Mounting stage lighting properly is crucial for performance aesthetics and safety. Among the most popular fixtures used in live shows, concerts, theaters, and churches are PAR 64 LED stage lights. These versatile lighting instruments offer high brightness, color mixing, and long lifespan. However, many technicians and event crew members—especially beginners—struggle with how to correctly mount them to a light bar or truss.
This comprehensive guide will walk you through everything you need to know, from selecting hardware and tools to safety standards and real-world examples. Whether you’re a mobile DJ, church AV technician, or lighting professional, this guide will help you securely and efficiently mount your PAR 64 LEDs.
What Are PAR 64 LED Lights?
PAR 64 LED lights are modernized versions of traditional PAR can lights. The term "PAR" stands for Parabolic Aluminized Reflector, and "64" refers to the size (8 inches in diameter).
Key Features:
- RGB or RGBW color mixing
- Energy-efficient LED source
- Long operational life
- DMX controllable
- Compact and lightweight compared to halogen counterparts
Use Cases:
- Concert stages
- Houses of worship
- Mobile DJ setups
- Theater productions
Example: The Rasha Professional PAR 64 LED fixture offers high output, built-in programs, and robust construction—making it ideal for both fixed and mobile applications.
Understanding Light Bar vs Truss Mounting
Before mounting any fixture, it's essential to understand the structural elements you’re attaching them to.
Light Bar (T-Bar)
- Typically used in portable lighting setups
- Mounted on tripod stands
- Ideal for mobile DJs or small productions
- Limited weight capacity
Truss
- Used in large-scale productions and permanent installs
- Comes in various shapes: box, triangle, ladder
- Stronger and more versatile
- Often paired with crank stands or flown from ceilings
Light Bar Pros:
- Quick to set up
- Lightweight and mobile
Truss Pros:
- Supports multiple fixtures and heavier loads
- Offers greater creative flexibilit
Tools and Hardware You’ll Need
Before beginning the mounting process, gather the following tools:
Clamps:
- C-Clamp: Basic clamp for attaching to T-bars
- O-Clamp: Rubber-coated for aluminum truss
- Trigger Clamp: Easy to operate with one hand
Safety Gear:
- Safety cables: Required for all overhead fixtures
- Work gloves
- Multimeter (optional): To check power
Installation Tools:
- Adjustable wrench
- Screwdrivers (Phillips and flathead)
- Zip ties or gaffer tape
- Power and DMX cables
Pro Tip: Always check that the clamp’s weight rating exceeds the fixture’s weight.
Safety Guidelines Before Mounting
Mounting lights improperly can result in injury or damage. Always follow these safety practices:
- Use Safety Cables: Every fixture mounted overhead must have a safety cable as a backup in case the clamp fails.
- Check Weight Ratings: Never exceed the weight capacity of a light bar or truss.
- Secure All Cables: Prevent trip hazards and unintentional disconnections.
- Verify Fixture Orientation: Pointed downward lights must be double-secured.
- Test Rig Before Powering On: Perform a tug test on each clamp and cable.
⚠️ Warning: Never rely solely on clamps. Safety cables are a critical secondary restraint.
Step-by-Step Guide: Mounting PAR 64 LEDs on a Light Bar
- Select Fixture Location:
- Distribute lights evenly for balance
- Center heavier lights to avoid toppling
- Attach Clamp to Fixture Yoke:
- Insert clamp bolt through yoke
- Tighten using wrench until snug
- Place Fixture on Light Bar:
- Position the clamp over the bar
- Secure clamp bolt tightly
- Add Safety Cable:
- Loop around light bar and through yoke
- Attach using carabiner or quick link
- Adjust Fixture Angle:
- Use side knobs to tilt fixture
- Connect Power & DMX:
- Use DMX daisy chain or splitter as needed
- Test Lighting Controls:
- Verify DMX signal, color mixing, and dimming
Step-by-Step Guide: Mounting PAR 64 LEDs on a Truss
- Inspect Truss for Load Rating:
- Use manufacturer specs for max load per foot
- Attach Clamp to Fixture:
- Use O-clamps for aluminum truss
- Mount Fixture to Truss:
- Secure clamps across a truss cross member
- Keep fixtures evenly spaced
- Secure Safety Cable:
- Loop around truss and back to fixture
- Route DMX and Power Cables:
- Use zip ties or Velcro
- Avoid loose cable runs
- Test All Fixtures:
- Ensure each fixture responds to DMX commands
DMX and Power Considerations
- Power:
- LED PAR 64s use significantly less power than halogen
- Avoid chaining too many fixtures on one circuit
- DMX:
- Assign unique addresses to each fixture
- Use terminators at the end of the DMX chain
- Label each fixture for quick troubleshooting
- Cable Routing:
- Keep signal and power lines separate when possible
- Use cable looms or raceways for permanent installs
Mistakes to Avoid While Mounting
- Using incompatible clamps
- Overtightening bolts (can warp yoke)
- Ignoring safety cable installation
- Uneven weight distribution
- Tangled or unsupported cabling
- Skipping DMX termination
Real-World Mounting Examples
1. Mobile DJ Setup (T-Bar):
- 2 PAR 64s mounted with C-clamps
- Daisy-chained DMX with wireless controller
2. Church Installation (Ceiling Truss):
- Box truss rig with 8 PARs and 4 moving heads
- DMX interface routed to control booth
3. Concert Tour (Crank Stands + Truss):
- Goalpost truss system with even weight load
- PAR 64s and blinders mounted using O-clamps
- Quick disassembly setup
Example: Rasha Professional PAR 64 LEDs used in concert stage with crank-up truss for fast deployment
Maintenance and Inspection Tips
- Inspect clamps and bolts before each event
- Replace frayed safety cables immediately
- Test DMX cable continuity
- Clean fixture lenses with microfiber cloth
- Rotate angle knobs monthly to prevent freezing
Frequently Asked Questions (FAQs)
Q: What clamp is best for PAR 64 LED lights?
A: O-clamps are best for aluminum truss; C-clamps work for T-bars.
Q: Can I mount PAR lights without a truss?
A: Yes, you can use a light bar with a tripod stand for mobile setups.
Q: Do I need a safety cable?
A: Absolutely. It’s a critical backup even for lightweight LED fixtures.
Q: How high should I mount my PAR 64s?
A: Between 10–14 feet depending on the throw distance and beam angle.
Q: How many PAR 64s can I daisy chain?
A: Up to 32 devices per DMX line, but use signal boosters for long runs.
Q: Do I need a DMX terminator?
A: Yes, especially with longer cable runs to avoid signal issues.
Final Tips and Best Practices
- Label fixtures and cables for speed
- Pack spare clamps, fuses, and DMX cables
- Always perform a live test before the show
- Review truss load capacity before adding fixtures
- Double-check all clamp bolts and safety cables after transport
Conclusion
Mounting PAR 64 LED stage lights correctly is not just about functionality—it’s about safety, efficiency, and professionalism. Whether you’re rigging a full concert truss or setting up a mobile light bar, following these step-by-step practices will ensure a seamless and secure lighting setup. Always double-check your gear, use proper safety measures, and continue learning from every setup.
