The JN-300W DELUXE LED grow light is the most revolutionary plant lighting product since the inception of High Pressure Sodium lamp. Consuming only 100 watts of power and producing virtually no heat, it boasts light intensity and growth rates exceeding that of a 1000W HPS. Tests have shown that the LED grow light gives your plants greater light intensity and growth rates than a standard 1000W HPS grow light, yet uses only 1/6th of the electricity!The concept of the JN-300W DELUXE LED grow lighting is simple it uses highly efficient 1-1.2 watt LEDs, uses only the exact spectrums required for photosynthesis, and uses wide angle directional bulbs. The 1 -1.2watt LED is one of the most efficient light sources in the world (lumens per watt). By using only the spectrum required, no light is wasted in the spectrums of light that do little or nothing for a plants growth such as green light. Lastly the directional LEDs ensure 100% of the light is pointed downwards they do not rely upon reflective materials to direct the light. The directional nature of the LEDs ensures 100% of the light is pointed downwards so no reflective material is needed. The low heat emission also eliminates the need for ducting and heat exhaust fans. Our company warrants its JN-300W DELUXE grow light to be free from defects on materials and workmanship.
