Stiftung Warentest has once again cast light on LEDs, ESL (also known as compact fluorescent lamps or energy saving lamps) and halogen lamps (colloquially also incandescent lamps) in May 2013. Overall, the LEDs in the test section are the best-and Grünspar shows why this is so!
In the search for the optimal replacement for the 60 watt incandescent bulbs, the Stiftung Warentest has issued a total of 20 pear-shaped lamps placed side by side and checked. In detail, 2 incandescent lamps, 9 LEDs and 9 compact fluorescent lamps were tested. The quality assessment was assessed by means of the categories technical data, environmental/health, declaration and durability.
The LED-The Star Among The Current Illuminants
The result is, as I said, particularly positive for the LED lamps failed. In relation to the incandescent lamp, the LED saves up to 90 percent of energy, produces less heat at the same brightness, does not contain any toxic substances and can also thump with a significantly higher life cycle. The calculated lifetime of the LEDs was calculated to about 50,000 hours. With an LED, you can definitely get quality into the house, which then pays off in the medium to long term also economically correct. The cost of an LED is between € 20 and € 52.
Apart from the LG Electronics A19, all the LEDs tested with the quality judgment “good” cut off. The LG Electronics was criticized by the test persons of Stiftung Warentest because it caused a low hum, which considerably limits the application possibilities of this LED. The Osram Parathom Classic A 60 Advanced, on the other hand, has routed the test with the quality judgment of 1.6 and is among the LED lamps of the superstar, followed, among others, by the Philips LED lamp A60 warmwhite and the Ledon A65 10 Watt. In particular, the LED test values show that these outstanding results in the categories durability and lighting characteristics show. According to Stiftung Warentest, the light of the Ledon-LED even reaches the natural incandescent light. Follow our link if you also ask yourself the following question: Why use LED lamps?
The Energy Saving Lamp-An Alternative In The Short Term
Compact fluorescent lamps or energy saving lamps can certainly be used as an alternative to the LEDs, since they are naturally cheaper in the short term.Compared to the LEDs, they give only a mediocre light. Also with regard to their shorter life, they were rated worse than the LED-lamp competition. The ESLs have a lifetime of approximately 10,000 operating hours. Among the compact light bulbs compared, the Müller Light Ultra Vollcover with the test section 2.1 is in the front area. Right behind this, the Megaman Compact Classic ESL ranks with a test result of 2.2. The Hellweg/Flectorsparleuchtmittel “Klassik” is rated the worst with a poor result.
If you are concerned about liquid mercury, then the energy saving lamps with the mercury alloy may help. Such compact fluorescent lamps, such as theEcobulb energy saving lamp E27 15W, instead of mercury usually contain amalgam and thus make the discharge of liquid mercury extremely impossible.
Here you can also find further facts and savings potentials to energy saving lamps.
The Light Bulb-Quite Old School
The halogen incandescent lamp Stiftung Warentest is the loser among the tested illuminants. Mainly, it is worst in terms of its lavish energy consumption and short-lived durability. Finally, the enormous energy consumption makes the good light of the halogen incandescent lamp extremely fade.
The tested halogen lamps cut in the categories of environment / health, declaration and durability even with sufficient or even deficient. In total, the two tested halogen lamps were awarded the quality criteria 4.5 and 4.8. Despite the special lighting characteristics, the halogen lamp rightly ranks in the last place.
Of course, there are advantages and disadvantages to be found everywhere – on the whole, the overall judgment and the LED bulbs have passed the test of dealledlights with flying colors. These are rightly the front ranks, because they do not contain any toxins, give less heat to their surroundings, have no turn-on delay and are characterized by a superior service life.
The Life Cycle Assessment-A New Way Of Looking
Looking at sustainability, the new category Environment and Health has taken an important place under the motto “Life Cycle Assessment” at Stiftung Warentest. We assess this measure as a positive sign by Günspar, because we also believe that the resources should be handled carefully and responsibly.The life cycle is the focus of life cycle assessment. The lifecycle covers all essential processes, from the procurement of raw materials to production, delivery, application and disposal of the respective light source. Furthermore, this category also influences the impact on health and our ecosystems.
