ABSTRACT:
A new light device is disclosed which, in one aspect, has clear housing in which one or more tubular bulbs is positioned which has sockets and/or bulb mounts at each end, one or both of which prevent rotation of the tubular bulb in the housing. Fittings encapsulate each bulb end and socket/mount combination. In one aspect, a torque isolation member is used with a first top fitting. The top fitting is mated with a second top fitting so that the bulb(s) are clamped, held, and stabilized within the housing and so that such rotation does not result in rotation of the bulb(s) within the housing. In one embodiment a fluorescent bulb (or bulbs) is used and a ballast is interconnected with electrical conductors leading to the bulb. In one aspect the ballast is within the housing and in another aspect a battery is also within the housing. In one aspect the housing and related fittings are sealed so that the bulb(s) is within a water-tight enclosure. In certain embodiments bulb sockets are irregularly shaped and are received in irregularly shaped recesses in bottom bulb mounts so that only one correct orientation of the socket(s) with respect to the recess(es) is possible, thus serving as a guide for correct bulb positioning and as an indicator of correct bulb placement and orientation. In one aspect a bulb, a socket, and associated wiring are combined to form an easily removable and replaceable unit.
