Re:Why flying insects gather at artificial light

There's variants where the light is in a location that is hard for insects to exit. I've seen 1) fan causing airflow that's hard to "fly upstream" in 2) funnel shapes that make entry easy, but finding the exit hard. These avoid the zap aspect, and use less power (LED and maybe fan).
We used to have them in a lab I worked in and occasionally a larger insect (e.g. wasp) would get caught between two rows of the grid and you'd hear it spark / them cook...
