I've done a little reading this morning about UV sanitizing. I'm reading that 250nm to 280nm range is very good for killing bacteria, mold and other things, and also 405nm, as there is a company (or more) making lighting in that range. I bring this up as a lot of us may have UV sources already (we have a Saati 450 ProLite) and I'm wondering if we can possibly use this to disinfect areas of the shop, bathrooms, kitchen etc. I built a 200w 405nm exposure lamp around the time we bought the Pro-Lite, as a hobby project, and it's small enough to carry around to do people's keyboards, desks etc., as well as just putting it in a rest room and leaving it on for a minute or two facing a wall (the inverse square law applies here) would be helpful. I see the small hand held units at 3 watts. Thoughts? There are a lot of good brains here. I would not expose people to it of course, though the 250nm - 280nm range seems to be deadly to the bugs, but not have an effect on human skin or eyes. It's an emerging technology for sure...
