Fluence RAY22 Specs: Output, Build and Ratings
The RAY22 is a slim bar light, only 22 in long, 2.2 in wide and 1.4 in tall. It weighs about 1 lb 4 oz, so rack shelves and trellis wires carry it without extra hardware. It is rated at 35–50W and 60–95 µmol/s, depending on which spectrum you choose. Efficacy runs from 1.2 to 2.4 µmol/J. The low end comes from the specialty far-red and UV channels, which trade raw output for a narrow band. Input is autosensing across 100–277V, and the draw stays under about 0.4A even on 120V. That lets a long string of bars share one circuit. The optic spreads light over a 120° beam, wide enough to wash a shelf from close range. Cooling is passive, with no fan to clog in a humid rack. The bar is cETL listed to UL 1598 for damp locations and carries CE marking. Lumen maintenance is rated at L70 beyond 150,000 hours.
Where a Multipurpose LED Light Bar Earns Its Place
A multipurpose led light bar like this one makes sense where a big fixture cannot fit. On a vertical rack, one or two bars per shelf light microgreens, lettuce or clones from a few inches away. In a greenhouse, growers run the bars between rows of high-wire crops to reach leaves the top lights miss. Research teams use the six spectra to test one variable at a time on the same bench. Start with the bars dimmed on the 0–10V line, then raise output while you watch for stretch or bleaching. Keep the bars close but not touching foliage, because leaf contact stains the lens and scorches tips. Pick the cord length before you hang anything. The short cord keeps a tidy rack, while the long cord saves a junction box at the end of a row. Match the plug to the circuit too, since the twist-lock and 240V plugs will not fit a home outlet. The dimmer controller is not included, so plan one for the room. Fluence backs the bar for three years as standard, with an extended five-year option.
Key Features
- Slim 22-inch profile: Fits between rack shelves and crop rows where a panel light cannot go.
- Six spectra: PhysioSpec Indoor and Greenhouse, AnthoSpec, PrSpec, PfrSpec and UVSpec on one bar format.
- Autosensing 100–277V input: One bar works on residential and commercial circuits with the right plug.
- 0–10V dimming: Ties into a room controller for ramps and research dosing; controller sold separately.
- Passive, damp-rated build: No fans, and a UL 1598 damp-location listing for humid racks and greenhouses.
- Two cord lengths, four terminations: 6 ft or 15 ft cords with pigtails, NEMA 5-15P, 6-15P or L7-15P.
