Seven things consumers need to pay attention to when purchasing energy-saving lamps
Generally pay attention to 7 points:
1. Many consumers purchase energy-saving lamps with reference to the power of tungsten filament bulbs that have always been used. Most manufacturers will list the power of the product itself and the power of the tungsten light bulb with similar luminosity on the package. For example, the package has a "15W → 75W" logo, which generally means that the actual power of the lamp is 15W, claiming to emit a luminosity similar to a 75W tungsten bulb.
2. Some products have energy efficiency labels on the packaging. The product meets the safety specifications, the light is ready to reach a certain level, and the average life expectancy exceeds 8000 hours before the label can be issued.
3, some energy-saving lamps are available in white and yellow light colors. The average person feels that the white light is colder and the yellow light is warmer. To compare the differences between the different colors, you can go to the showroom to appreciate. Users can choose the color of the light that matches the furnishings of the home according to their personal preferences.
4, some stores provide lamp holders to test the lamp for consumers, try it before payment to ensure that its operation is normal.
5, (non-civil energy-saving lamps) When purchasing energy-saving lamps, we must also consider the technical parameters of the electronic ballast, such as harmonic content, power factor, whether or not equipped with filter components and other indicators. Especially in some large-area, high-volume use of energy-saving lamps, we must use low-harmonic, high-power factor, energy-saving lamps with filter components, and install as many power switches as possible to avoid simultaneous switching of large number of energy-saving lamps. The high voltage pulse of the power grid impacts and causes damage.
6, the plastic shell of the whole lamp, should choose high temperature resistant flame retardant plastic shell.
7. Pay attention to the phenomenon that the lamp is affected by normal lighting after the lamp is energized due to the uneven thickness of the phosphor coating.
