Abstract: A lighting device has a light tube with a cylindrical housing that has a longitudinal axis and encases an electrical circuit including a switch, a rechargeable battery, a secondary induction coil, a receiver circuit, and an elongated light panel. The cylindrical housing includes a ferromagnetic material and an elongated window, and the elongated light panel extends substantially parallel to the longitudinal axis adjacent to the elongated window. The light tube is magnetically held in place by a permanent magnet in a mount and can rotate around a concave surface on the forward side of the mount which has a complementary shape to the cylindrical housing of the light tube. The mount also has a primary induction coil and a transmitter circuit within the interior space of its shell. The mount can rotate on a base, and a power cord operatively engages the transmitter circuit in the mount.

Abstract: A bath water heating device for use in a small water environment, such as a bathtub or the like, that is operable to maintain water in the small water environment at a desired temperature. The device may filter water as it is pumped through the device. Additionally or alternatively, the device may provide ambient relaxation and/or entertainment content to a user, such as a bather or the like. The device may be wirelessly connectable to external input/output devices.
