简介 A ceramic gas discharge metal halide (CDM) lamp (10) capable of retrofitting into existing high pressure iodide (HPI) metal halide and high pressure mercury vapor (HP) lamp fixtures for significient energy savings, the CDM lamp (10) having a ceramic discharge vessel (12) containing a pair of discharge electrodes (17, 18), a Penning mixture of the rare gases neon and argon, and a chemical fill which includes an oxygen dispenser and which restricts strong oxygen binders to 5 mole percent or less. In a preferred embodiment, the discharge vessel (12) has an aspect ratio R of less than 2, a wall thickness t of up to 1.2 mm, a spacing d between the discharge electrodes (17, 18) of up to 14 mm, and a passive antenna (26) on the outer wall of the discharge vessel (12), with the shortest distance a between a discharge electrode (17, 18) and the floating antenna (26) of up to 7 mm.
