With concerns about the transmission of COVID-19 at the forefront of society’s collective consciousness, UV light—especially the UV-C range—has been put forth as a possible solution. But how does one produce UV light indoors? UV LEDs of course!
For this purpose, prolific Tindarian Bobricius has come up with an LED module with a single 275nm UV-C light onboard. It includes the proper resistor to keep it functioning properly via a 9V power source, making it easy to implement.
While it may be effective, the listing notes that it is untested on viruses and bacteria. You’ll of course want to use it appropriately based on that information, and also note that it can be harmful to skin and eyes.
So why then did Bobricius make this contraption? As in so many works of science fiction, he had been dreaming of a radiation killing module. Now perhaps such a device can be used for good. Notably, there is a significant discount for orders of more than one, so perhaps a “killer array” would be a better option than a single source of radiation in this case!
Of course, makers aren’t just on the germ-offensive these days. As seen here, there’s been a huge push to produce PPE, especially during early shortages of a few months ago.
