💡Uniformity is more important than brightness. CPTED research shows that even illumination with 4:1 uniformity is more effective at deterring crime than bright spots with dark gaps. A uniformly lit 2 fc parking lot is safer than one with 10 fc hotspots and 0.1 fc shadows between poles.

⚠️Light trespass liability: Over-lighting or poorly aimed fixtures can create glare that blinds drivers and pedestrians, creating liability. Use full cutoff fixtures with proper aiming to keep light on your property. Many municipalities now enforce light trespass ordinances with fines.

🔒 Perimeter Fencing & Boundary Security
Perimeter security lighting must eliminate shadow zones along fence lines that intruders can exploit. The challenge is covering long, linear distances cost-effectively while maintaining uniform illumination. Traditional HID perimeter lights create harsh bright spots with dark gaps between fixtures, actually helping intruders time movements between pools of light. LED flood lights with adjustable aiming and photocell controls provide continuous coverage at a fraction of the energy cost.
Design Parameters
| Target illuminance | 1–5 fc |
| Min illuminance | 0.5 fc |
| Uniformity | 10:1 (avg:min) |
| Mounting height | 15–25 ft |
| CCT | 4000K–5000K |
| Controls | Photocell dusk-to-dawn + motion boost |

🅿️ Parking Lots & Structures
Parking lots are the #1 location for property crimes in commercial settings. Poor lighting creates concealment opportunities, reduces natural surveillance, and makes CCTV footage unusable. IES RP-20 requires minimum 0.5 fc with 4:1 uniformity for open lots, but security best practices recommend 1–5 fc. Pole-mounted area lights with Type III or IV distributions maximize coverage per fixture while minimizing light trespass onto adjacent properties.
Design Parameters
| Target illuminance | 1–5 fc |
| Min illuminance | 0.5 fc |
| Uniformity | 4:1 (avg:min) |
| Mounting height | 20–35 ft |
| CCT | 4000K (camera-optimized) |
| Controls | Photocell + adaptive dimming (50% midnight–5AM) |
Example Configuration

🏢 Building Exterior & Entries
Building entries are critical transition zones where occupants move between bright interiors and dark exteriors. CPTED principles require sufficient illumination for facial recognition at 25 feet — the distance needed to identify an approaching person. Wall packs at entries, security lights at side doors, and bollards along approach paths create layered security. The "1:4 rule" states entry lighting should be at least 25% of interior lobby luminance to prevent dangerous adaptation delays.
Design Parameters
| Target illuminance | 5–10 fc |
| Min illuminance | 3 fc |
| Uniformity | 3:1 (avg:min) |
| Mounting height | 8–15 ft (wall mount) |
| CCT | 3000K–4000K |
| Controls | Photocell + occupancy boost at side entries |
Example Configuration

🚶 Stairwells & Walkways
Exterior stairwells and walkways are high-risk areas combining fall hazards with security vulnerabilities. ADA requires minimum 1 fc on accessible routes; IBC requires egress illumination. Stairwells need higher levels (5–10 fc) with uniform coverage on treads and risers. Wall-mounted fixtures at 8–10ft intervals on alternating sides eliminate shadows on stair treads. Vandal-resistant polycarbonate lenses are critical — standard glass fixtures are frequently broken in parking structures and exterior stairwells.
Design Parameters
| Target illuminance | 5–10 fc (stairs) / 1–2 fc (walkways) |
| Min illuminance | 2 fc (stairs) / 0.5 fc (walkways) |
| Uniformity | 3:1 (avg:min) |
| Mounting height | 8–10 ft (wall) |
| CCT | 4000K |
| Controls | Always-on with photocell / Motion-boost in low-traffic |

⚡ Critical Infrastructure & Facilities
Critical infrastructure facilities — electrical substations, water treatment plants, data centers, government buildings — face elevated threat levels requiring enhanced security lighting. DHS/CISA guidelines recommend 5–20 fc at controlled perimeters with zero dark spots. Camera-compatible 4000K lighting ensures color-accurate CCTV recording. Emergency backup power for security lighting is often mandated. High-wattage pole-mounted area lights with flood light supplements provide the redundant coverage these facilities demand.
Design Parameters
| Target illuminance | 5–20 fc |
| Min illuminance | 2 fc |
| Uniformity | 3:1 (avg:min) |
| Mounting height | 25–40 ft |
| CCT | 4000K (CCTV optimized) |
| Controls | 24/7 on + emergency generator backup |
