I've never had a bad experience with a Maglite. I own the 6 D-Cell Version as well as several Mini Mags and I've never seen a light as rugged and dependable.
The 6 D-Cell version is about the length of a billy club and could easily be used as such, considering the weight. It's bright enough to cut a beam clear across a 200 yard wide pasture and light up whatever it is you might be looking at...
As for my opinion on this matter, you're splitting hairs "This light vs. That"
If it's about protection... Buy her a big heavy D-Cell Mag and a featherweight hammerless S&W .38 Special
Just my
