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.
