The Beijing Municipal Bureau of Quality Supervision recently released the results of spot checks on Beijing-based lamps. Among the 16 types of lighting products produced by 16 companies in the city, 5 were unqualified, and the pass rate was only 69%.
According to industry insiders, whether they like beautiful lighting effects or natural marble lighting, the first thing consumers should consider is safety. The safety performance of the luminaire is mainly reflected in its external entrance and exit and internal structure.
The main quality problems of unqualified luminaires are often inconsistent with the standard structure. Externally, the metal tube entrance and exit of the luminaire wire should have no sharp edges. Otherwise, the sharp edge cuts the wire so that the metal piece is charged, and the table lamp or the floor lamp should have the wire holder. For the interior of the luminaire, the internal wiring of the high quality luminaire is tighter. In addition, the related accessories are of good material, which not only directly affects the service life of the lamp, but also is more environmentally friendly.
