Engineered LED Highway Lighting for Highways, Expressways and Major Road Networks
LIKELITE provides engineered LED Highway Lighting Solutions for highway contractors, EPC companies, electrical contractors, engineering firms and infrastructure project buyers.
Our highway lighting approach combines luminaire selection, roadway lighting calculation, electrical and circuitry design, onsite metering, photometric simulation, CAD layout and project installation support.
The objective is not simply to replace conventional lamps with LED luminaires.
The objective is to develop a lighting configuration that fits the actual roadway geometry, pole arrangement, electrical system, required lighting performance and project installation conditions.

What Highway Lighting Problems Does the Solution Address?
Projects/">Highway Lighting Projects normally involve more than luminaire selection.
A suitable lighting solution needs to consider:
Existing Lighting Infrastructure
- Existing luminaires
- Existing wattage
- Pole height
- Pole spacing
- Mounting arrangement
- Existing electrical circuits
Road Geometry
- Road width
- Number of lanes
- Median configuration
- Shoulder arrangement
- Curves and intersections
- Elevation changes
Lighting Performance
- Average illuminance
- Uniformity
- Longitudinal uniformity
- Glare considerations
- Lighting distribution
- Required maintenance level
Electrical Conditions
- Input voltage
- Frequency
- Circuit configuration
- Surge protection
- Voltage resistance
- Existing power infrastructure
The final luminaire configuration should therefore be selected after the roadway and project conditions have been evaluated, rather than based only on wattage.
LIKELITE Highway Lighting Solution Process
01 — Project Requirement Review
LIKELITE first reviews the project information provided by the contractor or engineering team.
Typical information includes:
- Project location
- Road classification
- Road width
- Number of lanes
- Pole height
- Pole spacing
- Existing lighting
- Required quantity
- Electrical conditions
- Lighting requirements
- CAD drawings
02 — Onsite Metering
Where required, onsite metering can be used to understand existing lighting conditions.
The assessment may include:
Existing Lux → Existing Power → Existing Pole Layout → Existing Lighting Distribution
This provides a practical reference for the LED upgrade design.
03 — Luminaire Selection
The LED highway luminaire is selected according to the actual application.
The reference configuration for this solution is:
100W LED Highway Light
125 lm/W
IP65
10KV Surge Protection
CREE SMD3030 LED
120° Beam Angle
5000K ±500K
The selected power should not be treated as a universal highway specification.
Final wattage depends on the roadway calculation.
04 — DIALux Evo Roadway Calculation
DIALux Evo can be used to model the actual roadway geometry.
The calculation can evaluate:
- Luminaire positions
- Pole spacing
- Mounting height
- Tilt angle
- Road width
- Lighting distribution
- Illuminance
- Uniformity
The objective is to establish a lighting configuration before large-scale installation.

05 — Litepro DLX / AGi32 Calculation
Depending on the engineering requirements, LIKELITE can support:
Litepro DLX Layout
and
AGi32 Layout
These tools provide alternative calculation workflows for projects requiring different engineering platforms.
The final calculation should be based on the actual project geometry and the selected photometric file.
06 — AutoCAD Engineering Layout
AutoCAD layouts can be prepared for project coordination.
Typical drawings may include:
- Roadway layout
- Pole positions
- Luminaire positions
- Lighting circuits
- Cable routing
- Installation arrangement
This allows the lighting design to be coordinated with the wider highway infrastructure.
07 — Lighting & Circuitry Design
A highway lighting solution must also consider the electrical system.
LIKELITE can support:
Lighting Design
Luminaire positioning and lighting distribution.
Circuitry Design
Lighting circuit and electrical configuration.
Surge Protection
Reference configuration includes 10KV surge protection.
Voltage Resistance
Reference product specification includes 1.5KV voltage resistance.
08 — Installation Support
After the design is approved, installation becomes the next stage.
Installation planning may consider:
- Existing poles
- Mounting compatibility
- Luminaire orientation
- Electrical connections
- Cable connections
- Surge protection
- Installation sequence
- Site access
The actual installation method depends on the project contractor and site conditions.

Service
Warranty: 2 Years
Lifespan: 30,000 hours
Certification Reference: INACAL
Reference Output Calculation
Based on the supplied product specification:
100W × 125 lm/W = approximately 12,500 lm
Therefore, the nominal product output is approximately:
12,500 lm per luminaire
This is a product-level calculation based on the stated luminous efficiency.
It is not a roadway Lux measurement.
Actual roadway illumination depends on:
- Pole height
- Pole spacing
- Road width
- Mounting angle
- Optical distribution
- Road surface
- Installation geometry
- Photometric file
Therefore, final lighting performance should be verified through project-specific photometric calculation.

Highway Lighting Upgrade Strategy
Existing System
The first step is to understand the existing lighting system.
Typical assessment:
Existing Luminaire
→
Existing Wattage
→
Existing Pole Layout
→
Existing Operating Hours
→
Existing Energy Consumption
LED Upgrade
The replacement system can then be evaluated through:
LED Luminaire Selection
→
Photometric Calculation
→
Pole Spacing Optimization
→
Electrical Design
→
Installation Planning
Performance Verification
Where project data is available:
Before Lux
→
After Lux
Before Uniformity
→
After Uniformity
Before Energy Consumption
→
After Energy Consumption
This allows the project team to evaluate the actual result instead of relying only on product specifications.
Energy-Saving Considerations
A highway LED upgrade can reduce energy consumption when the new system achieves the required lighting performance with lower installed power and/or improved operating control.
The actual saving depends on:
- Existing luminaire wattage
- New LED wattage
- Operating hours
- Lighting control
- Existing electrical losses
- Required lighting level
- Maintenance conditions
For the Arequipa reference project, the supplied case data indicates:
20% Reported Energy Saving
