Howdy AZPops,
In case you're actually looking for a penlight, there are a few that fit the "tactical" label, in that they can be set to come on in their brightest level:

I don't own either one, but I've been looking for a good penlight for a while now (haven't found one that fits all my criteria), so I know a bit about both of these. Both offer two levels.
The Brightstrike EPLI seems like a nice light, but sounds like it has a somewhat ringy beam and cool white emitter, and I couldn't find any mention of a warranty. It comes on in high, and might be able to come on in low.
The EagleTac PN20A2 seems to be well built, has a lifetime warranty, has a slightly more throwy beam (but comes with a diffuser), can be set to come on in either high or low, and is offered with either a cool white or neutral LED.
Of those two, the EagleTac neutral would be my pick.
However, if 007 had to pick a penlight from today's market, I think he might go with the Peak 2xAAA Eiger offered by Oveready.com:

A bit expensive if configured with the QTC and momentary switch, but elegant and built like a tank.
Coming in at a close 2nd place would be the Preon 2 black tie, for it's stunning good looks and elegant simplicity.
Good luck in your search!
