Product Information

Spectrum King LED (440 Watt Usage)


Spectrum King LED Grow Lights are designed to mimic natural outdoor sunlight.

Spectrum King LED Grow Lights produce spectrums from 380-800nm.

This means that not only virtually every visible colour is present in the light, but also ones you can't see.

The Spectrum King 400 series lighting fixtures truly mimic sunlight more so than traditional HPS lamps, while matching intensities of over 100,000 Lux.

  • The 400 series (90º) has the greatest coverage area, exceeding that of a 1000watt HPS light

Lighting is as important for plants as it is for humans. When you can’t provide real sunlight, our LED grow lights provide an excellent alternative, but the wrong LEDs can do more harm than good. Just think of the effect long dark winter days have on you and how much better it is in summer. It’s the same for plants and the right quality and intensity of light does make all the difference.

That’s where Spectrum King LED comes into the picture. We have the best LED grow lights that are designed to provide you richer, healthier yields so that you can get the most out of every harvest.

Understanding the Spectrum
Traditional LED arrays tend to mainly operate in blue and red wavelengths, the main wavelengths that activate photosynthesis. However, over-saturating plants in blue and red light puts the plants into a dormant state with high concentrations of oxygen and energy storage molecules. While this may lead to some healthy plants, you’re more often left with immature plants and low yields. Spectrum King LED grow lights are designed to mimic real sunlight to offer a full spectrum of light. This allows your plants to go through photorespiration. This essentially forces your plants to work a little harder, which causes them to want to take in more nutrients from the soil and water. The result: healthier plants and larger harvests.

Spectrum King LED Grow Lights may LOOK like Chinese High Bays on the outside, but they’ve been totally redesigned internally to produce custom supercharged LED light fixtures that maximize your plant productivity. Years of research in actual grow rooms has resulted in a light engine that features top shelf U.S. designed and manufactured components combined to produce a customized spectrum that mimics actual sunlight. Our custom drivers provide efficient consistent power and modified off-the-shelf heat sinks keep your lights cool and unit costs low, maximizing per watt productivity and overall crop quality.

With thousands of units sold the 400 Plus model is the perfect light to replace your 800-1000 watt MH / HPS bulbs.
