Wall pack lightsare robust, outdoor lighting fixtures designed to provide security and visibility around the perimeter of commercial and industrial buildings. Unlike standard residential sconces, wall packs are engineered to withstand harsh weather conditions while delivering high-lumen output［1］.
Installing these fixtures onbrick facadespresents a unique set of challenges compared to siding or stucco. Masonry requires specific drilling techniques, anchoring systems, and safety precautions to ensure the fixture remains secure and watertight. This comprehensive guide details the step-by-step process for installing LED wall pack lights on brick exteriors.
Phase 1: Preparation and Safety
Before beginning the physical installation, it is crucial to gather the necessary tools and ensure the work area is safe. Working with electricity and masonry requires precision.
Essential Tools and Materials
To successfully mount a light fixture on brick, you will need the following equipment:
- Power Drill (Hammer Drill preferred):A standard drill may struggle with hard brick; a hammer drill function pulverizes the masonry as it spins［2］.
- Masonry Drill Bits:Sized according to your anchors (typically 1/4" or 3/8").
- Wire Strippers and Voltage Tester.
- Silicone Caulk & Caulking Gun:For waterproofing entry points.
- Screwdrivers and Wrench Set.
- Ladder:Ensure it is rated for the height of the installation.
- Safety Gear:Safety glasses (essential when drilling into brick) and insulated gloves.
Electrical Safety
Warning:Always turn off the power at the main circuit breaker before attempting any electrical work. Use a non-contact voltage tester to confirm that the wires are de-energized before touching them［3］.
Phase 2: Understanding Masonry Mounting
Drilling into brick differs significantly from drilling into wood or drywall. The structural integrity of the installation depends on where and how you drill.
Brick vs. Mortar Joints
A common debate in masonry mounting is whether to drill into the brick itself or the mortar joint.
- Drilling into the Brick:This is generally the recommended method for heavy fixtures like LED wall packs. Bricks offer superior holding strength for expansion anchors. However, there is a risk of cracking the brick if the drill bit wanders or if too much pressure is applied［4］.
- Drilling into Mortar:While easier to drill, mortar is softer and can crumble over time, potentially loosening the anchor. It is usually reserved for lighter loads.
For high-outputLED Wall Packs, which can be heavy due to heat sinks, anchoring directly into thebrick unitis the industry standard for longevity.
Phase 3: Step-by-Step Installation Guide
Follow these steps to ensure a professional and code-compliant installation.
Step 1: Positioning and Marking
Hold the wall pack's mounting bracket against the desired location on the brick wall.
- Ensure the junction box opening aligns with the existing electrical supply line.
- Use a level to ensure the bracket is perfectly horizontal.
- Mark the drill holes using a pencil or a masonry marker.
Note:If you are replacing an old fixture, check if the existing holes are still viable. If the old anchors are loose, you must drill new holes slightly offset from the originals.
Step 2: Drilling the Pilot Holes
Put on your safety glasses. Insert the masonry bit into your hammer drill.
- Align the bit with your marks. Start the drill at a slow speed to create a "dimple" that prevents the bit from wandering across the smooth face of the brick［5］.
- Once the dimple is established, increase the speed and apply steady pressure. Engage the hammer action of the drill.
- Drill to the depth required by your anchor length. You can mark the depth on your drill bit using a piece of masking tape.
Step 3: Installing Anchors
Clean out the dust from the newly drilled holes. Compressed air or a vacuum works best for this; blowing with your mouth is often ineffective and can introduce moisture［6］.
- Insert the masonry anchors (wedge anchors or sleeve anchors are recommended) into the holes.
- Tap them gently with a hammer until they are flush with the surface of the brick.
Step 4: Wiring the Fixture
Prepare the wall pack for wiring. Most commercial LED wall packs come with a pre-installed short pigtail wire.
- Strip about 1/ inch of insulation from the building's supply wires and the fixture's wires.
- ConnectBlack to Black(Live/Hot),White to White(Neutral), andGreen/Bare Copper to Green(Ground).
- Secure the connections using UL-listed wire nuts. For outdoor fixtures, it is best practice to wrap the wire nuts in electrical tape or use waterproof wire connectors to prevent corrosion［7］.
Step 5: Mounting the Fixture
Carefully tuck the wires into the junction box or through the back of the fixture. Align the fixture’s mounting holes with the anchors you installed in the brick.
- Insert the mounting screws/bolts through the fixture and into the anchors.
- Tighten securely using a wrench or socket driver. Do not overtighten, as this can strip the anchor or crack the fixture housing.
Step 6: Weatherproofing (Crucial Step)
Water infiltration is the enemy of outdoor electronics. Even with a gasket, water can seep behind the fixture.
- Apply a bead of clear silicone caulk along the top and sides of the fixture's mounting plate.
- Do not caulk the bottom edge.Leaving the bottom open allows any condensation that builds up inside the fixture to drain out［8］.
Phase 7: Technical Considerations
When upgrading to modern LED Wall Packs, several technical factors influence performance and compliance.
Photocells and Controls
Most modern wall packs feature a twist-lock receptacle for a photocell. This device turns the light on at dusk and off at dawn automatically.
- Installation:Simply plug the photocell into the receptacle on the fixture.
- Orientation:Ensure the sensor faces away from other light sources to prevent "fighting" (where the light turns off because it senses its own reflection)［9］.
Dark Sky Compliance
Many municipalities now require "Dark Sky" compliant fixtures to reduce light pollution. These fixtures, often calledcutoff wall packs, direct light downward rather than allowing it to spill upward above the horizon line［10］. When installing, verify local zoning laws regarding light trespass.
IP Ratings
Ensure your chosen fixture has an appropriate Ingress Protection (IP) rating. For outdoor wall mounts exposed to rain, a minimum ofIP65is recommended. This certifies that the fixture is dust-tight and protected against water jets from any direction［1］.
Troubleshooting Common Issues
| Issue | Possible Cause | Solution |
|---|---|---|
| Flickering Light | Loose neutral wire or incompatible dimmer. | Check wire nut connections; ensure the switch is rated for LED loads. |
| Fixture Humming | Driver vibration or loose mounting. | Tighten mounting screws; ensure the driver is secured within the housing. |
| Premature Failure | Heat buildup or water ingress. | Ensure the fixture isn't covered in insulation; check silicone sealing. |
| Photocell Failure | Sensor blocked or faulty. | Clean the sensor window; replace the photocell unit. |
Conclusion
InstallingWall Pack Lightson brick facades requires patience and the right masonry tools, but the result is a significant upgrade to your property's security and aesthetics. By choosing high-quality LED fixtures and following proper waterproofing techniques, you ensure years of maintenance-free operation.
Whether you are illuminating a warehouse perimeter or a storefront entrance, proper installation ensures your lighting investment performs at its peak efficiency.
