Growers Choice DE 600W HPS 2K Lamp: 1050 µmol/s Bloom Output
The Growers Choice DE 600W HPS runs at 2000K with 1050 µmol/s photon flux and 90,000 lumens of initial output at 150 lm/W — serious numbers for a 600W lamp that put it in the output range some 1000W single-ended fixtures struggle to match. The spectral output peaks heavily in the red and far-red range, mimicking the color temperature of autumn sunlight and stimulating the metabolic activity that drives flower development, resin production, and late-stage ripening. High-quality quartz glass maintains consistent spectral output and PAR production across the lamp's service life.
Lamp Life, UV Output, and 600W DE HPS Specifications
Rated at 15,000 hours with only 5% degradation at 10,000 hours and 90% lumen maintenance at the same mark, this lamp holds its output longer than most competitors in the 600W DE class. The UV component in the spectral output supports enhanced resin production — a detail that matters in craft cultivation where secondary metabolite expression drives product quality. Physical dimensions run 390mm × 32.5mm at just 5 oz, fitting standard 600W DE fixture platforms. Lamp operates at 110V / 6.0A on ANSI-S106/E ballasts. Not recommended for use with Nanolux dimmable ballasts. Burning position is horizontal ±15°.
Key Features
- 1050 µmol/s Photon Flux: Pushes photon output that rivals some 1000W SE fixtures, delivering serious flower-driving intensity from a 600W draw
- 2000K Deep Red Bloom Spectrum: Peaks in the red and far-red wavelengths that stimulate flowering metabolism, fruit weight accumulation, and resin production
- 90,000 Lumens at 150 lm/W: High initial lumen output with strong efficiency keeps per-photon energy costs competitive against higher-wattage alternatives
- 5% Degradation at 10,000 Hours: Maintains 95% of rated output at the 10K-hour mark, extending useful lamp life before replacement is needed
- UV Spectral Output: Includes UV wavelengths that support enhanced resin and secondary metabolite production in flowering applications
