Bril

Answer: Hello, When charging the light will turn green to indicate a full charge. At a general level, there is ample data to show that UV-C wavelengths like those used in Bril, are effective for sterilization. Here's some evidence: https://www.fda.gov/medical-devices/coronavirus-covid-19-and-medical-devices/uv-lights-and-lamps-ultraviolet-c-radiation-disinfection-and-coronavirus For our product specifically, we have independent lab test results showing Bril's efficacy against various bacteria like Staph, Strep, and E. Coli. Every single test showed at least 99.9% of the bacteria were neutralized. As you read about UV-C light, you may be concerned about the effects it can have on your skin and eyes. Part of what makes Bril a higher quality product, and contributes to the cost of production, is the fact that we specifically sourced medical grade glass, that doesn't allow the harmful UV-C waves through, for the viewing window. In short, if you can see the blue light on in your Bril, you can be sure that you are safe and the germs on your brush are not.

Answer: Martha, Addressing your question directly, no, the blue light not lighting does not mean the device is not working. Bril uses ultraviolet (UV) light to sanitize the toothbrush and the ultraviolet wavelengths are invisible to the human eye. Because of that, a regular blue LED light was added as a mere indicator. That means it's possible the UV light is still functioning fine even if the blue light has somehow stopped working. They are not one in the same. That being said, you should definitely contact customer service about your device and they'll take care of you.
