I was invite to an LED Symposium in Cincinnati, OH present by several Chinese manufactures. I brought my UV Meters. Most of those in attendance were from the Pest Control Industry. They demonstrated a 18" 48 bulb 4Watt LED UV 350(?)NM set up. I was sitting in the third row directly in front of the display. The representative dimmed the room lights, turned on the fly Trap and he release some filth flies within a foot away from the Fly Trap and most of the flies entered the trap and were impaled on the glue boards in the trap. I had both of my UV meters turned on and although I had a small .045 reading on one meter, the other did not detect the UV light.
I was not the only one with a UV meter. No one was impressed. I was given four sample bulbs to try.
When we get a warm night here in Central Kentucky I will set out two traps with the UV LED Light Mount Stick.
I will post the results later this week. I am not holding my breath.
This particular group of LED Manufactures has been pushing the LED Bar concept for some time, and granted, the 48 Bulb Bar produced 359NM of UV at the bulb. Ten feet away, no read at all. There is just not enough surface on the face of the bulb to produce any volume of UV. I told them what I thought. I wish I could read their minds. I bet I am never invited to another one of the demo meetings.

I'm not surprised because the systems built for pest control are specific and dedicated to restricted areas, a few square meters only. If they build something too strong, then the insects from outside could be attracted indoor when doors are open, this is not good. I used these kinds of systems for years when I was quality manager in a big factory, especially in the chocolate factory part. We used two systems, one with UV tubes with an electric system which electrocute the specimens attracted, just at the entry of raw material storage area, and some pheromones traps, dedicated to capture the small food mites (Ephestia, Plodia spp). Both systems used simultaneously were great and the results were perfect, very efficient. Now for our purpose, it could be interesting to know if they could increase the efficiency of their UV tubes, in terms of distance...certainly they can do that...if there's a commercial interest with a lot of demand, they will do it for sure. If not, they won't make any effort in this way. Thierry
