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.
Raising the light higher above your plants increases the light coverage, but also decreases the light intensity. Therefore, it is important that you find the appropriate balance between intensity and coverage. Each Spectrum King LED grow light has a been rated to cover a determined area.
90° reflector: Covers 4’ x 4’ area at 18” above the canopy for normal plants and should be placed up to 24” above the canopy during flower for sensitive plants. It can cover up to an 8’ x 8’ area for vegetative plants at 4’ above the canopy. 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.

Q: Why is Spectrum King not big on PAR and PPF?
A: Many people ask us for PPF charts and umols /w and why we don’t publish that data. The reason is because the formulas that are used to calculate PAR use a limited spectral range from 400-700nm, as a company that sales a full spectrum light that produces wavelengths outside those ranges we would only be cheating ourselves by not being able to publish what our light is truly capable of, true sunlight quality.
