T16X35 15S 24V,10W

Electric bulb is a light emitter that utilizes a reflective temperature formed by the current flowing through the filament. Filament is a coil type of tungsten lines. An inactive gas(i.e. alcohol) is injected into the bulb made of glass. Such gas injection bulb has general characteristics as follows 1) When the used voltage of the electric bulb is lowered by 10% than the rated voltage, the life span of the bulb extends by four times and consumption power goes down to 85% while luminosity(brightness) decreases by about 30%. 2) When the used voltage of the electric bulb goes up by 10%, the life span of the bulb sharply decreases to 30% and consumption power increases by 10% while brightness enhances by about 40%. The standard life of an ordinary electric bulb is 1,000 to 1,500 hours.
