Occasionally, a prospective graduate student for eperimentelle Electrophysics (Specialisation Low Voltage) is sometimes used meaningfully for private missions. I asked my son 2 of this energy-saving lamps for testing purposes. If you want to know, below the measurement results (abridged) in an understandable short form: The lamps have at an ambient temperature from 20.04 to 20.11 ° C and a relative humidity zwichen 45.08 and 45.17% a power consumption of 0.0788 or 0.0807 watts. The projected service life is (at a time stay in the socket) 6.7 to 7.2 years. Frequent removal of an electrical outlet reduces the lifespan. The theoretically calculated end of life is reached when the light output of the lamp drops below 75% of their source output power. The annual electricity cost is (depending on the tariff) from 7.2 to 8.4 cents per lamp is fitted.
The installation of sensors and motion detectors makes absolutely no sense for lamps of this type. The power consumption would increase by 15 to 35 times without a further benefit, the same time the increased production costs would bein influence the sales price adversely.
The light color is natural - as with many things - a matter of personal taste, but at the price .....
