Ordinary consumers don’t know much about the internal technology of desk lamps (mainly including core components-ballasts/adapters, light-emitting components-lamp holders/tubes/LEDs). There is a certain degree of blindness in choosing colors. In fact, just pay attention to the following points when buying:
1. look at the light
The color temperature is reasonable (about 4000K); (2) The brightness is stable and the light is uniform; (3) The light is soft; (4) No flicker; (5) The lampshade is designed reasonably, and there is no glare (the bright spot can be seen by the eyes).
2. Look at the documents and various certificates
Quality inspection reports, product qualification certificates, quality assurance cards, user manuals, other patent certificates, etc., in addition, must have the national security compulsory certification mark CCC, which is often referred to as the "3C" certification mark. These certificates are actually a way for a specialized agency to give consumers a check.
3. Look at the use and after-sales service. The method of use and maintenance should be simple and convenient, and there must be a repair address and telephone number.
4. see if it is easy to replace the lamp
The lamp tube must be replaceable to extend the life of the entire lamp. As LEDs cannot be replaced, it is recommended to choose carefully.
The above four points are very important for purchasing a reading lamp~
