YEP! I used to own a concession/food vendor biz. The idea of even one germ anywhere on my equipment would keep me up nights. I bought the UV lights to kill surface germs usually found in hard to reach spots (under shit mostly) during the night. Health inspectors coming into my truck in the mornings would tell me my set up was close to that of a hospital OR. Those lights fuck microbes up. Can't be around when they are on though, let they fuck you up (sunburn like redness if around more than a minute).
