RAY22 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 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.

  1. somthara (verified owner)

    I bought 2 ray 22″ for a 3’x3′ grow tent and it worked out fantastic! i have just recently order 3 more. the distance between nodes was impressive! ( resulted in tight bud formations ) By far the best investment I have made so far. Heat produced from the lights was very minimal, during germination the 3×3 tent was not ventilated and kept at 65% RH with 2 ray 22″ the temperature was a average 76 F. during veg the RH was kept at 45% and a filter ran, the average temp of the tent was 72 F at the top of the plants. lights were kept at 10″ above the canopy. During flowering i did have to add supplement lights cause the 2 ray 22″ was not sufficient (i was told this ahead of time from fluence support).
    I am very happy with my lights and will consider looking into spydrx for a future upgrade.
    Horticulture is my hobby and these lights are wonderful for testing . out side of 2 grows i have done with these lights i have also used them to test nutrients deficiency and over fertilizing to document the changes/characteristics in clones.
