OSRAM 1000W HPS Grow Lamp | High Output Flowering Bulb AU

Commercial-grade 1000W HPS output built for maximum yield and long-term reliability.

The OSRAM CWHPS 1000W is engineered for serious growers running large-format indoor and commercial operations. Built on over 100 years of OSRAM lighting innovation, it delivers high-intensity flowering output with industry-leading photon maintenance and a ceramic arc tube construction designed for demanding grow environments.

Why Growers Choose OSRAM at 1000W

>90% Photon Flux Retention at 12,000 Hours

Most HPS lamps degrade significantly after the first few thousand hours. The OSRAM CWHPS maintains over 90% of its photon output at 12,000 hours — delivering consistent PPFD and flowering performance across a significantly longer operational lifespan than standard HPS lamps.

Ceramic Arc Tube Construction

The ceramic arc tube design provides superior heat resistance and spectral stability compared to quartz arc tubes. It maintains consistent colour temperature and output across the lamp’s lifespan, reducing the spectral drift that affects flowering performance in lower-grade HPS lamps.

Advanced Ignition System

Reliable cold and warm restrike ignition with stable arc operation from startup. Consistent ignition reduces ballast stress and extends both lamp and ballast lifespan in high-cycle commercial environments.

Flowering-Optimised Spectrum

High-intensity red/orange output (550–700nm) drives chlorophyll absorption, bud development, and deep canopy penetration at 1000W — covering large grow areas with the photon density required for commercial-scale flowering performance.

Low Installation Cost

Compatible with standard 1000W HPS ballasts — magnetic and digital. A direct drop-in upgrade for any existing 1000W HPS fixture with no additional infrastructure cost.

Is 1000W HPS still viable for commercial growing?

Yes — particularly for large grow rooms where point-source intensity and deep canopy penetration at height are priorities. At 1000W, the OSRAM CWHPS delivers photon density that covers larger footprints than 600W systems, with the photon maintenance spec to sustain that output across commercial production cycles.

What ballast does the OSRAM 1000W HPS require?

A compatible 1000W HPS ballast — magnetic or digital. Always match ballast wattage to lamp wattage. Digital ballasts are recommended for improved efficiency and dimming capability.

Best 1000W HPS bulb Australia — what separates commercial-grade lamps

Photon maintenance over lamp life, arc tube construction quality, and ignition reliability under high-cycle commercial conditions. The OSRAM CWHPS leads on all three — built to commercial horticultural standards with a proven track record in large-scale operations.
