Chassidim seem to follow the views of kabbalah to a greater degree than non-Chassidim.
What status does kabbalah have in determing the practical halacha for non-Chassidim?
Kabbalah is not binding for both non-Hasidim and Hasidim, simply because it is not of legalistic nature; it belongs to the occult field of Judaism. However those of Hasidic bent, not necessarily of the Hassidic movement (Hasidism) but of Hasidic behavior (Pious), chose to be bound by some of the Kabbalah in order to incorporate spiritual elements into their lives. On the other hand, non-Hasidim refer to Kabbalah to enhance their understanding or knowledge of different areas of Judaism. In instances where non-Hasidim act in accordance with Kabbalistic ordinances it is not because they are bound to do so but rather because at some point a predecessor adopted any certain practice and it became their custom (minhag).
(See Jacobs' 'A Tree Of Life' pg. 69 for a general observation of the influence of kabbalah on halachah.)
