Very odd lighting bug

[richm0nkey]

So odd words cant really accurately explain it. Screen shots and video below. The only lights I have is 1 enormous box light and 1 enourmous spot light (for shadows.) And the torches

EDIT:
The basic problem is when the player rotates their head the lighting makes weird triangular shapes and those shapes rotate and follow the player. best way i can describe it with words just watch the video you'll see

Another note about the third screenshot, I found when I looked at the ground the issue almost completely disappears. Only when i look down though.
