Study Notes

Types of Lighting Equipment

Incandescent Lighting:
- Uses traditional light bulbs with a tungsten filament
- Warm, natural color temperature
- Not energy efficient and has a relatively short lifespan
Fluorescent Lighting:
- Uses a gas-filled tube with a phosphor coating
- More energy efficient and has a longer lifespan than incandescent lighting
- Available in various color temperatures (warm, cool, and daylight)
LED Lighting:
- Uses solid-state devices to emit light
- Energy efficient and long lifespan
- Available in various sizes and shapes (panels, strips, and bulbs)
- Offers a wide range of colors and can be easily dimmed or controlled
- Preferred for stage lighting applications
Intelligent Lighting:
- Programmable and can be controlled remotely
- Often consists of moving heads, rotating gobos, and color changers
- Used to create dramatic lighting effects and enhance the visual experience
Fresnel and Ellipsoidal Lighting:
- Used for theatrical lighting purposes
- Fresnel fixtures produce a soft, diffused light
- Ellipsoidal fixtures produce a sharp, focused beam of light
- Available in various sizes and can be equipped with different lenses
Par Cans:
- Used for stage and wash lighting
- Consist of a sealed metal container with a reflector and a lamp
- Durable and simple
- Produce a strong, narrow beam of light
- Available in various sizes and beam angles
Followspot:
- Provides an intense, focused beam of light
- Manually aimed and controlled
- Used to highlight preachers, soloists, or special performers

Lighting Terminology

Dimmer:
- Device that controls the intensity or brightness of a lighting fixture
- Allows for adjusting the amount of light emitted
Lighting Console:
- Device used to control and program lighting fixtures
- Offers various controls to manipulate fixture attributes
Fresnel:
- Type of lighting fixture with a spherical reflector and lens
- Adjustable beam angle
Gobo:
- Stencil or template used to project a specific pattern or shape onto a surface
- Often used in worship lighting to create atmospheric effects
DMX:
- Standardized protocol used in lighting control systems
- Allows communication between lighting fixtures, dimmers, and consoles
CRI:
- Color Rendering Index
- Measures how accurately a light source illuminates the colors of objects
- Scale ranges from 0 to 100, with higher values indicating better color rendering
Strobing:
- Rapid succession of intense flashes of light
- Used to create dynamic effects and evoke emotions
Beam Angle:
- Width of the light beam emitted from a lighting fixture
- Measured in degrees
- Determines the spread of light
Color Temperature:
- Perceived warmth or coolness of light
- Measured in Kelvin (K)
- Lower color temperatures produce warm, yellowish light, while higher color temperatures produce cool, bluish light
Footcandle:
- Unit of measurement for the amount of light falling on a surface
- Represents the illuminance provided by a light source at a distance of one foot

Lighting Fixtures, Control Systems, and Power Distribution

Lighting Fixtures:
- Physical devices that emit light
- Come in various types and have different features and capabilities
- Often used to create a specific ambiance or highlight specific elements of the worship space
Control Systems:
- Technologies that allow users to operate and manipulate lighting fixtures
- Provide control over brightness, color, movement, and other effects
- Include dimmers, lighting consoles, and DMX protocol
Power Distribution:
- Essential for the safe and efficient operation of lighting fixtures
- Includes power sources, circuiting, and power distribution units (PDUs)
- Important for safety considerations and best practices

Safety Considerations and Best Practices

Electrical Safety:
- Handle electrical equipment with caution
- Ensure proper knowledge and training before working with electrical systems
- Regularly inspect cables, connectors, and power distribution equipment
- Use surge protectors to safeguard against power surges
Rigging and Mounting:
- Familiarize yourself with weight restrictions and load-bearing capacities
- Ensure all fixtures and rigging equipment are properly secured and tightened
- Regularly inspect rigging hardware for signs of wear and tear
- Use safety cables as a secondary attachment method
Heat Management:
- Pay attention to heat generated by lighting fixtures
- Allow for sufficient ventilation around fixtures
- Avoid placing fixtures too close to heat-sensitive materials
- Use appropriate clamps or mounting accessories
Fire Safety:
- Regularly inspect lighting fixtures and cables for signs of overheating
- Keep flammable materials away from lighting fixtures
- Ensure smoke alarms and fire extinguishers are present and properly maintained
Personal Safety:
- Encourage personnel to wear appropriate safety attire
- Provide training on handling equipment safely and operating machinery
- Establish clear communication protocols during lighting setup and rehearsals
