a bottom that is open;
a top that is at least substantially closed or entirely closed;
a sidewall that runs from the bottom to the top; and
at least one fire-retarding material that is physically touching at least some portion of the sidewall when the sidewall is in a cool-state; wherein the cool-state is when a temperature of the housing is at or below a predetermined normal operating temperature for the housing; wherein the at least one fire-retarding material is configured to slow an elevation of the temperature above the predetermined normal operating temperature to achieve a predetermined fire rating for the housing; wherein a thickness of the at least one fire-retarding material is variable along the at least some portion of the sidewall; wherein the at least some portion of the sidewall is an entire exterior of the sidewall; wherein the thickness is thicker towards the top and thinner towards the bottom;
wherein the top and the sidewall at least substantially enclose an internal-volume, wherein the internal-volume is configured to directly house at least one light emitting element.
