Philips HPS AGRO Plus 1000W DE EL UNP/50 is a double-ended high-pressure sodium lamp for horticulture. It draws 1000 W and runs on high‑frequency 400 V electronic ballasts, using a K12x30s base with a parallel/horizontal operating position. The lamp delivers a warm 2000 K spectrum tailored for flowering crops and is rated around 2,100–2,120 µmol/s PPF, with PPF maintenance of 98% at 4,000 h, 96% at 8,000 h and 95% at 10,000 h. Nominal life to 10% failures is 10,000 hours. In single-fixture layouts with a suitable DE reflector, growers typically use this output over roughly a 4x4–5x5 ft flowering footprint. The UNP/50 variant denotes a 50‑lamp outer case.
