No. I don't think anyone tried. We didn't know about light magic until the Wicked Witch, although light magic predates that chronically. We haven't seen Glinda try to use magic on Zelena, we didn't even see her use magic, besides teleport. Arguably, the sorcerer may be the greatest practitioner of light magic, assuming he uses it. Emma should be more powerful that Regina, at least when it comes to light magic, since True Love is the most powerful magic of all, which Emma is the product of.

In some form of debate, there should be no such thing as light and dark magic, since things aren't so black and white in terms of morality and character. Especially since Emma and Regina can presumably do the same form of magic ( fire spell, teleporting objects, telekinesis, etc)
