An air-cooled light comprising a cylindrical transparent sleeve that shields heat generated by a high intensity discharge lamp from the surrounding environment. The air-cooled light of the present invention comprises an outer cylindrical transparent sleeve that surrounds a high-intensity discharge lamp. Sealingly attached to opposing ends of the transparent cylinder are two end plates for supporting the transparent cylinder from a ceiling structure. O-rings positioned between the end plates and the cylindrical transparent sleeve provides a seal for insulating the interior of the transparent cylinder from the external environment. The high-intensity discharge lamp is supported inside the transparent sleeve by a bracket attached to one of the end plates. Mounted on the interior surface of the transparent sleeve is a thermal protector that disconnects electrical power to the high intensity discharge lamp when the temperature inside the transparent sleeve reaches or exceeds a predetermined maximum safe operating temperature.
