Mulberry Lighting Videos
The Village Theater company has made a comprehensive series of videos on the lighting system at Mulberry. I think the videos are quite good.
They have also made comprehensive series of videos on other technical theater topics, also very good.
You'll need to 'enroll' in their system to view them. No big deal, no charge, you just create a login / password pair. I think it is worth your effort. They can found at VTC training Videos.
