If you want to know more about Lucifer, besides using the Enns provided by
@Xenophon you can start using the library and study the books related to Lucifer that we have in the Book Shares section of WizardForum.
As for an opinion on Lucifer, he is a strong Demon with several (and more than several) years of knowledge who, if you wish to really collaborate with him, can grant you a lot of things, from money to energy and spiritual power.
I can say that from my past workings with Him, that he is a good Demon to summon if you want to acquire knowledge and a lot of metaphysical power.
Here are some more details to help you with your summoning
@Konstantin :
Day that he is even stronger: Friday*
Metals: Gold and copper
Planet: Venus (darker side of it as He is a Demon)
Offerings: Physical offerings to Lucifer can include copper items, incense, or candles. Personal letters expressing your intentions are also appreciated. However, the most valued offering is your commitment to the pursuit of knowledge, wisdom, and self-improvement.
Animal companion: The Peacock, with its beautiful display of eyes on its tail, is often seen as Lucifer's animal companion. The peacock symbolizes beauty, pride, and immortality, aligning well with Lucifer's aspects.
Hope that helped
