Fluence, a leading global provider of energy-efficient LED lighting solutions for commercial cannabis production, will unveil its latest horticultural innovation—the Red Sandwich—at MJBizCon 2025 in Las Vegas. Attendees can see it alongside Fluence’s newest fixtures, including RAPTR 2, PYTHN, SPYDR 3, and VYPR 4, at Booth #15023.

Developed over years of research into light intensity, spectrum, and distribution, the Red Sandwich, patent pending, represents a major advancement in controlled-environment cannabis lighting. By strategically balancing high-red spectra and intensity delivered simultaneously through top and under-canopy lighting, Fluence achieved photon efficiency of 3.4 µmol/J which resulted in up to 26% less energy used, while improving flower uniformity and helping eliminate photobleaching.

“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.”

Fluence will also showcase RAPTR 2, its next-generation toplight featuring dynamic red-plus-white spectrum control that uses up to 20% less energy.

“RAPTR 2 reflects the next stage of evolution in dynamic lighting,” added Hawley. “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.”

Additional products on display include PYTHN, Fluence’s purpose-built under-canopy lighting designed to strengthen lower-canopy development and boost A-grade bud production; VYPR 4, the next-generation greenhouse toplight for high-output operations; and SPYDR 3, the latest generation of the breakthrough multi-tier lighting solution introduced at MJBizCon 10 years ago.

Together, these solutions demonstrate how precision control and science-backed design are reshaping efficiency, quality and yield for commercial cannabis operations.
