Fluence VYPR 4x2 is a dual‑bar, full‑cycle top‑lighting fixture for greenhouses and single‑tier rooms. The 4x2 combines two VYPR 4 light bars on one 800 W power supply and operates on 200–480 V input. Nominal draw is around 840 W, depending on mains voltage and spectrum. It is offered with PhysioSpec BROAD R4 or R8 spectra and can be paired with clear‑glass or wide‑beam optics to optimize uniformity at practical truss heights. The fixture is wet‑location rated and carries cETLus, CE, UKCA, and DLC certifications. L90 lifetime is rated at 50,000 hours. Per series specifications, each bar outputs about 1,120 μmol/s (R4) or 1,320–1,370 μmol/s (R8). Dimensions per bar are 60 × 10.7 × 9.1 cm; a duo mount uses two bars for higher output and efficient HPS retrofits.
