A startup company in Troy, NY founded by a couple of Rensellear Polytechnic grads has come up with a white light LED fixture that includes a blue-violet wavelength that kills gram-negative bacteria. The fixture isn't that efficient (around 25 lumens/watt) compared to other LED fixtures, but if it performs as claimed, it could be a boon for the health care and food processing industries.

They're currently manufacturing the fixtures themselves out of a Makerspace lab in Troy.

I like these guys.

Could be something but then we'll start having to deal with blue-violet wavelength resistant gram-negative and gram-positive bacteria maybe?

Looks like another human weapon for the war against biological nasties.

Interesting question. Hospitals have traditionally been using shortwave UVC fixtures for disinfection; I don't think this causes resistant bacteria to grow, probably because UVC is nasty enough to break down the molecular bonds in the germs. I don't know whether UVA exposure works the same way on the bacteria that they're aiming at.
