Fluence’s SPYDR 2i 47" is a high‑PPFD, close‑canopy LED top light built for multi‑tier cannabis cultivation with CO₂ enrichment. The 47 × 42.8 inch fixture outputs 1700 μmol/s at 2.7 μmol/J and draws about 638 W at 277 V (≈669 W at 120 V). It uses the PhysioSpec Broad R4 spectrum, supports 0–10 V dimming (10–100%), and is typically mounted 6–12 inches above the canopy. The luminaire is IP66 rated with passive cooling and an L90 lifetime over 50,000 hours. Typical flowering coverage is 4 × 4 ft (≈120 × 120 cm); retailers report average PPFD around 1,060 μmol/m²/s at 6 inches over that area. Compatible with 120–277 V and 277–480 V PSUs, the fixture offers remote or fixture‑mounted driver options and multiple hanger kits for different rack systems.
