Since the concept of LED lighting has entered our lives, we have started to learn very different terms. One of them is the “full spectrum”. Some manufacturers state that their LED lighting products emit full spectrum light. So, what is full spectrum?

Full spectrum is a kind of lighting, covering all wavelengths useful for plants and animals. Even though the part of the sunlight reaching the earth changes according to time, latitude and atmospheric conditions, sunlight is accepted as a full spectrum.

The full spectrum concept on LED lighting products on the market is far from being a technical term. It is usually used to indicate the natural light quality of the product. Products marketed as a full spectrum can produce light throughout the entire visible spectrum. However, it cannot provide this with an evenly equal spectral distribution.

Full spectrum lamps are generally used in art galleries, aquariums, gardens and indoor plant growing. However, this is not the most efficient type of lighting.

Because full spectrum lights simulate sunlight, there is a thought that its use in daily life is beneficial. However, it is not true to say that such lights are healthier than other electric light sources.

Full spectrum lamps simulate natural sunlight and produce high brightness light. However, long exposure to this light can cause adverse effects, since these lamps also have an amount of blue light, which is the short wavelength of the light spectrum.

Light is the most important environmental exciter to regulate circadian rhythms. Exposure to sunlight during the day and light that stimulate sunlight in the evening can cause sleep problems. In the evening, it is better to use warm light sources which contain less blue light.
