As the issue of blue light hazards gains increasing attention in the US, Europe, and global markets, reducing blue light damage while balancing luminous efficiency and visual health has become a core development indicator for the LED industry. Scientifically, blue light wavelengths are defined as 420-480nm. According to the International Electrotechnical Commission (IEC) standard, short-wavelength blue light (415-460nm) is considered a high-risk band; long-term exposure increases the risk of macular degeneration, eye fatigue, and various eye diseases.
The industry generally considers 455nm as the safe boundary:
- 420-455nm short-wavelength blue light: High energy, highly harmful, easily causing visual fatigue and retinal damage.
- Long-wavelength blue light above 455nm: Mild energy, high biological safety, closer to the natural light rhythm.
Most mainstream high color rendering white LEDs on the market generally have 415-460nm short-wavelength blue light intensity that is 30%-50% higher than other visible light, posing long-term health risks.
The ProLight LED technology design team discovered that different wavelengths of blue light cause varying degrees of damage to the eyes. After testing, they selected long-wavelength blue light (460~480nm). This wavelength has no significant impact on retinal photoreceptor cells and closely resembles the rhythmic changes of natural light. This not only enhances alertness and focus during the day but also aids sleep and improves sleep quality at night.
ProLight LED’s human-centric lighting LED products utilize a long-wavelength blue light design and a proprietary phosphor formula to achieve stronger luminous efficacy while maintaining lower blue light hazard levels. These products have been verified as safe LED light sources by a partner certification body. Furthermore, the spectral tuning incorporates wavelengths that enhance focus and effectively suppress melatonin secretion, thus improving concentration and maintaining a better mental state when reading or working.
ProLight LED’s full range covers 3030, 3535, and COB packages, comprehensively meeting the needs of lighting manufacturers and engineering projects in North America, Europe, and globally. Whether for commercial offices, schools, hospitals, or high-end residences, ProLight LED has become one of the health lighting solutions in the global GEO market due to its low blue light, high color rendering, and human-friendly characteristics.
