The awesome Backstage Jobs Blog has posted a comprehensive chart of various stage lighting fixtures along with what type of bulb each takes. Not a particularly glamorous set of information, but I think a lot of you will find it quite handy to bookmark. Should save you a few trips up to the catwalk. What I love is that most of the instruments have accompanying photos for us visual-learner-types.
If you’re completely hopeless, let me shamelessly plug the two lighting DVDs (Lighting Design and Lighting for Theater) in the Practical Technical Theatre series we carry. They’re both brilliant resources for learning about and teaching lighting.
