Spectrum King 400+ LED Grow Light - Full spectrum equivalent to 1000W HPS

At Grown Up Hydroponics, we've been waiting years for the right LED light to reach the market. We've tested numerous models but never been happy with the results, until now! The Spectrum King LED Grow Lights are truly "Next Generation".

Like us you are probably used to the purple LED's that don't emit full spectrum light and have poor penetration. Thankfully that has now changed with the release of the Spectrum King 300+ and 400+.

The Series 400+ Spectrum King is for light hungry plants and comparable to a 1000w HPS.

Spectrum King LED Grow Lights are designed and manufactured by experienced LED professionals who have been creating custom industrial LED Lighting solutions for various industries, including medical, government, military, commercial, and agriculture for over 10 Years. And best of all They're also growers! So we truly understand the value of efficient lighting from a grower’s perspective and what is required to produce an outstanding harvest.

Why Full Spectrum?

Spectrum King LED Grow Lights are designed to mimic natural outdoor sunlight. Why change what Mother Nature has already perfected over millions of years? Sunlight includes many spectrums, both visible and ones we cannot see; even traditional HPS lights put out a high band of nano-meter wavelengths (colour spectrums) which is why it has been successful in the agriculture application today. LED grow lights that provide only 2, 3, 4 even 8 colours will never come close to reproducing the effects of sunlight.

Spectrum King LED Grow lights consistently produce spectrums from 380-779nm. This means that not only virtually every visible colour is present in the light, but also ones you can’t see. The Spectrum King Series 300 and Series 400 LED Grow Lights truly mimic sunlight and traditional HPS lamps with matching intensities of over 100,000Lux.

We all know that blue and red are the wavelengths that dominate the “active photosynthesis” portion of the spectrum, so you might think that providing these colours alone might circumvent the rules of nature. But there is a problem: Productive plants need to photo-respirate. When plants become heated (by intense yellow light) the stomata on the leaf surfaces open up and allow photo-respiration to occur. When photo-respiration takes place the plants go into “work out” mode and want to consume nutrients just like humans want to drink water.

Traditional LED arrays only carry the spectrums that activate after the photo-respiration period takes place. This is the reason traditional LED lights sometimes finish cycles with immature plants that produce low yields. By supplying plants with only limited “beneficial” spectrums (pink light) from traditional LED arrays, you are essentially putting them into a permanent chill mode. Although this may produce healthy plants, they will not yield as much as plants under Spectrum King LED Grow Lights.

  1. Day light review by LED lover on 02/10/2015

    No more purple light.

    The price is high but the quality is too.

    The penetration is amazing and wear sunglasses or it's all you'll see for the rest of the day. 440 watts!

    Build quality is good, really sturdy and completely washable.

    5 year warranty was the deciding factor. Electrical savings and no bulb buying is pretty good as well.
