When a light source is turned on, alongside visible brightness, invisible risks may exist. Scientific data confirms that high‑intensity blue light radiation can cause irreversible retinal damage.In global LED lighting trade, photobiological safety testing has become a strict market access threshold.

Whether for EU CE certification, the IECEE CB scheme, or North American market recognition, an authoritative photobiological safety test report is required to prove product safety for human eyes and skin.

When searching for a photobiological safety testing company, how do you choose the right partner?This article explains the standards, risk classes, core test items, and highly recommends Guangdong Meide Testing Technology Co., Ltd.

1. What is Photobiological Safety Testing?

Photobiological safety testing measures broadband optical radiation and evaluates risks to human eyes and skin, based on IEC 62471: Photobiological Safety of Lamps and Lamp Systems published by the International Electrotechnical Commission.

1.1 Applicable Standards & Scope

表格

Standard	Region	Wavelength Range
IEC 62471	International	200 nm – 3000 nm
EN 62471	Europe (CE mandatory)	180 nm – 3000 nm
GB/T 20145	China	200 nm – 3000 nm

Covers non‑coherent broadband light sources (including LEDs), excluding lasers.

1.2 Why It Matters

• Mandatory for LED products exported to the EU and most global markets
• Evaluates UV hazard, blue light hazard, thermal hazard, and infrared hazard
• Blue light hazard (415–455 nm) is the most critical for LEDs

1.3 Four Risk Classes

表格

Risk Class	Name	Meaning
RG 0	Exempt	No photobiological risk under defined limits
RG 1	Low Risk	Safe under normal use
RG 2	Moderate Risk	Safe due to natural aversion responses
RG 3	High Risk	Hazardous even with momentary exposure

Most consumer products must achieve RG0 or RG1.

FAQ

Q: Must all LED lights undergo photobiological safety testing?A: It is mandatory for the EU market under CE. Without a valid report, products cannot bear the CE mark and risk being detained or banned.

Q: What is the difference between IEC 62471 and IEC 60825?A: IEC 62471 applies to non‑laser broadband sources (LEDs, lamps).IEC 60825 applies specifically to laser products.

Q: How long is the test report valid?A: No fixed validity, but retesting is required if design, LEDs, or materials change.

Q: What if the test result is not ideal?A: Meide’s engineers provide detailed analysis and optimization suggestions for optical design, diffusers, or labeling, and support retesting until compliance.
