A transgenic animal model that is suitable for the cell or tissue specific assessing of thyroid hormone (TH) action in vivo is described. The recombinant DNA construct and methods suitable to generate such an animal are also provided. The assessment of TH action is based on a reporter that is dependent on an endogenously expressed thyroid hormone receptor (TR) and coregulators of said receptor.

A compact fluorescent lamp (CFL) ballast driver includes first, second and neutral AC voltage terminals, a full wave rectifier between the first AC voltage terminal and the neutral AC input terminal, and a separate branch between the second AC voltage terminal and the neutral AC input terminal. A resonator circuit includes at least two inductors and provides its output voltage to a CFL lamp. The driver includes a first state detector circuit to monitor the first AC voltage terminal, and a second state detector circuit to monitor the second AC voltage terminal. The first and second state detector circuits activate respective first and second switches. The first switch shunts one inductor of the resonator circuit, and the second switch shunts another inductor of the resonator circuit. The driver can be housed in a CFL having a capper, a three-way lamp base adjacent to the capper and an arc tube.

A discharge lamp having an improved run-up time is disclosed. In an embodiment, the discharge lamp includes a light-transmissive discharge tube extending from a first end to a second end and having an inner surface and an outer surface, a phosphor coating layered onto the inner surface of the discharge tube, and a fill gas composition capable of sustaining a discharge sealed within the discharge tube. Also included is a resistive heating wire positioned about the outer surface of the discharge tube. In some embodiments, a lamp driver circuit is included that operates when the lamp is turned ON to provide power to electrodes in the discharge tube and to provide power to the resistive heating wire, and operates to disconnect power from the resistive heating wire when the discharge lamp achieves a predetermined percentage of its stabilized lumen output.
