Energy saving lamp E 27Energy-saving lamps can save about 80 percent of electricity costs compared to normal bulbs. Light bulbs convert 95 percent of their energy into heat and only 5 percent in light. Energy-saving lamps, on the other hand, transform electricity into five times as much light. In addition, a light bulb lasts only about 1000 hours, ESL, however, 5,000 to 19,000 hours.
Energy-saving lamps are in principle nothing more than folded fluorescent tubes with screw base. These include the energy-saving lamp E 27. It has a 27-pin base and usually a typical pear shape.
The lamps are available in different shapes and with different amounts of watts, starting from 8/9 watts, which corresponds to an incandescent lamp of about 40 watts. The lamp is bought most with
11 watts. Energy-saving lamps with a 27er socket are usually slightly larger than comparable incandescent lamps, especially if they have the spiral shape.
Energy-saving lamps with 27er base are available in discounters, where they are very cheap, as well as in the specialized trade. The cheaper models are not necessarily worse, their life is only lower. The very reasonable price compensates for this defect. Otherwise, the lamps hardly differ. Energy saving lamps with 27er base you get from about 4 euros. In specialized shops they cost around 15 euros.
Energy-saving lamps contain small amounts of mercury. For this reason, they must not be disposed of in normal waste.
They belong to hazardous waste. Dispose of them at the dealer or at municipal collection points.
