This guy knows his lights. Far too many reviews to read them all but he seems objective and actually shows what the beam patten looks like and battery life is tested first hand.

Spot light I use a Surefire M4 Devastator.
Pocket light I use a Surefire U2.
Headlamp Pelican Duo LED,Xenon.
Trucklight the good old Maglight 4D and a minimag in the glovebox.
