Proper placement of a lighted area produced by light from a light emitting diode chip relative to a base provides for a lamp for use with conventional flashlights having a collimating reflector. At least a portion of the light produced by the light emitting diode chip then is collimated into a beam of light for projection from the flashlight. Various means are disclosed to provide for a radial distribution of the produced light wherein the produced light properly strikes the collimating reflector for concentration into the beam of light. Lens elements, scarification of an exterior surface and placement of reflective surfaces are all disclosed as examples of methods to provide for the desired distribution of light. Such methods may be used singularly or in various combinations.
