I feel like there has been a ton of info on ultraviolet light lately as a germicidal method. I just ran across an article giving a review on this little mini-UV class C light that sanitizes surfaces:
Okay, now is it me, or is that lady way too happy to be using her mini-wand on the ol' porcelain throne? She is thrilled! Using the Germ Guardian UV-C Mini Sanitizer Wand is not only good for killing bacteria, but it must be a hoot too!
Simply pass the Germ Guardian Mini Sanitizer Wand over surfaces to kill up to 99% of bacteria and viruses. Also fights unwanted odors and allergens like mold spores and dust mites. Ideal for – toilets, showers, phones, computers, sinks, countertops, bedding and shoes. Take it with you when you travel!
I guess it's pretty easy to use – button on, button off operation, and it's good on batteries. It has a safety device in it that turns the lamp off if it's tilted up – probably to prevent eye damage – which, according to Scott Merrill over at CrunchGear, was kind of a pain in practice although a good idea in theory.
Gosh, even I'm excited for the lady nuking that toilet!
