The SunPulse 600W Pulse Start Metal Halide (PSMH) grow lamp is designed to work with certified high frequency (22kHz+) electronic and digital ballasts.
Sun Pulse provides a variety of Kelvin ratings so you can choose the exact light spectrum needed for each phase of your plants.
Light spectrum (Kelvin rating)
Guidelines for non-spinning 1-lamp system:
Seedlings / Cuttings - 4 K Full SpectrumVegetative - 6.4 K Day Light SpectrumLast Week of Vegetative - 4 K Full SpectrumFlowering / Fruiting - 3 K Red Orange SpectrumFinal Week - 10 K Ultra Blue Spectrum
With single lamp, single spectrum reflector, 3 K Red Orange Spectrum is recommended.
Retail and commercial applications, 4 K Full Spectrum is recommended.
Created by the GAS Technologies group of photo-biologists, plant scientists, mechanical and electrical engineers, gas chemists, and HID lamp designers, these PSMH lamps are designed with accurate solar symmetry for true photochemical reactions in living organisms, greater molecular efficiency in operations, and better color rendering.
Sun Pulse lamps are high quality materials and workmanship. Approximate life hours = 20,000 hours, with little color shift or loss of FT-CD output.
