Downlighters are recessed light fixtures installed in hollow openings in ceilings. They consist of a trim portion visible from below and a housing installed in the ceiling containing a lamp holder. There are different styles of trims including cone, lens, and wall washer trims. Lamps can be directional, containing reflectors, or diffuse, controlling light distribution omnidirectionally. Downlighters offer advantages like hidden light sources and energy efficiency but have disadvantages like reducing ceiling insulation and fire integrity if not installed properly according to standards.
