“The combination of high luminous efficiency and reliable product quality made this an excellent solution for our infrastructure project. The completed installation achieved the lighting performance specified during the design stage.”
DEL has supported over 1,625 solar street-lighting projects across 50+ countries.
German engineering, European quality and factory-direct manufacturing for infrastructure projects.
From DIALux design to OEM branding, ODM customization and SKD support—all from one trusted partner.
Not because of the light itself—but because of everything around it.
These are the six project risks we eliminate before they become costly problems.
EN 13201
Free DIALux lighting design with EN 13201, IES and local road-class compliance, complete with calculation reports and IES/LDT files.
BOQ
Incomplete BOQs, inconsistent datasheets and non-compliant technical proposals can put the entire bid at risk.
QUALITY
Low-quality components and unrealistic specifications often result in premature failures and higher maintenance costs.
MULTIPLE SUPPLIERS
Working with multiple suppliers creates coordination issues, unclear responsibilities, inconsistent quality and unnecessary delays.
DELIVERY
Unstable production schedules and fragmented supply chains can delay deliveries, increase costs and disrupt your project schedule.
AUTONOMY
Undersized batteries and solar panels cannot provide reliable lighting through consecutive cloudy or rainy days.
A Sino-German joint venture focused exclusively on solar street lighting for roads, highways and infrastructure projects. German engineering, European-quality manufacturing and proven project experience—all built to help EPC contractors deliver reliable infrastructure projects.

— The DEL story
DEL Illumination Co., Ltd. is a Sino-German joint venture and a member of EL Group, dedicated exclusively to solar street lighting for infrastructure projects. With R&D in Germany, manufacturing in China and experience from more than 1,625 projects across 50+ countries, we bring together German engineering, European quality standards and efficient Chinese manufacturing—all from one trusted partner. DEL helps EPC contractors, engineers and infrastructure developers deliver reliable lighting projects with confidence.
Different applications require different lighting strategies.
We recommend the right product, pole height, spacing and photometric design for every project.
M3–M4
15–30 lx
Designed for consistent road illumination with controlled glare and optimized uniformity, balancing visibility, pole spacing and energy efficiency across urban road networks.
M1–M2
30–50 lx
Engineered for higher-speed traffic with high-output optics, strong longitudinal uniformity and controlled glare across wider roads, longer spans and major traffic routes.
P3–P4
5–15 lx
Optimized for reliable off-grid operation with extended battery autonomy and solar generation sized for remote areas where grid access and maintenance are limited.
C2–C3
20–50 lx
Configured for wide-area visibility, higher mounting heights and demanding operating environments, providing reliable illumination across industrial and logistics facilities.
P2–P4
5–20 lx
Designed around pedestrian visibility and visual comfort, with controlled light distribution and low-glare illumination across parks, pathways and public recreational spaces.
M2–M4
20–40 lx
Engineered around project-specific photometrics, mounting conditions and environmental requirements for reliable lighting across ports, airports, railway facilities and transport hubs.
Six services that go beyond the hardware — most included when you specify DEL, from the first DIALux file to after-sales support.
24 h
Review road conditions, lighting targets and project requirements to define the right solar lighting configuration.
Free
Professional DIALux simulations and photometric calculations to optimize illumination, uniformity and pole spacing.
KEEP THE POLE
Convert existing street lighting to solar while retaining existing poles, reducing civil work, installation time and retrofit costs.
PRIVATE LABEL
Customize logos, packaging, manuals and product labels to build and strengthen your own solar lighting brand.
CUSTOM DESIGN
Customize power, optics, batteries, solar modules and structures around specific project and market requirements.
LOCAL FACTORY
Complete SKD solutions with assembly guidance, technical documentation and component support for local production.
Every product family is backed by complete technical documentation,
photometric reports and internationally recognized certifications for project specification.
