Zebralight, all the way. I have a model using an 18650 which is just about perfect, in use daily when I read in bed before dozing off. There are several AA models as well as CR123's all of which ramp up from low to high. An AA model is always in my hiking/field pack. I have equipped the wife and darling daughter with similar models. All work quite dependably

I think "tactical"is just mall ninja/marketing hype. It seems to denote a crenelated bezel and implied use of the light as an impact weapon. I believe many, if not most, jurisdictions forbid such use.

There are lots of other decent brands as well (Nitecore, Fenix to name a couple I have used) but others as well. The general quality in headlamps and flashlights is far superior to what was generally available even twenty years ago.
