Can the LED Wall Light on the market that claims to protect the eyes really protect the eyes?

In recent years, LED Wall Light has quickly become a popular choice for home and office lighting with promotional labels such as "eye protection", "low blue light" and "no flicker". However, faced with a wide range of products on the market, consumers can't help but wonder: Are these LED wall lights that claim to protect the eyes real science or marketing gimmicks?
The key to eye protection: spectrum and flicker
Real eye protection lighting must meet two core standards: low blue light hazards and no visible flicker.
Blue light hazards: Excessive short-wave blue light (400-450nm) in LED light sources can interfere with the secretion of melatonin in the human body, and long-term exposure may cause visual fatigue and even retinal damage. The international standard IEC 62471 divides blue light hazards into four levels from RG0 (no risk) to RG3 (high risk), while some low-priced LED lights on the market are only marked with "low blue light" but have not passed the RG0 certification.
Flicker problem: Flicker is caused by current fluctuations. Although it is difficult to detect with the naked eye, long-term use of the eyes in a flickering environment can easily cause headaches and blurred vision. IEEE (Institute of Electrical and Electronics Engineers) recommends that the flicker percentage must be less than 8% to be qualified, while many LED wall lights use low-cost PWM dimming technology, with a flicker rate of more than 30%.
Three major traps of products on the market
False labeling: Some products claim to be "blue light-free", but in fact they only weaken visible blue light through filters, but do not reduce the energy output of harmful bands, and even increase the overall blue light ratio due to brightness compensation.
Inferior chips: Low-priced LEDs use chips with low color rendering index (CRI<80), and the natural spectrum is missing in the light, resulting in color distortion and increasing the burden on eye adjustment.
Pseudo-eye protection design: RGB color light strips simulate a "soft effect" by mixing white light, but the messy combination of color light will stimulate the pupil to contract frequently, which is counterproductive.
Scientific eye protection solution
To choose a truly eye-protecting LED Wall Light, you need to pay attention to the following three points:
Certification and data: Look for RG0 blue light certification, IEEE flicker standard (percentage <5%), and require merchants to provide third-party test reports.
Full spectrum technology: high-quality lamps simulate the continuous spectrum of sunlight (CRI ≥ 95), reducing eye pressure caused by spectrum loss.
Intelligent dimming: Support DC dimming or hybrid dimming technology to ensure smooth brightness changes without flicker, and the color temperature can be adjusted to 3000K-4000K warm white light, close to natural morning light.
