I bought the SWISSINNO 9W for a 30 sqm large room and used only at night when it is dark. It was good to see from every angle. Of the estimated 25 houseflies were early in the morning, only only 2-3 "in the pot" and at least one of them was still alive. This went on for about 10 days until we left the windows open at night because of the heat. The next morning, there were many small insects in it which have littered the electric wires. The I get back but also with a normal table lamp, just as I sweep the insects then simply off the table ... The purpose of it was to eliminate those pesky house flies, which is not really succeeded.
