This standard deals with the photobiological safety of lamps and devices using lamps and includes a classification of the light source in several risk groups. The standard considers all of the photobiological hazards that may affect the skin and the eye (thermal and photochemical hazards) from ultraviolet to infrared wavelengths. Four risk groups are defined: Risk Group 0 (RG0, no risk), Risk Group 1 (RG1, low risk), Risk Group 2 (RG2, moderate risk), Risk Group 3 (RG3, high risk). The risk group depends on the maximum permissible exposure time (MPE time) assessed at a given viewing distance.

Equip your bathroom with the right light in your favorite style. A bright, glare-free lamp helps you apply makeup, shave, or brush your teeth, while ambient lighting sets the tone and boosts your mood. Choose lamps with a flair of modern art deco or a clean design with straight lines (or mix and match).

IEC 62471 defines two different criteria to determine the viewing distance. Light sources used in general lighting should be assessed at a distance corresponding to an illuminance of 500 lx. Other types of light sources should be assessed at a fixed distance of 200mm. For LED components, there is no ambiguity in the distance since LED components are not used per se in general lighting. In this case, IEC 62471 requires using a distance of 200mm. The application of the IEC 62471 measurement technique at 200mm leads to RG2 classification (moderate risk) for some high power blue and cold white LEDs.

There are certain design decisions that can be made without serious thought, such as choosing new throw pillows or a seasonal door mat. And then there are decisions like lighting, which require some practical questions and considerations to ensure you make a choice that fits your style and your needs.

The fixtures we produce as Fireflier Lighting are tested in accordance with EN 62471 standard. The products are marked according to the standards and our customers are informed about the subject when required.

The wavelength spectrum of fixtures emitting white light at different CCT values is given in Figure 1. When the wavelength spectrum of lighting fixtures (those with white light and/or narrowband radiation) is examined, it is observed that the fixtures can emit a small amount of pre-violet and/or infrared radiation. It is known that the light radiating in the given area leads to damage to the eye (on the cornea/retina) and skin. The LEDs used in lighting fixtures must be certified according to the standards that they do no cause damage to the eye and skin layer in particular in photobiological terms. According to EN 62471 which is the relevant standard of the European Union, the products radiating between 200nm and 3000nm should be subject to the tests within the scope of this standard.

Due to their unique light emission properties, LEDs are currently on the verge of becoming the dominant lighting source of this century. However, the risks posed by these new sources of light are also rooted in their intrinsic characteristics: high optical output in a small package (producing a high radiance level) associated with significant blue light emission. The combination of these two factors can potentially increase the risk of photochemical damage of the retina, in comparison with the incandescent lamp and the fluorescent lamp.

In case risk group RG1 limits are exceeded, it is accepted as risk group RG2. The radiation limits specified in the standard for risk groups are given in Table 1. The maximum exposure time for the RG2 class is 0.25 seconds. The products under this risk group are considerably bright. Therefore, sudden closure and blinking of the eye as a reflex is observed. It does not cause any damage to the retina when looking directly at the light for less than 0.25 seconds.

Exposure time for risk group RG0 is approximately 10000 seconds (~3 hours). It may pose a risk only when looking at a fixture continuously and directly for longer than that.

On the flipside, perhaps you’re looking for a single fixture for a small powder room. If the space won’t be serving as an area to ‘get ready’ for the day, you can focus more on style than practicality. Perhaps you’d even prefer a moody, elegant, softly-lit powder room?

It is interesting to note that the strict application of CIE S009 and IEC 62471 to indoor LED lamps and luminaires leads to RG0 and RG1 classifications, similar to traditional indoor light sources (fluorescent lamps, incandescent, and halogen lamps). Nevertheless, when the 200mm viewing distance is chosen, several measurement campaigns reveal that a small number of indoor LED lamps and luminaires belonged to RG2 while traditional indoor light sources (fluorescent and incandescent) were still in RG0 or RG1. This result shows that LED technology potentially raises the blue light risk in-home applications where the viewing distance is not limited and light sources are accessible to children and other sensitive people. At the time of publication, the general public remains unaware of potential risks to the eye since no mandatory labeling system is currently in place for consumer SSL products.

