315 – 400 nM range for Germacidal lamps. the 254 nM range is good for killing bacteria.

I am looking for the Nm that one would need for an LED light to kill any bacteria or soft bodied pest.

While i really like this product I think I could use it in my main work as a nurse. I do not believe it will kill the really nasty bugs such as MRSA.
” MRSA is a resistant variation of the common bacterium Staphylococcus aureus. It has evolved an ability to survive treatment with beta-lactamase resistant beta-lactam antibiotics, including methicillin, dicloxacillin, nafcillin, and oxacillin.”
If this device could kill this bug just on the surface, it would be truly awesome. Thanks for the review and information on this device……..Sincerly, OkieFreak

While i think its a good tool for helping keep those items clean and free of bacteria, i’d be alittle worried if this is kept in a family home. More so of little children who happen to mistake it for a “pretty light” and dont know what it will really do. But then again you would hope the parents are responsible enough to not leave it laying out. Good tool tho for those who are very wary of their surroundings, what they tough, what they use.

Wow, that’s just so cool Chirs! It’s a cheap way to kill those germs. It’s a little slow, but hey, It works!

Short wave ultraviolet light is used to kill bacteria in a lot of applications. All applications that I know use interlock mechanisms that prevent any chance of human skin exposure to the direct ultraviolet light source and require exposure times of 20 minutes or more.

A simple wand using this same wavelength of light would give severe skin burns it were doing what it would take to kill bacteria.

Just think in 10 years, disinfectants will be light-sabers that you wave around to kill airborne bacteria while releasing the fresh scent of Death Star mango :D

This looks like an amazing product. It sure will help those germ freaks. It would be nice if Think Geek would give these to schools. And other unsanitary government places.

Spending years working at a water store, filtration is a must. We here use ultra violet lights (UV lights) and they do an excellent job of killing most of the bacteria. So I would say that it does.

I work for an engineering firm that does a lot of HVAC design for hospitals. There are UV lights that can be installed inside different pieces of ventilation equipment that are used to kill more than just bacteria. I forget the specifics, but there’s a specific wavelength that actually breaks down organic material.

These lights are shone on air filter, and other fixtures to help purify the air. They’re also used in swimming pool applications, too.

yes it does… even the act of leaving you shades open at home and letting the sun in can help reduce bacterial count, as well as, fungus.

The sun’s not only there for light.
