): Adjustments were made to the software to include the auto-rotating display and the expansion of the LEE filter library.
- Phase 4: Official Launch (October 2026): The Xoop Digital FRSNL M makes its public debut at LEAT con in Hamburg, positioned as the flagship Fresnel in HOF’s digital lighting portfolio.
Strategic Presence at LEAT Con 2026
The choice of LEAT con 2026 for the product’s debut is a strategic move by HOF. Held in Hamburg from October 6th to 8th, LEAT con (Live Entertainment and Technology Convention) has emerged as a premier hub for the European event technology industry. Located in Hall A1, Stand K11, HOF’s exhibit allows industry professionals to experience the Frostyx technology firsthand.
The convention provides a platform for HOF to engage with its primary demographic: technical directors, lighting designers, and rental house owners. By demonstrating the Xoop Digital FRSNL M in a live environment, HOF highlights the fixture’s versatility across multiple sectors, including theater, corporate branding, and live entertainment.
Industry Implications and Market Impact
The introduction of digital beam shaping via the Xoop Digital FRSNL M is expected to have a ripple effect across the production industry. For rental companies, the fixture offers a "Swiss Army Knife" solution. Because the beam can be reshaped digitally, a single unit can fulfill the roles of multiple specialized fixtures, potentially reducing the inventory volume required for a production and lowering transportation costs.
In the theater world, the reduction in manual labor is a significant factor. Traditionally, adjusting the "wash" on a stage required a technician to climb a ladder or operate a lift to manually adjust barn doors on every fixture. With the Xoop Digital FRSNL M, these adjustments can be made from the ground via the lighting console, significantly increasing safety and reducing the time required for technical rehearsals.
Furthermore, the environmental impact of the shift to high-efficiency LED technology cannot be overlooked. The 200W LED engine provides an output comparable to traditional 1,000W or 1,200W tungsten fixtures, representing a massive reduction in power consumption and heat generation. This leads to lower air conditioning costs in studios and theaters, contributing to more sustainable production practices.
