How safe is UV-A LED Light?
I am considering realUV™ LED Strip Lights in a custom bookshelf to make some vaseline glass fluoresce. I read on your site that 365nm is better than 395 for this application. How safe is UVA? I thought about putting the fluorescent items and LEDs behind the glass (which I know *passes* UVA) and applying a UV-blocking film to the glass which would pass the visible fluorescence. Is this kind of protection necessary? Is there a distance from the LEDs where the amount of UVA hitting a person would be negligible?
Our UV-A LED strips sound like a great fit for your vaseline glass fluorescence project!
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 close to 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.
UV exposure is usually not an issue as long as a reasonable distance is kept between the UV source and human skin and/or eyes, and as such, we do not anticipate any significant safety risks arising from the proposed installation. We recommend consulting a UV safety expert if you have any further concerns.
