Energy-saving lamp purchase note seven things
1, many consumers buy energy-saving lamps are used as a reference tungsten light bulb power. Most manufacturers will list on the packaging the power of the product itself and the contrast of the tungsten filament lamp power. For example, a "15W → 75W" mark on the package indicates that the actual power of the lamp is 15W, which is claimed to emit a luminosity similar to a 75W tungsten bulb.
2. Some products have energy efficiency labels on their packaging. The product meets the safety standards, the light preparation reaches a certain level, and the average life span exceeds 8000 hours before the label can be issued.
3. Some energy-saving lamp models are available in white and yellow light colors. Most people think that the white light is colder and the yellow light is warmer.

4, some stores provide lampholders to consumers to test the lamp, try before payment to ensure its normal operation.
5, (non-civil energy-saving lamps) In the purchase of energy-saving lamps, but also consider the electronic ballast technical parameters, such as harmonic content, power factor, whether installed with filter components and other indicators. Especially in the case of large-area, large-volume use of energy-saving lamps, we must use low-harmonic, high-power factor, energy-saving lamps with filter parts, and try to install as many power switches as possible to avoid switching off the large number of energy-saving lamps at the same time. The high-voltage pulse of the power grid causes damage.
6, the plastic shell of the whole lamp, should choose the heat-resistant flame-retardant plastic shell.
7. Observe whether or not the phenomenon of normal illumination of the light due to the uneven thickness of the phosphor coating is observed after the lamp is powered on.
