Fluence, a leading global provider of energy-efficient LED lighting solutions for commercial cannabis cultivation, is set to make a major impact at MJBizCon 2025 in Las Vegas with the unveiling of its latest breakthrough innovation—the Red Sandwich. The company will showcase this revolutionary lighting solution alongside its next-generation product lineup, including RAPTR 2, PYTHN, SPYDR 3, and VYPR 4, at Booth #15023 during the industry’s most anticipated cannabis business event.
A New Era of Controlled-Environment Lighting
Fluence has long been at the forefront of horticultural lighting research, developing LED solutions that merge advanced technology with plant science to drive higher yields and more sustainable operations. The introduction of the Red Sandwich, currently patent pending, represents a milestone in controlled-environment cannabis lighting. It embodies Fluence’s deep understanding of how light quality, intensity, and spectral distribution directly influence plant morphology, photosynthesis efficiency, and flower quality.
Developed after years of rigorous in-house testing and commercial trials, the Red Sandwich integrates dual-directional high-red lighting—simultaneously illuminating plants from above and below the canopy. This innovative design optimizes light penetration across the full canopy, ensuring that lower buds and leaves receive the same high-quality photons as the top of the plant. The result is a more balanced light environment that minimizes photobleaching and supports even flower development throughout the plant.
Fluence reports that the Red Sandwich achieves a remarkable photon efficiency of 3.4 µmol/J, a metric that places it among the highest-performing horticultural fixtures in the industry. Through this efficiency, growers can use up to 26% less energy while achieving improved flower uniformity, consistent cannabinoid production, and reduced waste from uneven crop quality.
Scientific Precision Meets Practical Application
“Red Sandwich is a perfect example of how disciplined science leads to practical innovation,” said Dr. David Hawley, Principal Scientist at Fluence. “By repositioning high-red light beneath the canopy and pairing it with complementary high-red top light, we’ve unlocked new levels of efficiency and consistency across the plant. It’s not just about producing more light—it’s about putting photons where the plant needs them most.”
Dr. Hawley, who has led numerous studies on the role of light spectra in plant development, emphasized that this design bridges the gap between academic plant science and the operational realities of commercial cultivation. The Red Sandwich empowers growers to fine-tune the light environment for maximum productivity, quality, and return on investment—especially critical as the cannabis industry faces tightening margins and increasing demand for sustainable production methods.
RAPTR 2: Dynamic Spectrum Control for the Next Generation
Alongside the Red Sandwich, Fluence will debut the RAPTR 2, a next-generation toplight fixture designed for high-intensity flowering applications. RAPTR 2 features dynamic red-plus-white spectrum control, enabling cultivators to adjust spectral balance throughout the plant life cycle. This precision control allows growers to influence morphology, resin development, and terpene expression with unprecedented accuracy.
“RAPTR 2 reflects the next stage of evolution in dynamic lighting,” Dr. Hawley added. “By giving growers precise control over spectral balance, we enable fine-tuned plant responses throughout flowering, maintain quality at higher intensities, and push efficiency further than ever.”
With up to 20% less energy consumption compared to traditional high-pressure sodium (HPS) or legacy LED systems, RAPTR 2 offers both sustainability and scalability for large indoor and hybrid facilities. The fixture’s adaptable spectrum and advanced control integration make it an ideal choice for operations adopting data-driven cultivation strategies and automated environmental management systems.
Expanding the Fluence Ecosystem: PYTHN, SPYDR 3, and VYPR 4
Fluence’s MJBizCon 2025 exhibit will also feature three additional cornerstone products that reinforce the company’s leadership in comprehensive horticultural lighting design.
- PYTHN: This purpose-built under-canopy lighting system enhances development in the lower canopy zone, an area often starved of light in dense cannabis grows. By delivering optimized photon intensity directly beneath the leaves, PYTHN encourages robust bud formation and increases the proportion of high-grade flower. When paired with Fluence’s toplights, PYTHN creates a fully immersive lighting environment that promotes balanced plant growth from root to tip.
- SPYDR 3: Marking the tenth anniversary of its debut at MJBizCon, SPYDR 3 continues the legacy of the original SPYDR system that revolutionized multi-tier cultivation. The latest generation incorporates higher photon efficacy, refined spectral tuning, and advanced heat management—making it ideal for vertical farming and dense canopy environments. Its evolution underscores Fluence’s commitment to continuous improvement and customer-driven innovation.
- VYPR 4: The next generation of Fluence’s greenhouse toplighting solution, VYPR 4 is engineered for high-output operations that demand reliability and uniform light distribution across expansive grow areas. It integrates seamlessly into both natural-light and fully controlled-environment systems, delivering consistent performance that supports year-round productivity.
Together, these products reflect Fluence’s comprehensive approach to lighting design—one that considers every layer of the plant canopy, every phase of growth, and every operational variable that influences yield and quality.
Driving the Future of Cannabis Cultivation
The debut of the Red Sandwich and Fluence’s expanded product portfolio arrives at a pivotal moment for the global cannabis industry. As cultivators face rising energy costs, evolving regulatory frameworks, and increasing competition, technological innovation has become central to maintaining profitability and product quality.
Fluence’s solutions are engineered not only to boost crop performance but also to reduce operational costs and environmental impact. The company’s continued focus on photon efficiency, spectrum optimization, and scientific validation positions it as a trusted partner for cultivators seeking long-term sustainability and success.
At MJBizCon 2025, Fluence will host live demonstrations and scientific discussions at Booth #15023, where attendees can interact with the company’s research and product teams. These sessions will explore how controlled light spectra influence secondary metabolite production, plant architecture, and overall cultivation efficiency. Visitors will also gain insight into upcoming research initiatives and collaborative opportunities within the global Fluence network.
