Increased Efficiency

The Spectrum King LED 402 Grow Light offers the same light intensity as a high pressure sodium bulb and offers a lumen output that is comparable to HPS bulbs operating at 1000-Watts to your plant canopy. Better suited for light-hungry plants and strains the 460W LED light is perfect for plants that are particularly sensitive while only using a fraction of the energy. While it offers the same intensity as a 1000-watt HPS bulb, our 460W LED grow light uses only a fraction of electricity while emitting only about 1500 BTUs of heat. That all equates to big energy savings of over 60% in energy costs and a light that produces less heat than most of the competitors. Those energy savings equate to lower utility bills since your HVAC appliances are used less to combat the high temps common with HPS rooms. A typical return on investment is less than a year for small grows and up to18 months for commercial grow operations.

The 400+ series can be custom fit to your application with different reflectors for maximum coverage and depth. Based on your coverage area and the height of your current plants, you may select from a variety of reflectors, including:

    • 90° reflectors
    • 120° reflectors
