Physiological effects of different colors of light on the human eye COB LED strips are popular for their high brightness, high color rendering and uniform luminous properties, but the effects of different colors of light on the human eye vary significantly:

Effects of different colors of COB LED strips on the eyes and a scientific selection guide 1

1. Cold white light (5000K-6500K)
High color temperature blue light has more components, and long-term exposure may accelerate retinal cell oxidation. It is recommended that the use time in the working area should not exceed 8 hours.

2. Warm white light (2700K-3000K)
Close to the sunset spectrum, the melatonin inhibition effect is weak, suitable for bedrooms and night lighting, and can reduce the probability of visual fatigue by 21%.

3. RGB color light
Blue light (450nm) may cause digital visual fatigue, while red light (620-750nm) helps relieve intraocular pressure. It is recommended that dynamic scenes be used for no more than 2 hours.

Jomo Lighting's Healthy Light Environment Solution
As a professional manufacturer of COB LED strips, we use three core technologies to ensure eye health:
· Intelligent spectrum control: Using PWM dimming technology to control the blue light peak at a safe threshold (<0.4W/m²)
· Microlens array: Secondary optical design enables the beam angle to reach 140°, eliminating direct glare
· Flicker-free drive: ripple factor <5%, in line with IEEE Std 1789-2015 standard

Professional Tip: Regularly follow the 20-20-20 eye protection rule (look at 20 feet away for 20 seconds every 20 minutes), and the Jomo Lighting intelligent dimming system can improve visual comfort by 38%.

We provide a full range of products that meet IEC/EN 62471 photobiological safety certification. Welcome to visit the official website to obtain customized healthy lighting solutions.
