Ships Same Day
Two D-cell LED bulb. This LED bulb is for Fulton military spec flashlights (MX-991/U and MX-993/U), as well as other Fulton flashlights that utilize a PR6 bulb.
The PR-LED bulb should not be used in flashlights that use 3 D-cells. Using more than 2 D-cells will cause the LED to burn out prematurely.
