The ION 120W Under Canopy LED is a purpose-built horticultural lighting solution engineered to energize the lower canopy where traditional top lights fall short. Delivering 360 µmol/s of output at 3.0 µmol/J efficiency, it penetrates dense foliage to activate hidden bud sites, boost photosynthesis, and significantly increase overall flower quality and yield.

Designed with a cannabis-optimized spectrum, it features balanced blue, enhanced red, deep far-red, and penetrating green wavelengths to drive structural growth, improve light distribution, and ignite the Emerson Effect—accelerating flowering and resin production in parts of the plant that typically lag behind.

With its commercial-grade build (IP65 rating, 0–10V dimming, passive cooling) and proven ROI in a single harvest cycle, the ION 120W UCL turns your plant’s lower third into a productive, top-shelf canopy zone.

Key Benefits:

  • Stimulates bud sites normally lost to shade

  • Enhances cannabinoid and terpene production

  • Promotes uniform ripening and flower density

  • Reduces labor by minimizing larf and trimming needs

  • Maximizes sellable yield per square foot

  • Energy-efficient with professional-grade durability

Bottom line: The ION 120W Under Canopy LED is the final piece in a high-performance cultivation setup—unlocking untapped yield potential, increasing flower quality, and delivering rapid return on investment.

Spectrum Matters

The carefully optimized under canopy spectrum in the Ion 120W LED targets light absorption gaps within key photoreceptors and pigments beyond traditional top-light wavelengths. Purpose-built for controlled cultivation environments, it enhances physiological activity during critical reproductive stages, significantly improving lower canopy performance. The intensified output of red and far-red wavelengths, precisely blended within the full light spectrum, accelerates bud development and resin formation. The overall photon distribution is engineered for deep penetration, ensuring uniform light exposure. Additionally, the Ion’s balanced spectral temperature promotes ideal visual clarity for plant inspection, enabling accurate monitoring and optimized plant care.
