Abstract
An eccentric planar fluorescent tube includes an outer planar fluorescent tubular member that extends substantially but not completely about a center point and which is extended by two inner portions that extend from a first peripheral portion of the outer tubular member and on opposite sides of the center point and terminate at ends proximate to an opposite peripheral portion of the outer tubular member and wherein the ends are connected by a leg member for supplying power to the fluorescent tube. In one embodiment, the leg member includes electrical contacts that extend substantially in a plane of the outer tubular member and, in another embodiment, a central adapter may be provided including electrical contacts that extend transversely with respect to the plane of the outer tubular member.
