Wire-Ended & Bi-Pin
Filament lamps will perform to specification and give optimum life when:,a) They are powered at the rated voltage from a stabilised 50Hz ac supply,b) Ambient temperature is in the range 20 to 25°C,c) No mechanical vibration is present.,Deviations from these criteria can have a significant effect on lamp life, particularly with low current filaments (
