An incandescent lamp may be formed from a shell having an exterior side and an interior side defining a cavity, and with an internal wall defining a through passage extending from the exterior side to the interior side. A light source is located in the cavity facing the interior side, and coupled to electric lamp leads extending through the passage. A heat radiator assembly is adjacent the exterior side, and includes heat-dissipating surfaces exposed to air. An integral power supply is enclosed in the heat radiator assembly and electrically connected to the light source through the electric lamp leads. A threaded base having exterior electrical contact points is electrically connected through base leads to the integral power supply. The shell, radiator assembly and base are mechanically coupled as a unit. A lens may cover the shell to enclose the cavity and light source.
