Fluence said it will unveil its latest horticultural innovation—the Red Sandwich—at MJBizCon 2025 in Las Vegas.
Developed over years of research into light intensity, spectrum, and distribution, the Red Sandwich, patent pending, represents an 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.
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.
