1. Lamp, in particular signal lamp for watercraft, with a fluorescent lamp operated at above 40 kilohertz and with an associated power supply unit, characterised by a U-shaped fluorescent lamp (2) with two mutually parallel limbs (3, 4) and by an operating frequency, at which the radio interference level of the fluorescent lamp (2) becomes a minimum or disappears entirely through mutual superimposition of the interference fields emanating from the U-limbs (3, 4). |
