A solid state light having a solid state light source such as LEDs, an optical guide, and a thermal guide. The optical guide is coupled to the light source for receiving and distributing light from the light source, and the thermal guide is integrated with the optical guide for providing thermal conduction from the solid state light source and dissipating heat through convection and radiation for cooling the light. The optical guide can be tapered to enhance the efficiency of light distribution. The thermal guide can have an external shell connected with internal fins, and the external shell can have a reflective coating to provide for a back reflector behind the optical guide.
