A thermally conductive polymer luminaire includes a polymer housing including at least one thermally conductive filler to configure the polymer housing as a thermally conductive polymer housing. The housing includes an inner surface, an outer surface, and a thickness extending between the inner surface and outer surface. The thickness varies along a length of the housing. An electrical component is mounted to the inner surface of the housing opposite a location of the housing having a reduced thickness to facilitate thermal energy release from the housing. A light source is mounted to the housing and electrically connected to the electrical component for emitting light from the housing.

A downlight apparatus includes a light source, a driver, a light holder, a metal rim and two elastic arms. The driver converts an external power to a driving current to be used by the light source. The light holder stores the light source in an holder space of the light holder. The light holder is placed inside a cavity of a ceiling. The metal rim is connected to a bottom side of the light holder. The two elastic arms are attached to one of the metal rim and the light holder for elastically pressing the metal rim to engage an cavity edge of the cavity of the ceiling for concealing the cavity and preventing an accidental fire to escape from the cavity of the ceiling to outside of the cavity of the ceiling.

A fire rated lighting housing (can) has: (a) a bottom that is open; (b) a top that is at least mostly closed or entirely closed; (c) a sidewall that runs from the bottom to the top; and (d) a fire-retarding material that is physically touching at least some portion of the sidewall when the sidewall is in a cool-state. The cool-state is when a temperature of the housing is at or below a predetermined normal operating temperature for the housing. This fire rated lighting housing, with the fire-retarding material, is configured to slow a fire from a lower floor reaching an above located adjacent floor with a minimum predetermined fire rating, which may be at least one (1) hour or more. Additionally, the top and the sidewall at least mostly enclose an internal-volume that is configured to directly house a light emitting element, like a LED (light emitting diode).
