sorridsky,
the more expensiv flashlights often are built better or offer better performance. When you use them a lot, they are often a bit cheaper then the less expensiv ones (at least in the long run). I´m a Maglite fan because they are really robust. Mine took a lot of punishment and still work perfectly (one fell down a 14 ft. ladder hitting every step on it´s way down without any damage). When you really use the light very frequently buy LED light with a decent quality. Choose one that uses batteries you´re using in other devices (I went for the AA because they´re cheap, easily available and you can get rechargeables with decent capacity. The lights for those cells are usually small enough for EDC.).
The surefire is real pocket search light. The cost per hour of light is horrendous. IMO it´s too bright and expensiv for normal use.
