In a folded discharge fluorescent lighting device, inter-channel isolation means are provided by proper selection of the length and diameter of a secondary path. The diameter of this path, in particular, is chosen to be small to increase the electrical resistance along this path and to thereby cause the arc discharge to follow the main current pathway. The small diameter promotes rapid recombination of ion pairs, thus acting to increase the resistance of this secondary path. Likewise, in another embodiment of the present invention, a volume between the main channels is filled with an ion recombination enhancement material such as glass fibers or glass wool. The present invention may be configured in the approximate shape of a conventional incandescent lamp or may even take the form or a flat fluorescent panel.
