5000K CFL – Answering Common Questions About Full Spectrum Light

What is natural full spectrum light? You hear the term full spectrum light thrown around a bit too often. You can find a 5000K CFL at very affordable rates. However, natural full spectrum light is not quite the same as light bulb full spectrum. Natural light coming from the sun carries several different types of spectrums. The waves go from infrared to near ultraviolet. Those waves are beneficial for all forms of life on earth. Plants and animals use these light wave lengths for a number reasons. Manufacturers of light bulbs want to replicate those wave lengths.

What is the difference between natural and bulb-generated full spectrum light? Grow bulbs-generate full spectrum light is hard to define. Light bulbs use a variety of materials to generate light. It often involves heating up a specific element or a combination of elements that will emit light as part of the heating process. Each element or element combination will put off different types of light. In this type of bulb, there is no way to measure the color temperature. Instead, they use the concept of spectral power distribution. The higher the number, the wider the spectrum of energy will be. For example, 0K is black. A 5000K CFL bulb, on the other hand, is close to the noon day sun.

What are the uses for a bulb with all colors, blues, yellows, and oranges? Most people associate full spectrum lamp for one of two uses: growing plants indoors and phototherapy. Growing plants inside is challenging, especially in the winter. Many want the option of overwintering plants or starting seedlings early. In both cases, using this type of light will help. Phototherapy involves exposing the skin to complete lighting sources during the winter. Some people go through season depression as winter emerges. With light boxes, they can avoid some of the problems. Many use a 5000k CFL bulb as part of their light box.

How do you measure full spectrum light? Most of the time, scientists will use the color temperature and color rendering index to measure light. However, that depends on a single wave length of light. A source of this type offers multiple types of waves. In order to measure this, manufacturers use the spectral power distribution of heating one cube of carbon. At 0K, the glow it emits is black. At 5000 to 5500 K, the light it emits is close to what the sun does at noon. Therefore, a 5000K CFL bulb is very close to the sun in spectral power distribution.
