A light with integrated light and thermal guides, and having solid state light sources such as LEDs. The light guide includes a material having a first surface and a second surface opposite the first surface and forming an interior volume. The light guide is coupled to the LEDs for receiving and distributing light from them through the first surface, and the light is transported through the light guide until the light is extracted from the first or second surface. The light guide can include alignment features such as fiducials that mate with a base. The thermal guide is contained within the interior volume and integrated with the light guide for providing thermal conduction from the LEDs for cooling the light. The thermal guide can be vented to provide for internal cross flow of air for the cooling.
