Been a member at CPF for a while and trying to answer the same questions about what lights. The answer for me is different lights for different purposes.
My everday carry light is a Digilight T-9, a "Surefirelike" light, but about three times brighter than my Surefire G2, and about 30 percent longer. Still small enough to fit in a pocket of my jacket without noticing it. They're about 50 bucks from

For longer run times I have several of the Nuwai 1-watt Luxeons that run off a pair of rechargeable NiMH AA batteries, and some of their 1/2 watts that are tiny and run off a pair of AAA's. A google search for Nuwai flashlights will turn up a ton of resources. They're well-made little lights, machined aluminum, O-ring sealed, DC-DC converters which greatly extends the run time and brightness, even in the $10 1/2 watt modes. The 1-watt models are about $20.
For when I need to reach out and touch someone, I built 3 of the "Roar of the Pelican" lights, the 4-D, 2-D and 2-C. They run off different battery solutions and have different run times, but they are incredibly bright. My T-9 is about 3 times as bright as the Surefire G-2, the ROP lights are 3-4 times as bright as the T-9. I can easily light up someone at my back property line, about 600-700 feet from the house with one of these. This is a fairly simple mod, the 4-D is incredibly simple, just replace the batteries with 6 sub-C NiMH batteries, replace the bulb, lens and reflector, and you'll have an 800 lumen light for about $100 that is rechargeable and runs for an hour.
