I found the Pelican L4 when I was looking for a penlight to replace all the previous ones that failed me or just left me wanting. I am a physician now and have had the L4 since I was a medical student. Many times each day it provides a great light source for examing patients' eyes and mouths, and thanks to the LED bulb I have no worries about it lasting as long as I need it. It fits perfectly in my white coat or shirt pocket, but when I do take it out my fellow clinicians always ask about it. I have been so pleased with it that I have given several as gifts to colleagues, and in addition to my stethoscope it is one of the few things I make sure is in my bag when I go on humanitarian medical missions to Africa.
Pros: Intensity of light, durability, longevity of LED bulb
Cons: None to speak of
