The Armytek Wizard is very, very good for running. Is has a special TIR-lens, thats gives it a perfectly smooth, but somewhat focused floodbeam (imagine a "carpet of light"). Many cheap lights have the "bouncing spot effect" and cause tunnel vision. With the Armytek this effect is greatly reduced. This lens is the reason why I think they are better for running than the headlamps from Zebralight (which use reflectors, sometimes together with a diffused lens). Even compared to the Zebralight models with an "F" in their name, it produces a more even beam of light.
It doesn't really matter which version you get. The more expensive "Pro"-Versions stay in regulation longer in Turbo-mode (the other modes are the same) and have additional firefly-modes (not needed for running). There are different color temperatures available. I would reccomend getting the normal, "warm" version (in reality it's a 4000K neutral white). There is also a new variant of the light with Cree XHP-50 that is much brighter in the highest mode. If you often need the light for 45min oder less, the XHP-50 version would be a nice option.
All Wizard lights use single 18650 batteries. They have over-discharge protection, so you can use unprotected batteries (cheaper than protected ones and you can get specific, high-quality cells). They all have an overtemperature protection. They will never get too hot.
The normal Wizards with Cree XM-L2/XP-L LEDs produce 600-900 otf Lumens in the highest mode, the new ones with Cree XHP-50 around 2000 (EDIT: 1600) otf lumens.
EDIT:
In general I would recommend getting a light that uses one 18650 battery instead a light with AA- oder even AAA-batteries. You get much more Energy in a still rather compact form factor. If you get the right type of cell it will also work much better in the winter, when it's cold outside.
I would also generally recommend to use a rather bright setting if you are a faster runner, are older with vision getting worse, run on difficult trails or just want to feel safer. I would never sacrifice my own safety because someone else thinks they have better eyes and decide to use a dim light. Too bad for them! But that's just my opinion.
Also: who wants to waste time waiting for their eyes to adapt to the darkness of a sub-100 lumen light?
