Installing exterior lighting is a critical step in enhancing the security, safety, and aesthetic appeal of commercial and residential properties. Among the various options available,Wall Pack Lightsstand out as a robust solution for illuminating building perimeters, walkways, and entryways［1］.
However, installing these fixtures on masonry surfaces, specifically brick facades, presents a unique set of challenges compared to siding or drywall. Improper installation can lead to water infiltration, structural damage, or fixture failure. This comprehensive guide details the professional methodology for installing LED Wall Pack lights on brick, ensuring a secure, weatherproof, and code-compliant setup.
Understanding Wall Pack Lighting
Wall packs are outdoor lighting fixtures mounted to the exterior walls of buildings. Historically used with Metal Halide or High-Pressure Sodium bulbs, modern iterations predominantly utilizeLED technologydue to their superior energy efficiency, longevity, and reduced maintenance costs［2］.
When selecting a fixture for installation, it is vital to consider theIP Rating (Ingress Protection). For exterior wall packs, an IP rating or higher is recommended to ensure the fixture is dust-tight and protected against water jets［3］.
Tools and Materials Required
Before commencing the installation, gather the necessary tools. Working with brick requires specific masonry tools that differ from standard electrical installations.
Essential Tools:
- Power Drill:A heavy-duty corded drill or a high-torque cordless drill.
- Hammer Drill Function:Essential for drilling into brick and mortar.
- Masonry Drill Bits:Sized according to the wall anchors (typically 1/4" or 3/8").
- Screwdrivers:Flathead and Phillips head.
- Wire Strippers and Cutters.
- Voltage Tester:To ensure power is off.
- Level:To ensure the fixture is straight.
- Pencil:For marking drill holes.
- Safety Gear:Safety glasses and gloves.
Materials:
- The LED Wall Pack Fixture.
- Masonry Anchors:Sleeve anchors or wedge anchors (usually included, but high-quality stainless steel is preferred).
- Silicone Caulk:100% silicone, paintable, exterior grade.
- Wire Nuts:Appropriate gauge for the wiring.
- Electrical Tape.
Pre-Installation Planning
Choosing the Location
The placement of the wall pack determines its effectiveness. For security purposes, lights should be placed at entry points and dark corners. For general area lighting, spacing is calculated based on thephotometric distributionof the light［4］.
Note:Ensure the chosen location is near an existing power source (junction box). If running new wire is required, conduit must be used to protect the wiring along the brick facade.
Mounting Height
Standard mounting height for wall packs typically ranges betweento 1 feet(2. to 3. meters) above the ground［5］. This height minimizes glare while maximizing light spread.
Safety First
Turn off the power.Locate the circuit breaker controlling the outdoor lighting circuit and switch it to the "OFF" position. Use a non-contact voltage tester on the existing wires to confirm there is no active current.
Step-by-Step Installation Guide
Step 1: Prepare the Junction Box
If there is an existing junction box on the brick wall, ensure it is weatherproof. If the box is recessed, you may need a box extender to bring the connection point flush with the surface of the brick, preventing wire compression［6］.
Step 2: Position the Fixture
Most LED wall packs feature a "backplate" or mounting bracket that attaches to the wall first.
- Feed the supply wires through the center hole of the mounting bracket.
- Hold the bracket against the brick wall in the desired position.
- Use alevelto ensure the bracket is perfectly horizontal.
- Mark the position of the mounting holes on the brick or mortar with a pencil.
Step 3: Drilling into Brick vs. Mortar
A common debate in masonry installation is whether to drill into the brick or the mortar joint.
- Drilling into Brick:Offers the strongest holding power. Bricks are dense and less likely to crumble over time. This is the recommended method for heavy fixtures［7］.
- Drilling into Mortar:Easier to drill but softer. Over time, weathering can cause mortar to crumble, potentially loosening the anchor.
Procedure:
- Put on safety glasses.
- Set your drill to "Hammer" mode.
- Using a masonry bit slightly smaller than your anchor diameter, drill into the marked spots.
- Drill to a depth slightly deeper than the length of the anchor.
- Clean the holes:Use compressed air or a vacuum to remove brick dust. Dust in the hole can prevent the anchor from seating correctly［8］.
Step 4: Securing the Bracket
- Insert the masonry anchors (sleeve or wedge anchors) into the drilled holes. Tap them gently with a hammer until they are flush with the bracket.
- Tighten the bolts/nuts to secure the bracket firmly against the wall. Do not overtighten to the point of cracking the brick.
Step 5: Electrical Wiring
Connect the fixture wires to the building's supply wires.
- Black (Live/Hot):Connect fixture black wire to supply black wire.
- White (Neutral):Connect fixture white wire to supply white wire.
- Green or Bare Copper (Ground):Connect to the supply ground wire or the grounding screw in the junction box［9］.
Twist the wires together clockwise and secure them with wire nuts. Wrap the connection with electrical tape for added moisture protection.
Step 6: Mounting the Housing
Once the wiring is tucked safely into the junction box, align the main housing of the wall pack with the mounting bracket. Secure it using the provided screws. Ensure the gasket (rubber seal) is properly seated to maintain the IP rating.
Step 7: Weatherproofing
This is a critical step often overlooked.
- Apply a bead ofsilicone caulkaround the perimeter of the mounting bracket where it meets the brick.
- Pay special attention to the top edge to prevent water from seeping behind the fixture and running down the wall［10］.
- If using a conduit, seal the entry point as well.
Step 8: Final Adjustments and Testing
- Install the LED module or ensure the integrated LED board is secure.
- Adjust the angle of the light if the model allows for tilting.
- Restore power at the circuit breaker.
- Test the light.
Troubleshooting Common Issues
Even with careful installation, issues can arise. Here are common problems and solutions:
| Issue | Potential Cause | Solution |
|---|---|---|
| Light flickers | Loose wire connection or incompatible dimmer. | Check wire nuts and ensure the switch is rated for LED loads. |
| Fixture loose | Anchor spinning in the hole. | Remove anchor, fill hole with epoxy or larger anchor, and re-drill. |
| Moisture inside lens | Broken seal or improper caulking. | Remove fixture, dry components, re-apply silicone gasket/caulk. |
| Light doesn't turn on | Tripped breaker or faulty photocell. | Check the breaker panel. Bypass the photocell to test the LED driver. |
Maintenance and Best Practices
To ensure your Wall Pack Lights last for their rated lifespan (often 50,000+ hours), minimal maintenance is required.
- Cleaning:Dust and grime can accumulate on the lens, reducing light output (lumens). Clean the lens annually with a damp cloth and mild detergent［11］.
- Inspect Seals:Check the silicone caulking every few years. If it cracks or peels, remove the old caulk and re-apply to prevent water damage.
- Photocell Check:If your wall pack uses a dusk-to-dawn sensor (photocell), ensure it is not obstructed by tree branches or other light sources, which can cause the light to cycle on and off rapidly［12］.
Conclusion
InstallingWall Pack Lightson brick facades requires patience and the right masonry tools, but the result is a professional, secure, and high-performance lighting solution. By following the steps outlined above—specifically focusing on secure masonry anchoring and rigorous weatherproofing—you can enhance the safety and visibility of your property for years to come.
For high-quality LED lighting solutions including Wall Packs, High Bays, and Panel Lights, ensure you source from reputable manufacturers that prioritize durability and photometric performance.
