The Gavita Pro 600W 400V EL is a single‑ended high‑pressure sodium (HPS) lamp engineered for high‑voltage, high‑frequency horticultural fixtures. Designed for use with Gavita Pro electronic ballasts and reflectors, it delivers a photosynthetic photon flux around 1120 µmol/s and fits E40/E39 sockets. Retailer specifications indicate high light maintenance after 5000 hours of operation when used as intended. While coverage depends on the reflector and hanging height, a typical application with the HR96 SE reflector targets roughly an 80 × 120 cm area at about 60 cm distance in overlapping layouts for ~1000 µmol·m⁻²·s⁻¹ levels. This lamp is intended for 400 V electronic systems and should not be driven by standard magnetic ballasts. Replace on schedule to maintain optimal output.
