The ETL-listed Johnson Maximizer Air-Cooled Grow Light utilizes 8 Top-Bin CREE LESs while using less energy and placing significantly less heat into the grow environment. This light will replace a 1000 watt HPS and cover a 5'x5' area for Veg and 6'x6' area for Flower, while only drawing 630 watts.

High CRI

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.

Low Heat

This fixture is duct cooled - helping with environmental control in sealed-environment agriculture. When exhausting the air outside the grow environment this fixture only adds ~1000 BTUs to the ambient air temperature. A standard 1000 watt HID can add up to 3500 BTUs per fixture.
