The beams of grid spotlights and spotlights (ceiling lamps) are relatively concentrated, and the light-emitting directions are consistent, so they belong to functional accent lighting lamps. The application occasions of these two types of lamps are similar, and the difference is more about the choice of styles and installation methods. These two spotlights are widely used in hotels, shops, venues, clubs, restaurants, supermarkets, villas and hardcover rooms and other key areas where indoor space needs lighting rendering. Nowadays, LED spotlights are more and more favored by consumers, and most of them use high-efficiency and energy-saving LED lamps, which have better light efficiency and energy-saving performance than traditional fluorescent lamps. At present, the domestic brands are Sidon, NVC, Opal, WAC lighting, Taiteng, Sanxiong Aurora, Qiya lighting, TCL lighting, on-product lighting, Huayi lighting and so on.
