What is the difference between LED PAR lights and LED BAR lights in terms of application?
Stage lighting professionals often face the challenge of selecting the optimal fixture for their specific production needs. This article provides a direct comparison between LED PAR lights and LED BAR lights, focusing on their unique applications in stage lighting. Armed with this knowledge, professionals can make informed, efficient decisions.
Overview: LED PAR Lights vs. LED BAR Lights
- LED PAR Lights:
- PAR stands for Parabolic Aluminized Reflector
- Emit strong, focused beams of light in circular patterns
- Commonly used as theatrical wash or spotlighting fixtures
- LED BAR Lights:
- Consist of multiple LEDs in a linear (bar) configuration
- Deliver even, horizontal washes or dynamic, color-changing effects
- Suited for wall washing, cyclorama lighting, and architectural effects
Key Application Differences
Application Scope
- LED PAR Lights:
- Ideal for front, back, or side wash lighting on performers
- Used for accenting specific areas, objects, or talent on stage
- Suitable for creating mood and focus by highlighting key points
- Cited in industry guides such as the USITT Lighting Handbook
- LED BAR Lights:
- Best for coloring large, flat surfaces (walls, backdrops, set pieces)
- Frequently deployed for cyc lighting and scenic backgrounds
- Enable smooth fades and dynamic color chasing across a horizontal plane
- Referenced by Electronic Theatre Controls (ETC) for architectural integration
Flexibility & Control
- LED PAR Lights:
- Modular; easily repositioned and refocused
- Typically offer selectable beam angles (narrow to wide)
- DMX controllable for intensity and color (multi-chip models)
- Great for quick setup and portable stage events
- LED BAR Lights:
- Length and pixel-mapping enable advanced visual effects
- Fine control over segments or pixels for complex chases
- Often incorporate RGB, RGBW, or RGBA mixing per segment
- Favored in touring, broadcast studios, and creative productions
Effect on Stage Design
- LED PAR Lights:
- Enhance depth and drama through high-contrast accenting
- Maintain spotlight focus without significant “spill”
- Blend well in traditional theatrical setups
- LED BAR Lights:
- Emphasize breadth and seamless blends across surfaces
- Excellent for filling space with uniform color and movement
- Used in modern designs for striking visual environments
Practical Considerations
- LED PAR Lights:
- Available in multiple sizes and wattages (e.g., PAR64, PAR56)
- Robust and compact, suitable for mobile rigs
- Widely compatible with generic stage lighting systems
- LED BAR Lights:
- Variable lengths (typically 1m, 50cm, or custom)
- Can double as blinder effects in concerts or corporate events
- Flexibility in mounting for creative installation patterns
Choosing the Right Fixture
- Assess required beam shape, coverage area, and effect.
- Consider power draw and installation ease.
- Reference on-site needs; consult manufacturer specifications (e.g., KIMU, Chauvet, ETC).
- Refer to standards from organizations like PLASA and ESTA for compliance.
