Kyle's white lantern ring isn't the same as Blackest Night's white lantern ring. He didn't get it from the life entity, he got it from combining all the colors of the emotional spectrum, and it never showed the same powers as during Blackest Night (He never brought someone back to life, and the entity didn't speak to him as it did to white light users during Brightest Day.)

And according to the writer its just a portion of his true power. So you can guess how powerful he is.
