Eye safety for realUV LED strip lights
I was wondering under what conditions either the 365 nm or 395 nm realUV LED strips could present an eye safety hazard. Are there viewing conditions that could be hazardous with a short LED strip segment?
Generally speaking, it's a bit difficult for us to provide assurances and guarantees regarding the safe use of ultraviolet LED products, as each installation and application can vary significantly, so we recommend consulting a UV safety expert if you have specific concerns.
Both the 365 nm and 395 nm wavelengths fall under the UV-A wavelength range, which is a weaker form of ultraviolet radiation that is found in natural daylight so there are fewer concerns than other ultraviolet products that fall under the UV-B or UV-C wavelength ranges, for example.
That being said, below are some general safety guidelines that we would recommend following:
- The ultraviolet emitters have a very high intensity when used at a very short distance, but less so at longer distances. Therefore, ensuring that people or animals do not come near the UV source can help reduce the risk of any eye safety issues.
- Ultraviolet energy is mostly invisible to the naked eye. It can be difficult for the vision system to recognize a high level of UV "brightness" and produce a natural response to squint or look away, in the way that natural white light would.
The use of a short segment should present a relatively low risk given their correspondingly low energy output. We would recommend ensuring that the LED strip lights are pointed away from any people, and perhaps install them as far away from eye level as may be practical.
