The RAY series is ideal for research facilities, vertical farms, side-canopy, and intra-canopy lighting with 6 spectral options ranging from broad white to narrow colored, and simple installation. Thier wavelengths are tailored for particular photomorphogenic responses, photoperiodic signals, chlorophyll A and B absorption, xanthophyll carotenoid pigments, and anthocyanin accumulation in plant tissue along with unknown photoreceptors to name a few. RAY22 is available in 6 spectral options in a 22 (559 mm) slim form factor for tight grow environments. Like its longer cousins, RAY22 is well-suited for research, vertical farms, side-canopy, and intracanopy use. At 44inch (1118 mm) long, our mid-length RAY44 offers 6 spectral choices and is perfect for side canopy lighting over a 4-foot area. The longest RAY family member at 66inch (1676 mm), RAY66 also offers 6 spectral options and is the versatile full-cycle top lighting for a variety of grow applications.
