What's the difference between Luciferian Witchcraft and Paganism/ Wicca?

I am doing a Personal Interest Project on Witchcraft and i was wondering if someone would be able to clearly articulate what the difference between Luciferian Witchcraft and Paganism/ Wicca is. i know there is a major difference, and that magick is used for different purposes within each path, but i am unable to clearly define the differences between the two. please help! :)
