Difference between Full-Spectrum LED Light and Ordinary

Mar, 22, 2022

First, let's take a look at the following pictures. It's obvious that foods on the left are more attractive than that on the right. What makes this difference?

Well, the left is effect under full-spectrum LED light, while the right is effect under ordinary LED light. As full-spectrum LED light provides better visual performance than other ordinary LED lights, we can see that the most obvious difference between them is that colors of the things under full-spectrum LED light are closer to their original colors. CRI of full-spectrum LED light is higher than 80% which is why full-spectrum LED light is increasingly popular in the market. CRI of Signcomplex LED strip can reach up to 97, which makes colors more realistic.

So, what is full-spectrum light?

Full spectrum led light strips are light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions. Full spectrum strip lights emulates some important quality of natural light.

Scientific research has found that light, as one of the main driving forces of the human circadian system, whether it is natural sunlight or artificial light source, will trigger a series of circadian reactions. Light affects human health to varying degrees through visual and non-visual effects.

Benefits of sunlight

As we know, sunlight has many benefits. For example, first, exposure to the ultraviolet-B radiation in the sun's rays causes a person's skin to create vitamin D. The vitamin D made thanks to the sun plays a big role in bone health. Second, a moderate amount of sunlight has preventive benefits when it comes to cancer. These cancers include: colon cancer, Hodgkin's lymphoma, ovarian cancer, pancreatic cancer and prostate cancer. Third, according to the World Health Organization (WHO), sun exposure might help treat several skin conditions, too. Doctors have recommended UV radiation exposure to treat: psoriasis, eczema, jaundice and acne. Therefore, except improving visual clarity, full-spectrum LED light which emulates sunlight also aims at improving people's psychological and physical health.

Therefore, advocating "healthy lighting" and improving light quality and comfort are very important. The so-called "healthy lighting" can improve conditions and quality of people's work, study and life, and promote psychological and physical health through lighting.

Comparison of advantages and disadvantages of full-spectrum LEDs and ordinary LEDs

Advantages of full-spectrum LEDsDisadvantages of ordinary LEDs
Reduce the damage to retina.The peak value of the blue light band is too high, causing damage to the retina.
Make colors more realistic (referring to the typical daylight D40 spectrum, the purple, blue, green, and red portions of visible light band are complemented).Colors are not so realistic (due to non-compliance with D40 spectral distribution).
More comfortable compared to ordinary light when reading books (because human eye has a higher sensitivity to red light, and in the full-spectrum light source, the spectral component of red light is close to D40).Easier to cause eye fatigue when reading books for a long time, causing adverse effect on vision.

With the continuous development of LED lighting technology, LED technology (full-spectrum technology) similar to solar spectrum has been realized and is being applied in the industry. Signcomplex is also committed to developing more led strip light in Chinaled grow light wholesalecommercial led lighting that are good for health.
