Full-spectrum light copies the light spectrum of natural daylight. However, there is no full-spectrum light bulb, and it is said to be more of a term used to attract customers' attention. This is because no light bulb can completely imitate daylight. To achieve this,
Spectrum is seen as light stretched out into a rainbow of colors. Light is measured in nanometers, and every nanometer represents a wavelength of light. The various wavelengths of light appear in different colors causing colors to be interpreted.
The light bulb spectrum refers to the range of visible light produced by the light bulb. The visible spectrum ranges from shorter wavelengths (red) to longer wavelengths (blue). These are the two extreme ends of the spectrum.
The incandescent light bulb spectrum range is referred to as a continuous spectrum. Just like the sun, all colors are represented. However, for the fluorescent bulb and LED bulb, their light spectrum is known as the emission spectrum because the wavelengths are on a punctuated line. As a result, not all colors are caught with this light source. Every light source has its spectrum because they all have different characteristics.
There is no clear definition of full-spectrum light bulbs, and this has allowed some inclusions, like the application of the term in defining plant grow lamps, color matching lamps, and aquarium lamps. Some people also say that a bulb must radiate ultraviolet rays to be classified as a full-spectrum light. However, there are two primary full spectrum light bulb types - incandescent lights and fluorescent lights.
Generally, these bulbs are used where there is a need to use lighting that is close to the natural. Some of the expected benefits of full-spectrum lights are:
Using these bulbs serves as a replacement for the daylight. Some psychologists advise SAD patients to spend a considerable amount of time under the full spectrum of light. Thus, full-spectrum light might be a good choice for people affected by the winter.
The daylight bulb and full spectrum bulb are sometimes confused for one another. The difference between both lights is in their characteristics and functions.
A daylight bulb is similar to natural daylight in its color temperature. It provides between 6000k - 6500k color temperature and a Color Rendition Index of about 80%.
On the other hand, the full-spectrum bulb produces the full range of the color spectrum. It captures both visible and invisible color wavelengths of light. This means it can identify distinct colors that daylight bulbs and other light sources cannot. The full-spectrum bulb gives the closest benefits to natural daylight. Its color temperature is between 5000k to 6500k, and the Color Rendition Index is above 95% giving off a perfect color interpretation.
So, while daylight bulbs give a feel of daylight, full-spectrum bulbs imitate daylight in its functions like color interpretation and health benefits; thus, it is the closest light source you can have to daylight. However, if you are going for either one for their aesthetic benefits, you can go for the daylight bulb since it's cheaper.
Full-spectrum light bulbs are light sources that imitate the light spectrum of daylight. Although they do not fully measure up, they are the closest to daylight's spectrum. These light bulbs try to achieve a color rendering close to the sun and provide a color temperature similar to daylight.
TrueWave™ technology is one product that provides excellent natural lighting. Its products have a balanced spectrum, providing a brilliant color rendering of objects without sacrificing the light output. This makes TrueWave one of the best options when purchasing full-spectrum lights.
