I use a pair of Icon Rogue2 flashlights. claims 100lumen each, but are definetly brighter than the coleman max's that I used to use(115?).
uses 2AA each, and are voltage regulated* so they stay at full brightness as opposed to getting progressively dimmer over time. approx 3hours runtime, so I swap batteries with the set in my charger twice a week. about 35$ each at Fry's Electronics

*best feature ever, when shopping make sure your light does this.
