How long is the warranty period of lamps stipulated by the state?

There is no relevant provision in the national standard about the warranty period of lamps; The after-sales period promised by the manufacturer shall prevail. General lighting appliances and light sources are guaranteed for one year, and lamps can be guaranteed for two years.

different from the "three guarantees" commitment of household appliances, the state does not clearly stipulate the warranty period for lamps, only depending on whether the manufacturer has relevant regulations when leaving the factory. If the merchant does not explicitly inform that the warranty is not granted at the time of purchase, the consumer can apply for rights protection.

Extended information:

1. In electrical engineering, the light bulb itself has a life span, and the life span of incandescent lamp is 1 hours.

2. If the lamp is illuminated continuously for 24 hours every day, the whole life of the lamp is about 42 days.

3. The warranty period of the light bulb you mentioned is understood as the warranty period after the project is completed and accepted and handed over to the construction unit.

4. Because of the particularity of the project, it is generally agreed in the contract that the warranty period of electrical engineering is 2 years, but the light bulb is consumable and cannot be equated with the warranty of circuits and switches. Personally, as long as the light bulb is in good condition at the time of handover, it should be directly noted on the handover list. If the incandescent lamp is in good condition and has problems, it will be directly replaced by the construction unit.

judging from the relatively popular lamps on the market at present, there are mainly LED downlights and LED ceiling lamps. According to the survey, the warranty period of indoor LED lamps is 2-3 years, accounting for 82.2%, that of six months to one year accounts for 1%, and that of more than five years accounts for 7.8%. < P > Among them, a brand of 3*1W LED downlight is called lifetime warranty, and the price of this lamp is only sold in 27 yuan, which makes people suspicious. I wonder how this manufacturer can fulfill his promise.
