A supporting member is disposed within the interior of the housing, and supports a plurality of LEDs. A light guide made from a light transmissive material is distally disposed in relation to the LED supporting member for transmitting light emitted by the plurality of LEDs through the distal end of the housing. In at least one version, at least one end of the light guide can be provided with a patterned surface that is configured to produce a uniform illumination spot.
