Agrosun Double-Ended High Pressure Sodium (HPS) Lamp, 1000W

Agrosun Double-Ended 1000W HPS Lamp — High-PAR Output for Electronic Ballasts

High pressure sodium (HPS) lighting remains a proven technology for high-intensity indoor cultivation. Double-ended (DE) lamps operate differently from single-ended designs: the electrodes are positioned at both ends of the arc tube rather than one, which produces a more stable arc, higher PAR output, and longer maintained lumen output over the lamp's lifespan. DE lamps require electronic high-frequency ballasts and cannot be used with older magnetic ballast systems.

The Agrosun Double-Ended 1000W HPS lamp delivers 2,100 µmol/s of PAR output, optimized specifically for high-frequency electronic ballast operation. The lamp's spectrum is formulated with high proportions of both red and blue light: red light supports strong plant development during flowering, while blue light promotes robust, compact plant structure. Manufactured in the EU, it is specifically designed for high frequency electronic ballasts. Replacement every 9-12 months of operation is recommended to maximize yields and manage energy consumption as lumen output declines with use.

Key Features & Benefits

• 2,100 µmol/s PAR output — high photosynthetically active radiation output at 1000W input — optimized for high-intensity cultivation requirements.
• High red light proportion — elevated red spectrum output promotes strong plant development during flowering phases.
• Blue light for plant structure — blue light component supports robust, compact plant structure during vegetative and early flower stages.
• Optimized for electronic ballasts — specifically designed for high-frequency electronic ballasts — not compatible with magnetic ballast systems.
• EU manufactured — manufactured in the European Union to EU quality and specification standards.
• 9-12 month replacement interval — replacing every 9-12 months of operation maintains PAR output, maximizes yields, and manages energy consumption efficiency.

Who Should Use the Agrosun Double-Ended 1000W HPS Lamp

Indoor growers running high-frequency electronic ballasts in 1000W HPS lighting systems who need a replacement lamp or are speccing out a new high-intensity lighting setup for a grow room or greenhouse with demanding light requirements.

HPS Lamp Replacement Schedule

HPS lamps maintain their rated wattage throughout their operational life, but PAR output — the light that drives photosynthesis — declines progressively from the first use. A lamp delivering full wattage after 18 months may be outputting significantly less PAR than a new lamp at the same electrical draw. Replacing the Agrosun DE lamp every 9-12 months of operation keeps PAR output in the productive range, avoids a progressive decline in yield that can be difficult to diagnose, and ensures the energy cost per unit of PAR stays within an efficient range.

Frequently Asked Questions

What ballast type does the Agrosun DE HPS lamp require?

The Agrosun Double-Ended 1000W HPS lamp is specifically designed for high-frequency electronic ballasts. It is not compatible with older magnetic ballast systems. Consult your ballast documentation to verify compatibility before purchasing.

What is the PAR output of this lamp?

The Agrosun Double-Ended 1000W HPS lamp delivers 2,100 µmol/s of PAR (photosynthetically active radiation) output — the light spectrum that drives photosynthesis in plants.

Why use a double-ended HPS lamp over single-ended?

Double-ended HPS lamps position electrodes at both ends of the arc tube, producing a more stable arc, higher initial PAR output, and better maintained lumen output over the lamp's lifespan compared to single-ended designs at the same wattage.

How often should I replace the lamp?

Agrosun recommends replacing the lamp every 9-12 months of operation. Even though the lamp continues to draw full wattage, PAR output declines with use. Regular replacement maximizes yields and keeps energy-per-PAR efficiency in the productive range.

What spectrum does this lamp provide?

The Agrosun DE HPS lamp provides high proportions of both red and blue light. Red light supports strong plant development during the flowering phase; blue light promotes robust, compact plant structure during vegetative growth.
