Arc tube ( ) has a bulbous body ( ) with a hollow center portion ( ) and opposite ends ( ). Each of these ends has a cylindrical terminal-receiving section ( ) extending therefrom. The hollow center portion ( ) has an internal length A and an internal diameter B that provides an aspect ratio of less than 5 and an outer surface area to inner surface area ratio, measured in square units, of less than 1.5. Electrodes ( ) and ( ) are hermetically sealed in the terminal-receiving sections ( ). The lamp uses less than 7 mgs of mercury. The low pressure operation allows the use of the arc tube in lamps without a shroud and the low mercury allow the lamp to pass TCLP requirement and be conventionally landfilled.
