1. When I was growing up, my dad had a MagCharger. He had mounted it to the frame of his bed, and I remember thinking it was badass to have a light/weapon at your bedside. Recently asked him about this light, and not only does he still have it but he also has 2 repair receipts from the late 1980's.
2. When I was a kid, a Camo AA Maglite. I had a couple of other Maglites, but the Camo AA was just so freakin cool.
3. When I was a teenager, the Photon Freedom. Especially the covert amber (literally it's 20 years later and I've got an amber HDS on order to scratch this very itch!!). I remember reading about the different colors and uses, and always really wanting a cyan one. I've still got my 20 year old Photon with the small on/off slider. It's white and unshrouded. My dad still has a blue, green, and THE covert amber from back then. He keeps the batteries fresh and they all still work.
4. When I was doing sheet metal work, the Surefire Maximus. Have put 1000's of hours into a couple Maxiumus. Absolutely love them. The Maximus is my most influential light. The 1-500lm dial is so useful in a shop setting. 1-100lm is enough when working up close with reflective surfaces, and 500 is more than enough when doing anything else. I don't do sheet metal work anymore, but I still use a Maximus almost daily.
5. When I was working on a ranch, the Fenix TK75, 2600lm model. Approaching 10 years with this light. Was used for bumps in the night when working alone for extended stints. Has had quite a bit of use "ceiling bouncing" in greenhouses, garages, etc. to allow hands free work. Also have had 2 "tactical" situations where this light has blinded and disoriented a potential perp. I've kept this light handy for most of the last 10 years, and now it resides on my nightstand, fulfilling the same duties that my dad's MagCharger did almost 35 years ago,
