Abstract: Fluorescent lamps, along with their methods of manufacture and use, are provided. The fluorescent lamp can include a discharge tube extending from a first end to a second end; a resistive transparent coating (e.g., a tin oxide thin film layer, such as a fluor-doped tin oxide thin film layer) on the outer surface of the discharge tube; and a pair of electric terminals positioned on the discharge tube such that a first terminal is on the first end and a second terminal is on the second end.

Abstract: 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.

Abstract: A colored fluorescent lamp is provided. The lamp comprises an envelope having an inner surface, means for providing discharge within the envelope, a discharge gas fill inside the envelope, a phosphor coating adjacent to the inner surface of the envelope, and at least a barrier coating between the inner surface of the envelope and the phosphor coating. The barrier coating comprises a blend of alumina and at least one coloring pigment.
