The Philips GreenPower DE 1000W 400V EL Lamp is a premium double-ended high-pressure sodium (HPS) horticultural lamp designed for professional greenhouse and indoor cultivation. Engineered for use with 400 V electronic ballasts, it delivers exceptionally high photosynthetic photon output, excellent light maintenance over its service life, and a broad horticultural spectrum that supports vigorous vegetative growth, abundant flowering, and high-yield crop production. Its double-ended construction provides superior arc stability, increased efficiency, and a more uniform light distribution compared with conventional single-ended HPS lamps.

To this day, the Philips GreenPower DE 1000W 400V EL Lamp remains one of the industry's benchmark HPS fixtures, producing approximately 2,100 µmol/s PPF at around 2.1 µmol/J.

Benefits

• Delivers one of the highest photon outputs available from a 1000 W HPS lamp.
• Proven spectrum promotes strong photosynthesis, rapid flowering, and increased yields.
• Excellent lumen and PPF maintenance reduce the need for frequent lamp replacement.
• Produces a brighter, more uniform canopy than traditional single-ended HPS lamps.
• Ideal benchmark for comparing modern LED horticultural fixtures due to its long-standing use in commercial cannabis and greenhouse cultivation.

Typical Applications

• Commercial cannabis cultivation
• Greenhouse production
• Indoor flowering rooms
• High-light fruiting crops such as tomatoes, peppers, cucumbers and ornamentals
