I've got the Princeton Tec apex, the one that takes standard AA batteries.
It's pretty much bomb proof and lasts a session no problem.
The main beam has no focus, which is a pain when cliff fishing,
Imo, if it had a tight main beam it would be the ultimate fishing headlamp.
I've got most of the Cree lamps and they are ok back ups. I'm still looking for the 'perfect' lamp.
