Sylvania’s Gro-Lux LED E27 Flowering is a 17 W horticultural bulb designed for photoperiodic and supplemental flowering light. It fits any standard E27 socket and operates on 120–240 V with IP44 ingress protection. The flowering spectrum mixes white, blue, deep‑red and far‑red to support bloom response, delivering a photosynthetic photon flux around 31 µmol/s and a PPFD of about 10 µmol/m²/s at 1 m. The lamp features a wide beam (about 115°) suited to broad, even coverage in small spaces and is typically specified for up to a 100×100 cm flowering area. Dimensions are approximately Ø125 × 166 mm with a weight of 0.23 kg, and service life is rated 25,000 hours (L70B50).
