Hi i am new here and i want to ask a question about modification. I have a not so good maglite with output about 100 lumens. This flashlight works with 3 C batteries. Now my question is if i can change the led with a better cree led 3.6 v and using CR123A batteries witch is the same size as C batteries (as far as i know). Does this modification can be done easely or will i have to do more things to work
