This kind of recessed light fixture embedded in the ceiling, all light is projected downwards and belongs to direct light distribution. Different reflectors, lenses, shutters, bulbs can be used to achieve different light effects. The downlight does not take up space and can increase the soft atmosphere of the space.

The main problem of downlights is on the lamp sockets. The exits of some miscellaneous downlights are not resistant to high temperatures and are prone to deformation, causing the bulbs to fail to be screwed down. Now, all lamps can be sold only after passing the 3C certification. Consumers must choose 3C-certified downlights.
