Fluence RAY44 Specs: Output, Size and Ratings This bar is 44 in long, 2.2 in wide and just 1.4 in tall. It weighs about 2 lb 3 oz, light enough to clip under a rack shelf or hang from a trellis wire. Fluence rates it at 70–85W and 110–190 µmol/s, depending on the spectrum. Efficacy spans 1.2 to 2.5 µmol/J across the range. The lower figures belong to the far-red and UV versions, which give up raw output for a narrow band. Input autosenses across 100–277V with no setting to change. Draw stays between 0.3A and 0.7A at 120V, so a long row of bars shares one circuit. A 120° optic spreads light evenly from close range. Cooling is passive, and there is no fan to clog in a humid rack. The fixture is cETL listed to UL 1598 for damp locations and carries CE marking. Fluence rates lumen maintenance at L70 beyond 150,000 hours. Running a Slim LED Grow Light Bar on Racks and Benches A slim led grow light bar earns its place where a panel fixture will not fit. On a vertical rack, the four-foot length matches a standard shelf, and one or two bars light greens or clones from a few inches away. Between greenhouse rows, growers hang the bars sideways to reach leaves the top lights miss. Research teams pick one spectrum per bench so a single variable changes at a time. Bring the bars in dimmed on the 0–10V line and raise output while you check for stretch or bleaching. Keep foliage off the lens, because contact stains the optic and scorches leaf tips. The UV version needs extra caution, since too much exposure stresses leaves rather than helping them. Choose cord length before you mount anything. Short cords keep a rack tidy, and long cords save a junction box at the end of a row. Match the plug to the circuit as well, because the twist-lock and 240V plugs will not fit a home outlet. A dimming controller is not included, so plan one for the room. Key Features 44-inch slim profile: Matches a four-foot shelf and fits between rows where a panel light cannot go. Six spectra: PhysioSpec Indoor and Greenhouse, AnthoSpec, PrSpec, PfrSpec and UVSpec in the same bar format. Autosensing 100–277V input: Works on residential and commercial circuits with the matching plug. 0–10V dimming: Connects to 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.