The notion of a safety distance would actually be more appropriate to communicate to installers and to users, especially the general public. The safety distance of an SSL product would be the minimum distance for which the blue light hazard risk group does not exceed RG1. Measurement campaigns carried out by several laboratories showed that the vast majority of indoor LED lamps and luminaires have a safety distance of 200mm which is compatible with most lighting applications.

Fireflier Lighting factory is well aware of the photobiological safety of their products. Many lighting products using LEDs now emit warmer shades of white light (reduction of the blue light content in the spectrum) or use diffusers to reduce glare (reduction of the radiance). Most lighting products are found to present low risks or no risk at all for the general population when the viewing distance is equal to or greater than 200mm.

Equip your bathroom with the right light in your favorite style. A bright, glare-free lamp helps you apply makeup, shave, or brush your teeth, while ambient lighting sets the tone and boosts your mood. Choose lamps with a flair of modern art deco or a clean design with straight lines (or mix and match).

It is important to note that other widely used lighting sources, particularly high-intensity discharge lamps used for outdoor lighting are in RG2 (moderate risk). However, these lamps are intended for clearly identified uses and can only be installed by professionals who should be aware of the safety distance required to limit the exposure.

The maximum exposure time to RG1 armatures is 100 seconds. Exposure to a direct light source for less than 100 seconds under ordinary conditions of use is not considered hazardous.

If you’re shopping for bathroom lamp fixtures for a main bath or primary bedroom bath, you and your family will likely be using the space for bathing, brushing your teeth, combing your hair, putting in contact lenses and more. If that rings true, you’ll want to be sure you have proper lighting to accomplish all those tasks.

However, the choice of the viewing distance in IEC 62471 is sometimes ambiguous and not realistic in the context of the real usage conditions. For instance, in the case of stage lighting (theatres, concert halls) where artists are exposed to an illuminance level higher than 500 lx. Applying the 500 lx criterion would underestimate the exposure while the 200mm criterion would largely overestimate it. In a more usual situation, directional household lamps fall under the 500 lx criterion, which corresponds to a typical viewing distance of a few meters. It is however quite common to have shorter viewing distances, as short as 200 or 500mm at home. Another example is street lighting where the illuminance level is much lower than 500 lx, typically a few tens of lx. Assessing the exposure to blue light emitted by a street lighting luminaire at the distance giving an illuminance of 500 lx is clearly not appropriate. A future revision of IEC 62471 should bring a more accurate definition of the distance at which the risk group is determined.

The current EN 60598-1 standard concerning general lighting fixtures shows that RG0 or RG1 risk groups are acceptable for safety purposes. It is not suitable to use light sources with a higher degree than RG2. There is no need to mark the fixtures with risk group RG0 or RG1. When RG2 limit condition 2 is reached, the limit distance must be calculated according to IEC/TR 62778 (see article 5 of this document). If the distance is higher than 20 cm, the requirements below are recommended:

The total amount of light needed in a space can vary quite a bit from bathroom to bathroom based on a number of factors, including the amount of natural light the bathroom receives and whether it’s used for personal grooming.

When performing lighting design, the use of lighting products and lighting fixtures that comply with the relevant safety and performance standards should be taken as the basis.

In solid-state lighting products such as LEDs, LED modules, LED lighting fixtures, etc., the photobiological safety standard must be necessarily applied against the damage of light to the eyes and skin and the blue-light hazard.

Whether you’re updating current fixtures or designing a whole new bath, it’s important to first consider how many total fixtures you need and where they’ll be located. Many of our styles are flexible and look great in a variety of locations and configurations, while others are best suited for ceiling placement and beside or above a mirror.
