Interlux 1000W HPS Double-Ended Grow Lamp | ~2100K Bloom Spectrum

Interlux 1000W HPS Double-Ended Lamp for Flowering Performance

The Interlux 1000W DE HPS lamp runs a red-heavy ~2100K spectrum through a double-ended arc tube that produces higher PAR and lumen output than single-ended alternatives at the same wattage. That DE architecture also reduces light deterioration over the lamp's service life — Interlux rates these for minimal spectral degradation, so the red-to-blue ratio stays consistent deeper into the burn cycle than most SE replacements hold. Compatible with high-frequency electronic ballasts and backed by a 1-year warranty.

Double-Ended HPS Architecture and Electronic Ballast Compatibility

The higher red spectral ratio targets the wavelengths that drive flower initiation, bud density, and late-stage ripening — that's what makes HPS the standard in dedicated bloom rooms even with LED adoption growing. Compared to single-ended 1000W lamps, the DE design delivers more usable photons per watt by running higher internal gas pressure across a shorter arc gap, which translates to better canopy penetration and more uniform coverage under compatible DE reflectors. It's a straightforward drop-in for any 1000W DE HPS fixture running electronic ballasts.

Key Features

• ~2100K Red-Heavy Bloom Spectrum: Concentrates output in the red wavelengths that drive flower set, fruit weight, and ripening response during mid-to-late bloom stages
• Double-Ended Arc Tube Design: Higher internal pressure produces more PAR per watt and better lumen maintenance than single-ended lamps at the same wattage
• Minimal Light Deterioration: Spectral output and intensity hold steady deeper into the lamp's service life, reducing the performance drop-off between replacements
• Electronic Ballast Compatible: Designed for high-frequency electronic ballasts — the ballast type that gets the most out of DE lamp architecture
• 1-Year Manufacturer Warranty: Backed by a warranty that covers the continuous run schedules found in commercial flowering operations
