Spectrum King
-
Spectrum King is the first company to provide Full Spectrum LED grow lights to both the commercial and home growing community. We design our LED grow lights to mimic the sunlight because that is what plants need. Unlike other LED grow lights, SKLED distances their competitors by having one of the largest PAR ranges, as well as high lumens count. Plants need more than just ultraviolet or red light; they need the Full Spectrum of colors for their grow cycle (including Blues, Reds, etc.).
Unlike other grow lights and bulbs, Spectrum King's full spectrum grow lights supply the plants all light they need. Also, they do not get hot (saving money on both AC and maintenance), while protecting the environment from pollution. If you grow with HPS grow lights (an old technology), you know how much money must be allocated to your electricity bills! When you change to Spectrum King LED lights, you will get higher yields for less expense, whether you are a commercial or home grower.
When you choose to grow with inexpensive/lower quality LED grow lights, or even ONE color LED grow light you will notice the difference when you change to Spectrum King LED and get much better yields in your commercial and home grows.
Numerous measures of light intensity in the LED industry has led to consumer confusion. Choosing the right LED grow light with a can be complicated, especially with all the scientific calculations and data that lighting companies are using to market their products. Consumers struggle with complex math and lighting measurements which are very different from traditional growing technologies and calculations. The average consumer is neither a botanist nor a lighting engineer, so understanding the different spectrums, units of measure, and the correct instruments to read them is difficult. Additionally, the horticulture/agriculture industry has expanded from the traditional two (2) light spectrums to over twenty in efforts to mimic sunlight in LED. Traditional proven spectrums are no longer the norm for high lumen LED grow light companies who have seen the benefits of full spectrum LED grow lights.
Proven Past
Traditional bulb manufacturers used a spectrum graph along with Lumens, LUX and PAR values when marketing their products. Today, LED grow light companies use complex units of measure such as Umol per second, YPF, PPFD/w, and Umols per joule. These spectrums are very different than that of traditional proven lamps, creating confusion with the average consumer.
Quality vs. Quantity
LED grow light selection has become as important as the quantity of lights purchased. Grow operations have witnessed capital expenditure in LED quantity instead of light quality, resulting in lower productivity. This consumer perception of LED failure has resulted in many grow operating reverting back to traditional HPS lighting. Furthermore, the lack of LED industry technical standards has contributed to this uncertainty in light selection and its correlation to yield.
Shining Some Light On LED Confusion
Modern grow operations use either metal halide (MH) or high pressure sodium (HPS) bulbs, which can include double ended (DE) lamps. These light sources have historically proven technology and spectrums, and hence have remained the number one choice for grow operations worldwide. Growers tend to use bluer spectrum MH lamps for leafy green vegetation, and warmer tone HPS lamps for flowering plants and food production (reference image # 1).
Bulb companies tend to advertise the spectral output, total lumen output, and radiant flux of their lamps on their packaging. This visual spectrum, typically between 400-700nm, is the same range as photosynthetically active radiation (PAR) which is used to measure the photon energy absorbed by plants. Both measurements use different calibration methods and both are typically on product labels these days.
However, the LED grow light industry has been marketing different units of measurement, namely PAR, Umols/second, Umols per joule and PPFD/watt. As a result, units of measurement such as Lumens and LUX are being phased out.
Did you know that foot candles, Lux , lumens and PAR all measure the same spectral range of 400-700nm which is visible light!!
