it could be comparable to a "quartz" lamp
it would depend on the soup in the bulb. A tungsten filament was standard fare. Once the lamp envelope is evacuated an inert gas is exchanged for air, this helps the glass stay "clean" by delaying particles of tungsten burning off and depositing on the globe. Quartz is used in all high quality lamp globes, the compactness of the filament, quality of the reflector and associated optics drives the efficiency and lumens produced. Now comparing the Super lit to a HID head light the super lite generates visible lite by heating the filament until it glows. An HID utilizes a plasma arc contained in vacuum, to produce light. think of it as a tig/ mig welding
