Some people, like me, prefer the small and very bright light from the Fenix L0P. Others prefer the less bright, but long run times of the ARC AAA. Both old or new version. While still others prefer, for reasons I don't understand, the least bright, and least useful Maglite Solitaire. I guess you get what you pay for when you pay $6.50 for a light, instead of the manly 30 - 40 bucks. The Solitaire was fun for it's day. Baby size with babyish light to match. While it is true that ANY light is better than nothing if you are in a pitch black condition, the Solitaire sucks batteries with about 2:40 of life before it dies. Much of that light is below battery half life. It does have a solid frame and is quality built, but the tecnology is virtually useless. In a word, "crap-tacular". I am not against long run times, but I see the ARC more as an emergency light if I ever got trapped in an elevator, or under rubble after an earthquake. Great for those, "I only need a little more light" situations, but maybe not powerful enough to ward off monsters from the dark. I know many of you guys love it, but it looks like aligator skin. Not attractive in my eyes. Quite simply, for me, brighter is better. I love the fact the Fenix LOP is visibly brighter than your standard 3 D-cell light, and fits in your pocket. Small, sleek, and bright. It's everything you could love about technology rolled into one light. But it lacks any type of full regulation. But even when dimming it beats the pants off a Solitaire. Want better run times with less dimming? Try a Lithium or NiMH battery. What are your thoughts?
