Spectrum King LED Grow lights consistently produce spectrums from 380-779nm. This means that not only virtually every visible color 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 colors 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.
LOWER TEMPS AND POWER DRAW SAVE YOU MONEY
While HPS lights require over 1,000 watts to produce the intensity needed for healthy plants, Spectrum King LED Grow lights do the same using only 450 watts. This allows growers to save on electricity and benefit from lower ambient temperatures — which translate to less A/C usage and expense.
SEALED WATERPROOF HOUSING
In a grow room, cleanliness is an important factor. Unfortunately, at times gardens can be infested with bugs and other insects — even soil and dust. Many of today’s LED lights have fans for cooling. But cooling fans also have a down side: bugs get sucked in and so does moisture from humidifiers and misters. The LEDs get covered with sticky “garbage” and over time lose cooling and even light performance.
Spectrum King LED Grow Lights are IP65 rated, which means they are completely sealed from dust and moisture and can even be washed with a garden hose!
