Horticultural applications represent an incredible market opportunity for LED suppliers and solid-state lighting (SSL) manufacturers. Whether in supplemental lighting for greenhouses or in fully contained controlled environment agriculture (CEA) operations such as indoor or vertical farms, the customizability of spectral content, flexibility of form factor, and controllability of LEDs will improve yields and enhance desirable features of all kinds of cultivars.
MegaDrive Vertical Series, California Lightworks
MegaDrive Vertical Series LED luminaires are designed to replace high-press sodium (HPS) in single-level indoor grow facilities or on shelves in multilevel configurations. Up to 27 lightweight luminaires can be chained to one power unit, reducing power equipment installation over the canopy and lessening heat output from power electronics. Programmable dual-channel spectrum control, passive cooling, and photosynthetic photon efficacy up to 3.5 µmol/J enable lighting of vegetative, flowering, and finishing stages with one fixture model. californialightworks.com

Alina luminaire and power system, RAYN Growing Systems
Alina LED luminaires feature six individually controllable color channels (white, blue, lime, green, deep red, and far red), with two optional wavebands (adding more of existing colors or including ultraviolet, far red, or other wavebands). Fixtures can be dimmed smoothly across each waveband from 0% to 100%. The power system is available in 350W, 600W, and 1500W versions to support horticultural research installations of varying sizes. Multiple modular luminaires can be ganged together and mounted within shelving systems or via suspended wires from the CEA structure. rayngrowingsystems.com

Arize Element L1000 and L2000, Current
The Arize Element Next-Generation L1000 and L2000 toplights bring 2.6-µmol/J and 3.600-µmol/J efficacy to the Element lineup, respectively. Proprietary XW Optics achieve uniform light distribution across a wide area from a slim fixture housing that reduces crop shading and enables growers to install fewer fixtures. Eight spectral options include dual-band purple and broad-spectrum white, among others. Dimming from 0V to 10V is standard. Mounting options such as unistrut, offset, and square brackets as well as universal cable offer flexible configuration. gecurrent.com

TriPlane, P.L. Light Systems
The TriPlane luminaire’s LED modules can be independently field adjusted for specific light distribution needs. A 1:1 replacement for 1000W high-intensity discharge (HID) luminaires, TriPlane lowers HVAC loads and heat stress on plants with optimal thermal management. An aluminum enclosure allows airflow around the integrated driver, and passive thermal fins on top of the LED modules dissipate heat through conduction. A standard horticultural power connector and simplified mounting brackets support plug-and-play retrofitting of existing HID lighting. pllight.com

Aelius 880, Aelius LED
The Aelius 880 luminaire is designed to address high-bay configuration in large-scale commercial grows. The 4×4-ft output area matches typical table dimensions, wasting fewer photons and thereby utilizing energy more efficiently. A copper pipe design for cooling reduces fixture weight to less than 30 lb. Four light recipes target cannabis flower and larger fruiting crops, craft cannabis, supplemental greenhouse, and various cultivars that respond to full-spectrum light. Luminaires are CE, cETLus, and DLC certified. aeliusled.com
