Ushio HiLUX GRO 600W MH Double-Ended Lamp - 5500K

Ushio HiLUX GRO 600W DE MH 5500K: 1040 µmol Vegetative Output The Ushio HiLUX GRO 600W DE MH pushes 1040 µmol of photon output from a 600W draw at 5500K — a cool blue spectrum optimized for vegetative growth that shares the same spectral quality as Ushio's 1000W DE MH lamps in a lower-wattage format. Specifically designed and rated for open fixtures, these lamps are optimized to run on 600W electronic ballasts. The 600W platform lets growers maximize potential in smaller spaces or boost supplemental lighting efficiency without the heat load of a 1000W fixture. European ISO-Factory Build Quality for Professional Vegetative Rooms Made in Ushio's European ISO factory, the HiLUX GRO 600W DE carries the same build quality and batch consistency that their 1000W line is known for. Rated at 6,000 hours with an operating voltage of 220V, the lamp delivers optimized spectrum distribution, lumen output, and irradiance patterns across its service life. The 5500K color temperature sits in the daylight range that promotes strong vegetative structure — tight node spacing, thick stems, and healthy leaf development — without the excess heat that higher-wattage lamps push into the canopy. Key Features 1040 µmol Photon Output: Delivers 1000W-class spectral quality and PAR from a 600W platform with less heat and lower energy draw 5500K Cool Blue Veg Spectrum: Daylight-range color temperature drives compact vegetative structure, strong branching, and healthy leaf expansion Open Fixture Rated: Designed and rated for open reflector use — no enclosed housing requirement for this lamp 600W Electronic Ballast Optimized: Tuned specifically for 600W e-ballast operating characteristics, not just adapted from a 1000W design European ISO Factory Build: Manufactured in Ushio's ISO-certified European facility for the consistency commercial operations demand Technical Specifications Specification Value Lamp Type Metal Halide (MH) Wattage 600W Configuration Double-Ended (DE) Color Temperature 5500K Photon Output 1040 µmol Operating Voltage 220V Rated Life 6,000 Hours Fixture Rating Open Fixture Rated Growth Phase Vegetative Manufacturing European ISO Factory
