Abstract
A ceramic metal halide lamp according to various embodiments can include a discharge vessel and an ionizable fill. The ionizable fill is sealed within the discharge vessel. The ionizable fill includes an oxygen dispenser to introduce oxygen in a form of a pellet into the discharge vessel in a controlled manner to facilitate a tungsten halogen wall cleaning cycle. The pellet comprises aluminum-oxide and molybdenum-oxide.
