The Johnson CX-9 LED grow light utilizes 9 Top-Bin CREE LES Chips while using less energy and placing significantly less heat into the grow environment. This light will replace a 1000 watt HPS while only drawing 540 watts. At 2.58 umol/j, the CX-9 is extremely efficient. No other grow light comes close.
Growers can expect up to 1.5 grams/watt with this fixture depending on genetics and environment.
Boasting a 80+ CRI (color rendering index) and 3500K spectrum, Johnson Grow Lights provide sun-like light nutrition for robust, healthy growth and flowering. The 80+ CRI ensures that the light provided will be used efficiently by the plants. Flower quality and resins are also increased from the added blue wavelengths and decrease in radiant heat into the canopy.
Typical HPS lamps only have a CRI of <40. This means that the areas in the center of the light pattern surpass the light saturation point of the provided wavelengths and lack the other wavelengths that are essential to optimum plant growth and health.
Even light spread
HID fixtures typically use a single lamp and reflector. Johnson Grow Light contain multiple light sources which promote better penetration and a more even light spread. An even light spread contributes to the plants ability to absorb the provided light.
A typical 1000 watt HPS fixture introduces 3500-4000 BTU's of heat into the growing environment. Johnson Grow Light fixtures introduce only 800 BTUs when air-cooled and 1600-2000 BTU's when standing-alone in the grow environment.
