The LED wall pack is the most widely installed commercial outdoor luminaire type — present on virtually every commercial building, parking structure, warehouse, and industrial facility worldwide. As an SKD housing component, the wall pack housing is the thermal and structural foundation that determines IP protection reliability, LED junction temperature, optical distribution, and 25-year outdoor service life.
For lighting manufacturers specifying wall pack housing components and procurement teams sourcing commercial perimeter lighting, this guide covers everything needed — from wattage selection and IP rating requirements to full-cutoff optics, PIR sensor integration, coastal specifications, and sourcing from Anerhui. For related guides see our waterproof LED housing IP rating guide, heat dissipation LED housing guide, and LED housing SKD kit guide.
1. What Is an LED Wall Pack Housing?
An LED wall pack housing is a die-cast aluminum luminaire enclosure designed for direct wall-mounting on the exterior of commercial buildings. It delivers security, safety, and wayfinding illumination for building perimeters, parking lot entrances, loading docks, stairwells, and pathways.
Wall pack housings are supplied as SKD kits — the lighting manufacturer installs their own LED module, driver, and wiring harness. The housing provides the thermal management, IP protection, optical mounting surface, and structural support. The buyer controls LED efficacy, color temperature, driver efficiency, and control protocol independently.
The wall-mounting orientation creates a unique thermal engineering challenge not present in pendant-mount or pole-mount fixtures: the mounting surface blocks the rear fin area entirely, concentrating all convective heat dissipation on the forward-facing fins. Anerhui’s wall pack housings address this through a forward-facing vertical fin array with optimized fin height and pitch, validated by CFD thermal simulation at worst-case 45°C ambient for each wattage variant.
2. Wattage Selection by Application
| Application | Mounting Height | Target Illuminance | Recommended Wattage |
|---|---|---|---|
| Building entrance / lobby | 3–4 m | 50–100 lux | 20W–30W |
| Pedestrian pathway | 3–5 m | 30–50 lux | 20W–40W |
| Parking lot perimeter | 4–6 m | 50–100 lux | 40W–60W |
| Loading dock / service area | 4–6 m | 100–200 lux | 60W–80W |
| Security / large perimeter | 5–7 m | 50–100 lux | 80W–120W |
| Parking structure wall | 3–5 m | 50–150 lux | 40W–80W |
Note: These figures assume LED module efficacy of 140–160 lm/W and a maintenance factor of 0.8. Always verify with a photometric calculation using actual IES files from your LED module supplier before finalizing fixture count and spacing.
3. Full-Cutoff vs Standard Optics
The choice between full-cutoff and standard optic wall pack housings has become one of the most consequential specification decisions in commercial outdoor lighting, driven by increasingly strict municipal lighting ordinances and green building certification requirements.
Full-Cutoff Wall Pack Housing
A full-cutoff wall pack uses a flat tempered glass lens positioned flush with the housing face, directing all light output downward and forward with zero upward emission. Benefits include:
- Zero upward light spill — eliminates glow visible from upper floors of adjacent buildings
- IDA (International Dark-Sky Association) compliant — required for dark sky ordinance compliance in many municipalities
- LEED credit eligible — contributes to SS Light Pollution Reduction credit
- Reduced glare for building occupants and neighboring properties
Standard (Non-Cutoff) Wall Pack Housing
Standard wall packs with convex or semi-cutoff lenses distribute some light above the horizontal plane, providing broader illumination coverage but contributing to light pollution. Appropriate for:
- Rural or industrial locations with no light pollution ordinance requirements
- Applications requiring upward illumination of building facades
- Locations where dark sky compliance is not required
Anerhui’s wall pack housing range includes both full-cutoff flat-glass and standard lens configurations — specify at time of order.
4. Thermal Design for Wall-Mount Applications
Wall-mount thermal management presents a fundamentally different challenge from pendant or pole-mount fixtures. The building wall blocks the rear mounting surface entirely — typically 30–40% of the total housing surface area — eliminating rear-surface convective cooling. All thermal dissipation must occur through the forward-facing fins and exposed housing surfaces.
