The longest member of the RAY family, RAY66 is available with six different spectral compositions for full-cycle growth and supplemental photomorphogenic response. The Fluence RAY LED grow light 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.


Current lead time projection is 2 weeks 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.
