By Itself Or In Partnership
Perfect as a sole-source lighting solution, or as supplement to SPYDR/VYPR.


Utility player.

The Fluence RAY LED grow light bar is available in three sizes: 22″, 44″ and 66″, and it is available with six different spectral compositions for full-cycle growth and supplemental photomorphogenic response. The Fluence RAY comes with a 120-degree beam angle for close-proximity cultivation, which minimizes the amount of light on the floor, thus maximizes your growth rate and your ROI.

The LED grow light bars are UL-rated for damp locations and are 0-10V dimmable, so you can achieve the amount of PAR your plants need at each stage of their lifecycle. Each fixture comes with the power supply and everything you need to immediately use the lighting system over your crop.

All RAY models are dimmable with our light intensity Dimmer for precise control over PPFD, and offer the flexibility to instantly accommodate a new crop with varying light requirements.


At 44″ long, our mid-length RAY44 offers six spectral choices and is perfect for side canopy lighting over a 4-foot area.

Current lead time projection is 45-60 days from payment received. We are experiencing high volume and ramping our manufacturing as quickly as possible without sacrificing quality.

Suitable for operation in still air ambient temperatures from -40°C (-40°F) to 35°C (95°F) when suspended and up to 30°C (86°F) when surface mounted. Operating temperature ranges between 25°C (77°F) to 30°C (86°F) above ambient.

We recommend at least one ft3/S of airflow to ensure efficient cooling. Proper air flow will also increase the maximum suitable operating temperature and help extend lifetime of system.
