| 1. A light burner comprising:
a discharge chamber containing a gas sealed in the discharge chamber by a seal;
a pair of electrode shafts, each of which partially intrudes from the seal into the discharge chamber;
a wrapping, at least partially contained in the seal, freely wound around at least one of the electrode shafts; and
a number of containment elements positioned along the longitudinal axis of the electrode, wherein the number of containment
elements are configured to (i) constrain the wrapping in its motion and (ii) allow substantial free movement of the wrapping
to expand over the electrode shaft in both radial and axial directions within the constrained motion.
