* **Spotlights** are used to focus light on a specific area.
* **Floods** are used to bathe an area in light.
* **Striplights** are used to create a long, narrow beam of light.
* **Ellipsoidals** are used to create a soft, diffuse light.
* **PAR cans** are used to create a bright, focused beam of light.
### 1.4 Lighting Design
Lighting design is the process of planning and executing the lighting for a stage performance. The lighting designer must consider the following factors:
* The size and shape of the stage

## Chapter 3: Lighting Equipment
### 3.1 Lighting Fixtures
Lighting fixtures are the devices that hold and power the lighting instruments. There are a variety of different lighting fixtures available, including:
* **PAR cans** are used to create a bright, focused beam of light.
* **Ellipsoidals** are used to create a soft, diffuse light.
* **Striplights** are used to create a long, narrow beam of light.
* **Floods** are used to bathe an area in light.
### 3.2 Lighting Control Systems
Lighting control systems are used to control the intensity, color, and position of the lighting instruments. There are a variety of different lighting control systems available, including:
* **Manual control systems** are the most basic type of lighting control system. They allow the user to manually adjust the intensity, color, and position of the lighting instruments.
* **Automated control systems** are more complex than manual control systems. They allow the user to program a series of lighting cues that can be recalled during the performance.
### 3.3 Lighting Accessories
There are a variety of lighting accessories that can be used to enhance the effects of the lighting. These accessories include:
* **Gobos** are used to project patterns of light onto the stage.
* **Color filters** are used to change the color of the light.
* **Diffusers** are used to soften the light.
* **Scrims** are used to reduce the intensity of the light.