Forward-Facing Fin Array
Anerhui’s wall pack housings use a forward-facing vertical fin array with fins oriented perpendicular to the mounting surface. This geometry creates vertical natural convection channels that operate effectively in wall-mount orientation, drawing cool air from below and exhausting warm air upward. CFD thermal simulation at 45°C ambient validates junction temperature performance for each wattage variant before production release.
Junction Temperature by Wattage
| Wattage | Ambient Temp | Estimated Tj (ADC12) | L70 Lifetime |
|---|---|---|---|
| 20W | 45°C | 62°C | 90,000+ hrs |
| 40W | 45°C | 70°C | 80,000+ hrs |
| 60W | 45°C | 76°C | 72,000 hrs |
| 80W | 45°C | 80°C | 65,000 hrs |
| 120W | 45°C | 85°C | 55,000 hrs |
For detailed thermal management methodology, see our heat dissipation LED housing guide.
5. IP Rating and Sealing Design
IP65 is the standard minimum for all outdoor commercial wall pack applications. The sealing design of a wall pack housing differs from overhead-mount fixtures because the vertical mounting orientation exposes the lens-to-housing joint directly to rain on the lens face, requiring precise gasket groove geometry and consistent silicone O-ring compression.
Anerhui’s wall pack housings achieve IP65 through:
- Precision-machined gasket groove at ±0.03mm dimensional tolerance on all sealing surfaces
- Silicone O-ring gasket, Shore A 50 durometer, pre-installed in groove
- IP65-rated PG cable gland entry (top or back, per specification)
- Stainless steel A2 locking fasteners maintaining consistent clamping force
- IP65 testing performed on fully assembled housing — with lens, gasket, and cable gland installed
For coastal installations within 5km of the ocean, specify IP66 with e-coat + superdurable powder coat surface treatment. For full IP specification guidance, see our waterproof LED housing guide.
6. Smart Controls: PIR Occupancy Sensing
PIR occupancy control for commercial perimeter wall pack lighting typically achieves 30–50% additional energy savings versus fixed-output LED operation. Parking lot perimeters, service area walls, and building entrance lighting all have variable occupancy patterns that make occupancy-based dimming highly effective.
PIR Integration Options
- Built-in PIR sensor compartment: The wall pack housing casting includes a dedicated sensor compartment at the housing top — the lighting manufacturer installs a PIR module during final assembly. Sensor coverage: 180° horizontal, 12m detection range.
- Zhaga Book 18 socket (larger models): Plug-and-play sensor node compatibility. Compatible PIR, daylight, and Bluetooth Mesh nodes snap in without tools.
- External sensor wiring: Cable gland provisions for connecting to separately mounted PIR or DALI-2 control systems.
Dimming Options
| Control Method | Application | Energy Saving |
|---|---|---|
| 0–10V dimming | Standard dimming, simple installation | 20–40% |
| DALI-2 | Addressable control, energy monitoring | 30–50% |
| PIR occupancy | Unoccupied dim to 20%, full on detection | 30–50% |
| PIR + DALI-2 | Full smart control with occupancy | 40–60% |
7. Conduit Entry Options
Top-Entry Conduit
Conduit enters the housing from the top surface — the most architecturally clean option as conduit runs are hidden behind the building facade. Recommended for new construction where conduit routing can be planned during building design. Standard on all Anerhui wall pack housings.
Back-Entry Conduit
Conduit enters from the rear mounting surface — simplifies retrofit installation where conduit runs are already surface-mounted or embedded in the wall. Available on request — specify at time of order.
Conduit Size Options
Standard: 1/2″ NPT (13mm). 3/4″ NPT (19mm) available on request for larger wire gauge requirements.
8. Surface Finish Options
| Finish | Standard Colors | Application | ASTM B117 |
|---|---|---|---|
| TGIC polyester powder coat | RAL 9005 black, RAL 9003 white, RAL 7035 grey | Standard commercial | 500–800 hrs |
| Superdurable polyester powder coat | Any RAL (MOQ 500 units) | High UV / tropical | 1,000–1,200 hrs |
| E-coat + superdurable powder coat | Any RAL (MOQ 200 units) | Coastal / marine | 1,500+ hrs |
RAL 9005 matte black is the most frequently specified color for commercial wall pack housings — its visual recessive quality allows the housing to blend with dark building elements. For full surface treatment data, see our LED housing surface treatments guide.
