Spectrum King’s Phoenix 840W is great for photon-hungry crops that can handle intense light. Drawing 16% less power from the wall than a standard HPS fixture, the 840 brings some serious output while still saving on electricity and heat compared to other fixtures.
SK Cryo-Therm cooling technology enables an ultra slim form factor, allowing for maximum airflow and minimizing micro-climates. Optimized for single or multi-tier cultivation in proximity to the canopy.
If your crops need mega brightness, the Phoenix 840 is a fixture that delivers.

Spectrum King LED’s full spectrum LED grow lights are designed to mimic the quality and intensity of natural outdoor sunlight, helping your plants grow healthier and yield better harvests.
Natural Sunlight includes all spectrums, even beyond what we can see with the naked eye, such as ultraviolet and infrared. Traditional high pressure sodium (“HPS”) lights emit an intense high band of limited nanometer wavelengths (yellow light). This activates photorespiration, which is why they have been successful previously in agricultural applications. Our full spectrum LED grow lights provide the full array of colors found in sunlight, outperforming anything that an HPS light can accomplish. With Spectrum King LED No matter what species or genetic you grow under our light, it will succeed without having to second guess the spectral output. Why change what Mother Nature has already perfected over millions of years?
Spectrum King LED’s full spectrum LED grow lights consistently emit wavelengths in the range of 380 to 79nm. This includes those wavelengths visible to the human eye (what we perceive as color) and the invisible wavelengths, like ultraviolet and infrared. Our LED grow lights truly mimic natural sunlight, while matching intensities of traditional HPS lamps.
We know that blue and red are the wavelengths that dominate “active photosynthesis,” so you might think that providing these colors alone might circumvent the rules of nature. However, there is a problem: productive plants, whether they’re on a farm or in nature, need photorespiration. When plants become heated by intense yellow light like HPS or natural sunlight, the stomata on the leaf surfaces open up to allow for photorespiration. During photorespiration, the plants go into “workout” mode, which causes them to consume more nutrients just like humans want to drink water or eat after a session at the gym. This translates into growth and a healthier harvest.
Many LED arrays tend to only emit the spectrums that activate after the photorespiration period takes place (grow lights with dominant red and blue LEDs). This is the reason traditional LED lights sometimes finish cycles with immature plants that produce low yields. By supplying plants with only the limited “beneficial” spectrums (pink light) from traditional LED arrays, you are essentially putting them into a permanent chill mode.
You may end up with some healthy plants, but they will not have high yields or be as healthy as plants under a full spectrum LED grow light. It’s obvious if you think about it – if red and blue light were truly all that plants needed, then why do HPS lights which don’t have much of either color outperform them? The answer is intensity. Plants crave intensity first, followed closely by spectrum. When you give your plants both intensity and full spectrum light, like a Spectrum King LED fixture can provide, they will pay you back every time.
