How can the lamp work at all without a ballast? Could the tube be somehow self-regulating? Note that I have removed the little plastic cover over the connector on the tube (as seen in the picture linked above), and there are no active components inside it there are only leads from the connector to the tube itself. This surprises me because I thought the ballast was critical to fluorescent tube operation, both to regulate the current so as to not blow the tube, and for providing a pulse for striking the arc. The lamp itself is a circular fluorescent tube of this type, and to my surprise I found that, in the armature, there are only two components whatsoever: The power switch and a glow starter, connected in the ordinary way, only there's no ballast. I have a desk lamp which, sometimes when I start it, causes my computer monitor that is connected to the same outlet to turn off and reset, so I disassembled the lamp to see what could cause this to happen.
