Nowadays, ceiling lamps and lanterns are increasingly becoming the new favorite of people's homes. Consumers should consider several aspects when choosing: 1. In large stores, choose products with "Three Guarantees" commitment and lamps with CCC certification mark. 2. It depends on whether the product identification is complete. Regular products should be identified: trademark and factory name, product model and specification, rated voltage, rated frequency and rated power. 3. Check whether the power line of the lamp has CCC safety certification mark. 4. Look at the lamps

nowadays, ceiling lamps are increasingly becoming the new favorite of people's homes. Consumers should consider several aspects when choosing:

1. In large stores, choose products with "Three Guarantees" commitment and lamps with CCC certification mark

2. It depends on whether the product identification is complete. Regular products should be identified: trademark and factory name, product model and specification, rated voltage, rated frequency and rated power

3. Check whether the power line of the lamp has CCC safety certification mark

4. Check whether the electrified body of the lamp is exposed. After the light source is installed into the lamp holder, fingers should not touch the electrified metal lamp cap

5. The anti electric shock protection types of ceiling lamps can be divided into 0, I, II and III

0 lamps have poor safety. They rely on basic insulation as protection against electric shock. In case of basic insulation failure, it is easy to produce electric shock hazard

the anti electric shock protection of class I lamps not only depends on the basic insulation, but also includes additional safety measures, that is, connect the accessible conductive parts to the grounding protection conductor, so that the accessible conductive parts will not be electrified when the basic insulation fails. There is a grounding symbol next to the grounding terminal of class I lamps. It should be noted that the metal shell of class I lamps should be effectively grounded. If the lamp replacement tube can touch the ballast, The ballast shall also be effectively grounded

the anti electric shock protection of class II lamps not only depends on the basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation. In case of failure of the basic insulation, it can also rely on the protection of supplementary insulation

the anti electric shock protection of class III lamps depends on the power supply for the safety extra low voltage, and the voltage higher than the safety extra low voltage will not be generated inside the lamps

therefore, class I, class II and class III lamps should be selected as much as possible
