Surefire minimus... Awesome headlamp.
Fenix PD35... great flashlight.
Surefire E2D defender..... Awesome flashlight.
I have hundreds, if not thousands of hours under headlamp, using the tikka -TacTikka, and the SF minimus. But the CR123 are provided through work... so .... not the best option unless you want to spend the $$$ on batteries.
for flashlights, the PD35 is very bright, and nice to carry... but the E2D defender is an absolute tank... it is my carry flashlight if I am traveling.
