hydroponics FULL DUAL Spectrum HPS 400W Grow lamp grow bulb

Product Description

 all-new revolutionary HID (High Intensity Discharge) HPS (High Pressure Sodium) grow lamps are available in 2 sizes: 400w and 600w, providing 32,000 life hours with a colour temperature of 2000K. The 600w output is 155 lumens per watt, the 400w output is 140 lumens per watt. They are tailored to promote optimum development at each growth stage. The tube inflated Crystal glass offers consistent thickness allowing more even light output. Offering a mixed spectrum output with raised blue levels, the SpectraTech Technology provides an increased PAR output. HPS/HO design avoids use of barium film, which means that there is no blackening of the glass, less gas impurities in the lamp and a cleaner, more stable light output. E40 mechanical double layer base design eliminates soldering and paste, delivering a 100% inline base.

Note:The correct wattage of ballast must be used with the corresponding wattage of lamp
