  1. what are the properties of light
    • intensity
    • color
    • movement
    • distribution (like angle, focus, hard/soft edge, etc)
  2. circuits
    • 2 types;
    • Parallel- a bunch of wires connecting the lights
    • Series- one wire connecting the lights
  3. Ellipsoidals
    • also called Source four or ERS
    • long ones with shutters
    • has several lenses
    • gobo can be used
    • mounted far away from stage
  4. Scoop
    • soft light
    • no lenses
    • colored gel
    • mounted close to stage
    • floodlight
    • used to cover the stage in blue
  5. Fresnel
    • mounted close to stage
    • short and square
    • 1 lense
    • soft light
  6. Dimmer
    controls the amount of electricity sent out
  7. circuit (in a lighting system)
    • pathway for electricity to flow
    • outlet in the wall
    • number that you plug the light into
  8. channel
    • how the lightboard talks to the system
    • controls the dimmer
  9. Standard Voltage
    120 volts
  10. W=VA
    • W is watts
    • V is volts
    • A is amps
    • W= 120 * amps
  11. 1. Cable
    2. Jumper
    3. 2 -fer
    • 1. extention cord
    • 2. cord that is 5 feet or less
    • 3. lets you plug 2 instruments into one
  12. McCandless Method
    • theory of lighting plots to recreate 3:00pm
    • 45° angles
    • warm and cool lights
    • Key light- brighter light, main source
    • Fill light- filling in the shadows, lower light
  13. 3 primary colors of light
    • red
    • blue
    • green
    • these 3 together create white light
  14. watts
    the actual power
  15. amps
    flow of electricity or power
  16. dimmer capacity
    how much wattage you are able to have on the dimmer
  17. volts
    potential power and pressure
  18. intensity
    how bright something is
  19. dimmer load
    how much wattage you actually have on the dimmer
  20. Gobo
    • light pattern that you insert into an ERS
    • it is a type of "color media"
  21. gel
    • colored plastic
    • this is a type of "color media"
  22. types of connectors used
    • 20 amp stage pin (the square kind we use in Belk, 3 prongs)
    • 20 amp twist lock (round kind with 3 prongs)
    • 15 amp edison (normal plug)
  23. Wires
    • ground wire is green
    • Neutral wire is white
    • hot wire is black
  24. soft and hard patching
    • soft patching- do it on the light board with the computer
    • hard patching- physically plug the lights in
  25. Alternating current
    Direct current
    • electricity used with batteries
    • electricity from the wall
