A device for illuminating a space comprising is discussed. In one variation, the device includes: a central body portion, with a length and a width, and including two plates running along the length of the central body portion wherein the two plates are separated by a spacer; an opening for the removal of heat during operation of the device that extends along a portion of the length of the central body portion, a light emitting diode on the central body portion; a reflector, extending from the central body portion, for reflecting light emitted by the light emitting diode towards the illuminated space. Other variations are also discussed as are methods for using suitable variations for retrofitting existing non-light emitting diode light sources.
