GroXpress LED 340W FullSpectrum+ is Sylvania’s low‑profile horticultural toplight for compact grow spaces. The 340 W, 1–10 V dimmable fixture uses the Gro‑Lux FullSpectrum+ plant-specific spectrum and four linear LED modules with a 120° distribution to improve canopy penetration and uniformity. It is intended for 80x80 to 100x100 cm areas, suspended mounting, and passively cooled, silent operation. Typical output is about 780 µmol/s (≈2.3 µmol/J), supporting full‑cycle cultivation without natural light. Key electrical data include power factor ~0.9 and 50/60 Hz operation. The IP20 luminaire is made from anodised aluminium, weighs 8.3 kg, and is rated L70B50 50,000 hours. Approximate dimensions are 65.3 x 67.6 x 5.3 cm, suiting low ceilings and rack installations.
