Like all traditional maglites
Note: this is not the led version of the light. however, the led version will cost you a lot more. also, this light, like all traditional maglites, comes with an extra replacement bulb in the tail of the light. as someone who has been using mag-lights for over 20 years, i can tell you that there are few, if any, flashlight manufacturers who have stood the test of time like maglite.
