Spectrum King SK402 440 Watt LED Grow Light with 120 Reflector, White

A highly reflective 440 Watt Patent Pending Full Spectrum LED Grow Light made in the USA.

The Spectrum King LED 400+ 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 440W 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 440W LED grow light uses only a fraction of electricity while emitting only about 1,350 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+ 90° reflector unit is meant for plants 2.5’-6’ tall in flower and is recommended for ceilings that are 8’-11’ tall.

Suitable Distance Over Canopy 90 Degree – Veg: 42” to 54” Flower: 18” to 24”

120° reflector: Covers 5’ x 5’ area at 12” above the canopy during flower for normal plants and should be placed up to 18” above the canopy for sensitive strains. It can cover an 8’ x 8” area in vegetative plants at 3.5’ above the canopy. The 400+ 120° reflector unit is meant for plants 18”-42” tall during flower and is your best choice for ceilings under 8’ tall.
