The Gavita 400W Enhanced HPS is a single‑ended 230 V high‑pressure sodium lamp with an E40 base, designed for use on high‑frequency electronic ballasts such as Gavita DigiStar. The enhanced spectrum supports both vegetative growth and flowering. Output is rated at 725 µmol/s PPF with approximately 56,500 lumens, and light maintenance remains above 95% after 5,000 hours of operation. Retailers recommend a 1×1 m (3×3 ft) flowering footprint when paired with an appropriate reflector and mounting height. This lamp is intended as a replacement bulb for compatible HPS fixtures and can also run on conventional magnetic ballasts. It is a straightforward option for growers who need a reliable, brand‑matched 400 W HPS source with stable output and consistent spectrum.
