Review this old test:

1)          Name the language that we use in lighting.

DMX 512

2)          How many pins are used in audio cables?

Lighting and Audio cable with XLR connectors look alike.  Look for the pins:  3 pins in audio cable, 5 pins in most lighting cables (these are DMX cables).

3)          In lighting communication, how many pins does a lighting cable typically have?

typically 5 pins, but some still have only 3 pins

4)          What type of light would you use to light a soloist (for example a singer or guitar solo)?

Spotlight or Ellipsoidal Reflector Spotlight

5)          The power formula is named after which State in the U.S.?

West Virginia à W=VA

6)          If a lamp gives off 1500w of power and 150v are supplied, how many amps are drawn?

W=VA             à        1500w=(150v)A          à        A=10amps

7)          If one lighting fixture is rated at 1000w and another is rated at 500w, how many total watts are drawn?

1000w + 500w = 1500w

8)          If 120v are supplied to the light and the circuit draws 10a, how many watts of power is the lamp giving off?

W=VA             à        W=(120v)(10a)           àW=1200w

9)          What type of electrical plugs are on the instruments over the stage?

stage pins

10)      Name two main differences between a stage pin connector and an Edison.

stage pin = stronger, can handle 20amps, larger

Edison = can usually only handle 15amps, smaller

11)      Name one way the form of the beam of a Fresnel can be manipulated.

The beam can be made larger or smaller by running the lamp closer to or farther away from the lens.

12)      What is the main use of an Ellipsoidal?

As a spotlight.

13)      What is the main goal of the lighting designer?

To make the stage visible. Visibility.

14)      Name 2 ways of causing a light to have movement.

1) Varying the intensity.  2) Changing the direction it is pointed while it is on. 3) Changing the color while it is on. 4) Changing the pattern while the light is on.

15)      When changing how much light comes out of the lighting instrument, we say we are varying the what?

Intensity

16)      Name 2 types of color medians.

Gels and Dichroics.

17)      How many channels can a dimmer control?

0.  Zero.  Dimmers can NOT control channels.

18)      How many dimmers can a channel control?

As many as the control board that you are using will allow.

19)      How many circuits does one light need to turn on?

Only one.

20)      As a lighting designer, describe how you would light a cold, moonlit, night scene using at least 3 of the qualities of light.

This is one way à Color: Blue; Intensity: low; Form: soft edges; Direction: low angles

21)      As a lighting designer, describe how you would light a warm, sunny, day scene using at least 3 of the qualities of light.

This is one way à Color: yellow and/or amber; Intensity: high; Form: sharp edges; Direction: steep angles

22)      Describe one example of 3D modeling.

            Causing the face of a person to look real and not flat by allowing the face to have wrinkles and show other natural curves.  Also, in some commercials, the models will be lit from a steeper angle to make the lines of the abs look more defined.

23)      What is the filament?

The wire inside the bulb that heats up electrically to give off light.

24)      Name 3 parts of an Ellipsoidal.

Lens, lamp, shutters, yoke, c-clamp, plug, lens train (or lens assembly), reflector, etc.

25)      Changing the beam on a Fresnel is called changing the beams what?

Form.

26)      When someone is on a tall ladder, how many people should be holding the bottom of the ladder AND why?

         SAFETY! 2 at the bottom of the ladder to provide counter balance (weight) so that the ladder does not tip over.  Also, if the ladder is on wheels (casters), the 2 people at the bottom prevent the ladder from rolling which can cause the person on top of the ladder to fall.

27)      Name 3 ways the form of an Ellipsoidal beam can be manipulated.

         1) Using shutters. 2) Running the lens train to make the beam softer or sharper. 3) Placing a template inside the fixture

28)      Put these in order from Lighting Designer to Actor: circuit, light fixture/instrument, light control board, dimmer, DMX cable

Lighting Designer ----> light control board ----> DMX cable ----> dimmer ----> circuit ----> light fixture/instrument ----> actor

29)      Why is a ParCan considered a wash light?

Because the beam is usually large and smooth, allowing light to “wash”, or fill, the stage.

30)      Name the 5 qualities of light.

Intensity, Form, Color, Direction, Movement

31)      Describe, or give one example of, lighting composition.

Separating different elements of the stage; i.e. having a class in a white pool of light while the rest of the stage is in darkness.

32)      When you are on a ladder, what should you do with your tools AND why?

Tie them to something.  Usually, the tools will have safety cords (or cables or chains) so that you can tie them to your wrist.

BONUS POINTS: (3 points each) 

What is the name of the manufacture of the 3 types of lighting fixtures we have here?

            Altman

What is the name of the type of template used in robotic lighting?

            Litho

What is the typical voltage (range) supplied in a wall outlet?

Typically 120v. But voltage can be found to range from 90 to 130 in some outlets.

What is another name for an extension cord?

            Jumper or stinger.

What is XLR?

            XLR is the type of connector that is on DMX cable.

If someone asks for a bulb, what should you give them?

            The glass part of the lamp.
