Commercial LED Wall Pack Lights Buying Guide: Cutoff Types, Forward Throw, Glare Control, and Dark-Sky Compliance
Commercial LED wall packs are specified for perimeter zones where forward throw, cutoff control, and mounting geometry determine coverage quality, glare risk, and boundary spill. Selection begins with the distribution and cutoff classification, then validates mounting height, spacing, and site constraints such as property-line exposure, approach sightlines, and any local restrictions on uplight, glare, and color temperature.
These fixtures are commonly used to replace legacy MH and HPS wall-mounted systems on building perimeters, loading approaches, service corridors, and back-of-house drives where consistent exterior illumination and predictable maintenance intervals are required.

Wall pack spec workflow: cutoff selection, forward throw checks, and documentation routing
Use this workflow to select wall packs by cutoff classification, mounting height, and forward throw requirements, then confirm glare and light-trespass constraints before commissioning. The sections below reflect decision points used in perimeter specifications, including documentation routing for photometrics, submittals, shipping visibility, and closeout.
Wall pack lighting specification guidance
Wall pack performance depends on mounting height, cutoff classification, forward throw distance, glare control, and surrounding site conditions. Incorrect selection commonly results in boundary spill, harsh glare at driver or pedestrian eye level, uneven facade coverage, or ordinance exposure.
For broader exterior strategy across pole-mounted and structure-mounted systems, reference the commercial site lighting buying guide. When perimeter coverage must coordinate with pole lighting to prevent brightness discontinuities across parking rows and drives, align spacing assumptions with the area lights buying guide. For targeted security zones such as docks, laydown yards, and service entrances where aiming geometry determines usable light, use the flood lights buying guide.
Typical failure modes are driven by optic mismatch, unverified forward reach, and placement that puts peak intensity into approach sightlines.
Technical selection guide for commercial LED wall packs
Wall packs are selected for perimeter zones where forward throw, cutoff control, and mounting geometry determine whether coverage supports the target plane or creates glare and trespass issues. Use the sections below to align optic type, mounting height, and layout spacing with site constraints.
Cutoff types and selection rules
Cutoff classification defines high-angle brightness and whether the distribution is optimized for maximum forward throw or controlled downlight. Cutoff selection drives glare risk, trespass risk, and ordinance exposure.
Selection rule: specify traditional wall packs where maximum forward throw is required and boundary exposure is low. Specify full cutoff wall packs where glare control, boundary containment, BUG limitations, or Dark Sky policies apply.
| Wall pack type | What it prioritizes | Best-fit locations | Primary risk | Spec check |
|---|---|---|---|---|
| Traditional (non-cutoff) | Maximum forward throw and broad perimeter brightness | Loading areas, alleyways, back-of-house drives, open perimeters | Glare and spill light near property lines or pedestrian approaches | Confirm ordinance exposure and neighbor viewpoints |
| Full cutoff | Downlight control for reduced glare and reduced trespass | Sites near property lines, residential adjacency, ordinance zones | Under-lighting if spacing is too wide or output is undersized | Validate forward throw distance and spacing using photometrics when constraints exist |
| Selectable / configurable | Standardization with tunable output and CCT | Facilities with mixed constraints across buildings | Inconsistent settings create mismatch across zones | Document final settings by zone at closeout |
Mounting height and forward throw checks
Mounting height changes both forward reach and direct-view brightness at typical approach angles. Lower mounting increases glare risk at pedestrian sightlines and reduces throw. Higher mounting can increase boundary exposure if the distribution is not contained.
| Condition | What happens | Spec fix | Photometric validation trigger |
|---|---|---|---|
| Mounted too low | Short throw and increased glare | Increase height or use full cutoff optics | Validate near entries and walk paths |
| Mounted too high | Increased spill and window exposure risk | Use full cutoff optics and refine spacing | Required when property line constraints exist |
| Forward throw must reach drive lane | Edge zones go dark if distribution is too tight | Select distribution for required reach | Validate at corners and dock approaches |
| Facade hot spots | Bright pools with dark gaps | Adjust spacing and output | Validate when uniformity is required |
Glare and light-trespass control
Wall-mounted fixtures create glare when peak intensity lands in approach sightlines and boundary spill when the distribution is not contained. Cutoff optics, mounting height, and spacing work together to keep light on target planes.
Controls and operating strategy
Perimeter wall packs commonly run dusk-to-dawn. Where policy allows, scheduled reductions and bi-level operation can reduce energy use while maintaining a visible baseline.
Durability and exposure conditions
Outdoor wall packs should be selected for sealing integrity, corrosion resistance where required, and impact resilience in traffic areas. Housing integrity and environmental exposure drive long-term driver survival and service intervals.
FAQs
How do I choose between traditional and full-cutoff wall packs?
Start with the site constraint, not the lumen number. Use traditional wall packs when maximum forward throw is required and there are no practical boundary or glare restrictions. Use full-cutoff wall packs when driver-eye glare, neighbor window exposure, property-line spill, BUG limits, or dark-sky policies apply.
What mounting height should I use for wall packs?
Mounting height is determined by the target plane and the required forward throw. Lower mounting heights increase direct-view brightness at pedestrian sightlines and can create hot spots at doors and walk paths.
What causes glare complaints with wall-mounted exterior lighting?
Glare complaints typically occur when peak intensity is visible from common approach angles such as drive lanes, walk paths, and entry lines.
When should I specify 3000K for wall packs?
Specify 3000K when local ordinances, dark-sky requirements, or residential adjacency limits higher CCT exterior lighting.
Do wall packs need photocells or controls?
Perimeter wall packs are commonly controlled dusk-to-dawn to eliminate daytime burn hours and keep operation consistent.
