Richard from Manhattan, Kansas writes
It was advertised as new with an open box. I have set it up and the flies do not seem to have much interest. Is there a way to test the amount of UV being produced by the bulbs?
New Vector Plasma lights would come from the manufacturer with brand new bulbs. It is generally recommended to replace bulbs annually in the Spring for the best control of flying insects. (The UV strength will decrease greatly before the light actually burns out.)
