I'm not sure why you think unregulated is a positive trait. Yes, you might have "usable light for days and days", but you'll find that light level steadily decreasing from day one as opposed to a properly regulated light that will give you a consistent brightness for a long period of time and then gradually decrease the brightness in discrete steps as the batteries deplete until the power source is exhausted.Led Lenser P7. . . Because it is not "Regulated" it will have usable light for days and days.
Welcome to CPF, zbad
I expect you'll get quite a few replies saying "ONE light is not enough!" LOL
I'd have to go with the Surefire E1L.
