What kind of all-copper lamp manufacturer is highly reliable?

As all-copper lamps are more and more loved and accepted by people, there are more and more all-copper lamp manufacturers, but this has also led to uneven quality of all-copper lamp products and ineffective guarantee of service quality, as a result, many people's trust in all-copper lamps has also declined, so what should we do when choosing all-copper lamp manufacturers? 1. Choose a brand with good reputation: As the saying goes, the eyes of the masses are sharp, and only a brand that can stand the test of the masses is really good. 2. Look at brand building: good manufacturers attach great importance to brand building. Good brand manufacturers have strong factories, physical product exhibition halls and the construction and publicity of online official websites. 3. Look at the certificate: no matter what product can't stand the authoritative test, generally, it must have industrial and commercial business license, 3CCC compulsory certification, patent product application, international authoritative certification, etc. 4. Actual engineering decoration cases: only strong manufacturers and professional design teams can take over complex and huge engineering cases, and only through real practical cases can the recognition and professional expression of all-copper lamp manufacturers be reflected.
