How do you choose lighting for your children's study environment or living room? While it's easy to think "brighter is better," the quality of light actually significantly impacts eye health.

What is the Impact of Blue Light on the Eyes?

Blue light (short-wavelength light between 380-500nm) emitted from LED lighting and digital devices can easily reach the retina and may cause eye strain and decreased sleep quality with prolonged exposure.

Especially for children during their growth period, whose crystalline lenses are transparent, more blue light reaches the retina than in adults, making it crucial to consider the lighting environment.

Blue Light Safety Standard for Lighting: "RG Classification"

The blue light risk of lighting fixtures is classified by "RG Risk Groups" based on the international standard IEC 62471.

  • RG0 (Risk-Free) — No risk to eyes even with prolonged use
  • RG1 (Low Risk) — Safe under normal use
  • RG2 (Moderate Risk) — Safe due to aversion response

lipro ceiling lights have obtained the highest RG0 certification, making them a safe lighting choice to protect your children's eyes.

Color Rendering (Ra Value) — An Indicator of Light Quality

Color rendering refers to how naturally a light source reproduces colors. Sunlight has an Ra value of 100, and the closer a light source's Ra value is to this, the more natural colors appear.

  • General LED lighting: Around Ra80
  • High color rendering LED: Ra90 or higher
  • lipro Ceiling Lights: Ra97

Such a high color rendering of Ra97 makes a noticeable difference in various daily situations, such as fostering children's color perception development and accurately discerning food colors.

Impact of Flicker

Lighting flicker, which is often imperceptible to the naked eye, can also cause eye strain and headaches. lipro ceiling lights feature a flicker-free design compliant with IEEE standards, ensuring comfort even during long hours of studying or reading.

3 Key Points for Choosing Eye-Friendly Lighting

  1. Check Blue Light Safety Rating — Choose RG0 certified lighting.
  2. Color Rendering Ra90 or Higher — Lighting closer to natural light reduces eye strain.
  3. Flicker-Free Design — Choose products compliant with IEEE standards.

lipro meets all three of these points with its proprietary technology achieving "94.86% Sunlight Reproduction Rate." It is a trusted brand with over 5 million units sold and has received international design awards such as the iF Design Award, Red Dot Design Award, and Kids Design Award.
