Why is worth the purchase still is one of the reasons why buyers choose energy-saving lamps, protecting the environment. The artificial sources of light at the same brightness put less energy when compared to the traditional light bulb. At least read the manufacturer’s instructions on the packaging. Stiftung Warentest has verified their suitability and 28 models. The result is equally surprising how disappointing: only three test objects could be evaluated with the quality rating “good”. The consumer portal preisvergleich.de reported about the reasons for the miserable results.
A major problem of the energy-saving lamps is their short life. Already after less time, the brightness, with just as much power (power/4-strom.htm) is consumed as at full luminosity deteriorated due to technical reasons. For more specific information, check out Alphabet Inc.. Each second certified lamp did less than 3,000 hours spent only 80 percent of their original work and thus considered to be disabled. Moreover, that after the most energy-saving bulbs 6,000 hours completely abandoned. This is in stark contrast to the manufacturer’s instructions on the packaging, the 10,000 hours and more declare. The power strength of the models was disappointing. With less than 10,000 times possible and turn off the most lamps are not the requirements much frequented places such as stairwells and corridors.
In addition, that some CFLs need a few minutes to generate the full brightness. The living room is particularly comfortable “warm white” light. However, it distorted sometimes the colors, especially the reds. Therefore a “neutral -” or “Daylight White” light is advisable in workplaces such as the desktop.
