These are really nice.  The globe portion of the lights is really thick and heavy, not flimsy, so no worries about breakage.  I actually purchased these for my front railing to accent my Christmas decor so have not placed them out anywhere yet (although that may change if I find another spot to use them).  My guess is with the weight of the globe, these are going to look best hanging downward.  The globes do come off (several fell off in the package during transit) so make sure you secure them before use.  All and all, I am happy with this purchase.
