Lots of flying insects (including flies, moths) use the sun to navigate. They judge whether they are flying in a straight line by keeping the sun at the same angle to their direction of flight.
The light bulb confuses their sense of direction (they "think" it's the sun). If, for example, they are following the rule "keep the sun directly to your left", they will fly around the bulb in an anticlockwise circle. If, instead, they are trying to keep the sun at "10 O'Clock", they will spiral in towards the light in ever decreasing circles, until they are whizzing around in as tight and fast a circle as they can manage. If they are trying to keep the light at "8 O'Clock" they will spiral out away from the light.
How long they keep going for without changing course is anyone's guess.
For mathematicians out there, the flight path is a logarithmic or equiangular spiral (see link)

They think its the sun or moon they use for navigation.
