RAY44 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.

Current lead time is projected to be 30 days from the time payment is received. For orders over 100 units, please contact us at 512-212-4544.

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.
