this unit.
The other is a square house unit rated at 4watts with 2 bulbs and 254nm.
They essentially are the same...correct? Except for strength.
If this is so, Can I top mount the square unit to a box with a window and sterilize my stuff before working to reduce contaminates?

Check this out. Aparently 254nm is the frequency used in killing organisms. Maybe use the light as a prefilter for a laminar flow hood.

we know that UV & sunlight are effective,
the link above extolls the virtues of red light
in killing molds.

Siam, would it be possible to post a picture of your uv glovebox?

So...it not effecting fungii....Would I be able to use this light to clean up samples/specimens? If i have a petri that starts to germinate and expose it to the light will it kill off competing bacteria and viruses?

the primary limit would seem to be penetration,
opaque substances might shield bacteria from the germicidal light.

Or...still air and uncover...expose...cover....
I'm going to try this out...see how it works. I'll post any experiments i may have. Maybe make a petri up of some mea...and put a fingerprint in the middle....let my germy print germinate...then expose it. On another dish, put some spores with no exposure to my finger...and another with spores and a print. Expose them all and see what happens....like i said...i'll post if i try this.

They appear to range in price from 70bux and up up and way up.
I was thinking maybe people could use this on work areas for sterility, needle tips before injections, heck, why not even agar after its cooked.
What about a casing that has a corner of trich, could be possible to zap the area and kill everything there, the food source that exists there if any at all would still be usable. And if not, at least the infection wouldnt spread.
just some thoughts.

Seems to me that a handheld would increase the risk of exposure to the UV, which can cause cataracts or blindness if it hits your eyes and increases skin cancer risk. People who want to get into using UV should make sure they do some research and understand its proper use, as it is a powerful technology with some potential hazards.

Is a flame not both easier to use and more effective.I was thinking maybe people could use this on work areas for sterility, needle tips before injections,

no heat
no flame
just hold over area and its sterile in 15 seconds
no chance of fire.
is it more cost effective than a lighter
nope
but is it possible that it has its uses, maybe. figured id make a thread and try to see what others thought. :)
