Why LED Highway Lighting Was Selected
Highway lighting operates across large outdoor areas and requires stable lighting equipment suitable for continuous infrastructure operation.
For the Düsseldorf application, the selected LED Highway Light configuration combined:
High Luminous Efficiency
130 lm/W
The high-efficiency LED configuration was used as part of the energy-efficiency upgrade.
Outdoor Protection
IP66
The fixture enclosure is specified for outdoor highway lighting applications.
Surge Protection
10KV
The fixture configuration includes 10KV surge protection.
Wide Input Voltage
85VAC–305VAC (±20%)
The wide input-voltage range provides flexibility for roadway electrical systems within the specified operating range.
Aluminum Alloy Housing
The lamp body uses aluminum alloy for the outdoor lighting fixture structure.

Project Engineering
Lighting & Circuitry Design
Highway lighting replacement requires more than fixture selection.
The lighting system must be considered together with:
Existing roadway infrastructure
Fixture mounting conditions
Electrical circuits
Lighting positions
Road geometry
Operating requirements
LIKELITE supported the project with lighting and circuitry design according to the confirmed project scope.
DIALux Highway Lighting Layout
DIALux Evo was available as part of the engineering service scope.
Other supported engineering tools included:
LitePro DLX
AutoCAD
AGi32
The purpose of the lighting layout was to evaluate the proposed LED fixture configuration within the project roadway environment.
A final DIALux result should always be based on the actual:
road geometry + mounting height + pole spacing + photometric data + project lighting criteria.
Therefore, project-specific Lux and uniformity values should only be published when supported by the actual calculation report.
Onsite Metering
For Projects requiring field verification, LIKELITE can support:
Onsite Metering
The field assessment can be used to understand existing lighting conditions before or during the retrofit process.
Typical assessment items may include:
Existing illumination
Lighting distribution
Existing fixture condition
Dark areas
Roadway lighting performance
Electrical information
The exact measurement scope depends on the project requirements.
Highway Lighting Upgrade Process
01 — Existing Lighting Assessment
Review the existing highway lighting system, available drawings and fixture information.
02 — Technical Data Collection
Collect relevant information regarding roadway layout, mounting conditions and electrical requirements.
03 — LED Fixture Selection
Select the appropriate LED Highway Light configuration according to project requirements.
04 — Lighting Simulation
Prepare DIALux Evo, LitePro DLX, AutoCAD or AGi32 layouts as required.
05 — Engineering Confirmation
Confirm fixture power, quantity, optical configuration and electrical requirements.
06 — Production
Manufacture the 120W LED Highway Lights according to the confirmed technical specification.
07 — Delivery
Supply the project quantity of:
9,000 sets
08 — Installation
Provide project installation support according to the confirmed project scope.
Energy-Saving Performance
The Düsseldorf highway lighting upgrade reported:
25% Energy-Saving Improvement
This result is associated with the specific project configuration and operating conditions.
Energy performance can vary according to:
Existing fixture wattage
Existing fixture quantity
Replacement wattage
Operating hours
Lighting schedules
Electrical conditions
Control strategy
Actual system load
Therefore, the 25% figure should be treated as a project reference result rather than a universal guaranteed saving rate.
For future highway Projects, LIKELITE can calculate the expected energy consumption based on the customer's existing lighting data and proposed LED configuration.
Compliance & Certification
The project product configuration was specified with:
Final certification documents and applicable standards should be verified against the exact production model and project requirements before procurement.
Project Delivery Capability
A highway project involving thousands of fixtures requires coordinated production and delivery.
For this Düsseldorf reference application:
9,000 Sets
of LED Highway Lights were specified.
The project supply configuration was:
120W + 130 lm/W + IP66 + 10KV Surge Protection
This type of bulk supply is suitable for highway retrofit projects requiring standardized fixture configurations across a large installation area.
Quality & Technical Configuration
The project fixture configuration included:
CREE SMD3030 LED
Aluminum Alloy Body
IP66
10KV Surge Protection
130 lm/W
Ra 80
5000K ±300K
30,000 Hours
85VAC–305VAC (±20%)
The technical configuration should be matched to the actual highway conditions before final production.

What This Project Demonstrates
The Düsseldorf application demonstrates LIKELITE's ability to support large-volume highway lighting upgrades with a standardized LED fixture configuration.
The project evidence chain can be summarized as:
Large-Scale Supply
→ LED Highway Lighting
→ Engineering Design
→ Lighting Simulation
→ Electrical/Circuitry Support
→ Installation
→ Energy-Saving Improvement
For procurement teams and EPC contractors, the key value is not only the fixture itself, but the ability to coordinate the lighting product with the engineering and project delivery requirements.
