I wouldent say a 1,4 amp xm-l is a waste. One of my favorite drop in moudules feeds only 1,5 amp to a warm xm-l. The edc+ x60-l. I would say it reaches about 100 yards max when im up on the mountians with no ambient light. I rarly use it on it's max mode with 1,5 amps. I dont like to use a face melting light up on the mountians, and 1,5 amps is plenty (more than i need). Nice to have a "no-noncene" light that wont suck that battery dry in a hurry, wont heat up. Put a 18650 in it and i know it will last the whole trip.. and still gives more light than i really need.
