Scope out your target—look for power sources, check to see that they are live. Walk out the distance from your light to the target wall, and draw a map (long step is 3 feet and a regular step is 2 feet)—you will need this to figure out which lens to put on your source four light—also measure the width of your target—see chart at left for distance, field diameter and illumination. I have found that a 10° lens gives me the brightest image and longest throw, I hit the top of a 30 story building with that one. Phil at the Backbone Campaign recommends a 15-30° zoom, that’s a wider image and less bright, but more versatile.
I will caution you that light protest is a powerful tactic and you should use it wisely with discretion.
Strategy: How will the tactic move us toward achieving our goal?
Message: What will the tactic communicate? What will it mean to others? How will it carry a persuasive story?
Tone: Will the action be solemn, jubilant, angry, or calm? Will the energy attract or repel the people we want to engage?
Timing: Can we leverage unfolding events and new developments as opportunities? Does the political moment hold potential for us, or vulnerability for our opponents?
Audience: Who do we want to reach with our tactic? What response do we want our action to inspire in them?
Allies: How will the tactic affect our allies or potential allies? How will they receive it? Will it strengthen the relationship or jeopardize it?
Resources: Is the action worth our limited time, energy and money? Can we get more out of it than we put in? Do we have the capacity to pull it off effectively?
Target: What message will the tactic send to the people who have the power to meet our demands? Will it pressure them to capitulate, or enable them to dismiss us or retaliate?
I highly recommend the book Beautiful Trouble: A Toolbox for Revolution, for a complete discussion of tactics and related principles and theories.
