1. Energy-saving lamps and led lamps have different working principles. Energy-saving lamps are electronic luminescence generated by heating tungsten wires, and led lamps are made of led beads connected in series, which are luminous bodies that convert AC 200 V power supply into voltage through light-emitting diodes.

2. In terms of brightness, the brightness of led lamps is much higher than that of energy-saving lamps, and the power is also greater than that of energy-saving lamps.

3. Under the same luminous flux, the consumption of led lamps is only 1/4 of that of energy-saving lamps. It can be said that the energy consumption of led lamps is very low, and better energy-saving effect can be achieved.

4. The service life of 4.led lamps and energy-saving lamps is different. The normal service life of led lamps can reach over 50,000 to 65,438+10,000 hours, while the normal service life of energy-saving lamps is only about 5,000 hours. Comparatively speaking, the advantages of led lamps will be more obvious and the cost performance will be higher.

5. Compared with environmental performance, the advantages of led lamps will be more obvious. Led lamps have no harmful substances, and the materials used are also very safe and environmentally friendly. There are harmful substances such as mercury in energy-saving lamps, which will easily cause environmental pollution once discharged into the air.

6. The difference between the two can also be seen from the price. The market price of ordinary led lamps is much more expensive than that of energy-saving lamps. For ordinary consumers, it is very likely that they will choose products with lower prices to buy.

What are the precautions for buying energy-saving lamps?

1, many consumers will refer to the power of tungsten filament bulbs when purchasing energy-saving lamps. Most manufacturers will list the power and contrast luminosity of their products on the packaging, which is the power of tungsten filament bulbs. For example, there is a sign "20W→85W" on the package, which generally means that the actual power of the lamp is 20W.

2. Energy-saving lamps on the market have two colors to choose from: white light and yellow light, but most people think that white light is cold and yellow light is relatively warm, so they can choose according to their own preferences and needs. Of course, the color of lamps and lanterns should match the overall style of home, in order to have better decorative effect.

3. When purchasing energy-saving lamps, we should also consider the technical parameters of electronic ballasts, such as harmonic content, power factor, whether to install filters, etc. Especially in some large-scale and large-scale occasions where energy-saving lamps are used, we must choose energy-saving lamps and filter elements with low harmonics and high power factor, and install as many power switches as possible to avoid the damage caused by high-voltage pulse impact of power grid caused by the simultaneous switching of a large number of energy-saving lamps.

Most stores will provide lamp holders for consumers to test. When choosing lamps and lanterns, you can try them first to ensure their normal work and observe their brightness. Pay attention to whether the uneven thickness of phosphor coating affects the normal light emission of the lamp after it is electrified.
