Sylvania headlight is fashioned for brighter and whiter light. This operates with internal gas pressure which significantly reduces the rate of tungsten evaporation. Its analogous non-halogen incandescent lamp operates the same filament temperature with greater luminance and efficiency. This combined effect of higher pressure and the halogen cycle gives halogen lamp much longer life.
