Hello; Been thinking about the problem of duration in the light with a UV sanitizer. I came up with one idea. Place the light in the space with the largest volume. Th e air will slow down some when it moves into a larger volume. In my house there is a large cavity behind the air filter. Air movement will be slower than in the other ducts which are much smaller.
Another potential way to deal with duration under the sanitizing light might be to install a duct fan into a small duct. I have seen them for six inch ducts. I have considered putting one in the six inch duct that exits just behind my wood stove. That small fan would pull air much slower than the main blower. That small fan could be run manually with a simple on/off switch. On a timer to run some number of hours a day. Even on all the time. Which ever way the air would both be slow and the constant exchange of the air would give many passes by the light(s) every 24 hours. I have no idea of the overall cost for such a setup.
Hello; I guess this may be what I call the inverse square rule. The space I am thinking of is about the size of a dorm fridge. I did read how in some hospital rooms an upper area rig was used. Had barriers to protect the eyes. I guess the idea is to help.Light intensity falls off with the square of the distance so, unfortunately, strong UV light is only strong for a short distance (unless you have a lamp as powerful as the sun.)
