Hi Ash. Welcome to the forum.
If you want a slightly sleeker, but tougher alternative to the that C8, this light may interest you. There is a group buy in the works at the moment for it here.
That light for you GF is nice if you want her to have both flood and throw options in the same light. You loose a good deal of the lumen output in those aspheric lights. It's a compromise. A more general purpose light like the Convoy 18650 tube lights might be a better alternative depending on how she will use it.
Best Wishes
