LM-79 Testing in Dubai: Key Requirements for Lighting Manufacturers and Suppliers | +971 554747210

 Dubai's lighting industry is expanding at a remarkable pace, driven by massive infrastructure projects, smart city initiatives, and stringent sustainability regulations. As LED lighting becomes the preferred choice for residential, commercial, and industrial applications, ensuring that lighting products meet high-quality and performance standards is more important than ever. One of the most critical compliance requirements for LED lighting in Dubai is LM-79 Testing.

LM-79 Testing is a globally recognized evaluation method that assesses the photometric and electrical performance of LED lighting products. For lighting manufacturers and suppliers operating in Dubai or exporting to the UAE market, LM-79 testing is essential for regulatory approval, market acceptance, and long-term brand credibility.

In this blog, we break down the key LM-79 testing requirements in Dubai, explain the importance of compliance, and highlight how manufacturers and suppliers can ensure their products meet UAE standards.


Understanding LM-79 Testing

LM-79 is a standardized testing procedure developed by the Illuminating Engineering Society (IES). It focuses on evaluating the absolute performance of LED products, ensuring accurate and repeatable results.

LM-79 testing covers:

  • Luminous flux (lumens)

  • Luminous efficacy (lm/W)

  • Color rendering index (CRI)

  • Correlated color temperature (CCT)

  • Chromaticity coordinates

  • Electrical characteristics

  • Light distribution patterns

These parameters help determine whether an LED product meets the performance claims stated by manufacturers and whether it complies with Dubai’s efficiency and safety regulations.


Why LM-79 Testing Is Important in Dubai

Dubai is known for its strict compliance standards in lighting, particularly because the emirate prioritizes:

  • Energy efficiency

  • Environmental sustainability

  • Safety

  • High-performance infrastructure

LM-79 tests help ensure lighting products meet these requirements and support Dubai’s long-term goals for sustainable urban development.

Key reasons LM-79 testing is essential:

  1. Mandatory for product approvals and certifications

  2. Required for major construction and smart city lighting projects

  3. Ensures accurate performance evaluation in Dubai’s harsh climate

  4. Builds trust with project consultants, contractors, and developers

For manufacturers and suppliers, LM-79 compliance is not optional—it is a critical benchmark for market entry.


Key LM-79 Testing Requirements for Lighting Manufacturers and Suppliers in Dubai

To successfully introduce LED lighting products into the Dubai market, manufacturers and suppliers must meet specific LM-79 testing requirements. These cover documentation, testing procedures, quality standards, and regulatory guidelines.

Below are the most important requirements to understand.


1. Testing Must Be Performed by an ISO/IEC 17025 Accredited Laboratory

Dubai authorities, consultants, and major project developers require LM-79 results from accredited laboratories only. An ISO/IEC 17025 accreditation ensures the lab follows internationally recognized testing and calibration standards.

Accredited labs provide:

  • Accurate measurement conditions

  • Calibrated testing equipment

  • Reliable and accepted test reports

Using non-accredited lab reports can lead to rejection during product approval or vendor qualification processes.


2. Complete Photometric and Electrical Evaluation Is Mandatory

Dubai clients expect comprehensive LM-79 testing that includes all major parameters. Manufacturers must ensure their products are tested for:

  • Total luminous flux

  • Luminous efficacy

  • CRI and CCT

  • Chromaticity stability

  • Beam angle and distribution curves

  • Power consumption and power factor

These results are essential for lighting design calculations and energy modelling.


3. Test Reports Must Include Detailed Test Conditions

Dubai’s regulatory bodies and construction consultants require full transparency in test reporting.

A standard LM-79 report must include:

  • Model and product specifications

  • Ambient temperature

  • Test equipment details

  • Measurement instruments

  • Distance and setup used

  • Current and voltage readings

This ensures test results can be validated and replicated when needed.


4. LED Drivers Must Also Meet Performance Standards

Dubai requires not only the LED fixtures but also the LED drivers to meet specific performance metrics. LM-79 testing should include:

  • Driver efficiency

  • Flicker performance

  • THD (Total Harmonic Distortion)

  • Stability under voltage fluctuations

Poor-quality drivers can lead to flickering, failures, or safety hazards, making driver performance testing essential.


5. Temperature and Thermal Behavior Should Be Reported

High ambient temperatures in Dubai make thermal performance a critical factor. LM-79 testing must document:

  • Operating temperature

  • Thermal stability

  • Impact on luminous output

  • Stability of color performance over time

Products that perform well in cooler climates may fail in Dubai if not properly engineered.


6. Light Distribution Data Must Be Provided for Project Approvals

Consultants and engineers often request goniophotometer data to verify:

  • Beam angle

  • Light spread

  • Distribution uniformity

This data is crucial for lighting simulations, roadway lighting, and architectural designs.


7. Compliance With UAE.S and Dubai Municipality Requirements

Many lighting products must also meet local standards such as:

  • UAE.S 5010-1 (energy efficiency for lighting products)

  • Dubai Green Building Regulations

  • DEWA efficiency guidelines

LM-79 testing helps demonstrate compliance with these regional regulations.


8. Products Must Pass LM-79 Testing Before Large Project Tenders

Developers and contractors typically require LM-79 test reports before:

  • Vendor registration

  • Material submittal approvals

  • Technical evaluations

  • Final project acceptance

Without valid LM-79 test reports, suppliers may lose opportunities in major projects.


9. Test Reports Must Be Recent

Dubai’s consultants often require LM-79 reports that are not older than 2 years. This ensures:

  • Current manufacturing batches match tested samples

  • No changes occurred in LED sources or drivers

  • Product performance remains consistent

Outdated reports are often rejected.


10. Products Must Match the Exact Model Tested

The product supplied for a project must match the one tested in the LM-79 report. Manufacturers must ensure:

  • Same LED chips

  • Same driver model

  • Same housing and optical components

Any changes may result in re-testing.


Benefits of LM-79 Testing for Manufacturers and Suppliers

LM-79 testing is not just a compliance requirement—it offers significant business advantages:

✔ Increases acceptance rate in large Dubai projects

✔ Demonstrates product reliability and quality

✔ Enhances brand credibility in the UAE lighting market

✔ Supports sustainability and energy-efficiency goals

✔ Helps align with green building certification requirements

Investing in LM-79 testing improves long-term competitiveness and opens doors to major tenders.


Conclusion

LM-79 Testing is a crucial requirement for lighting manufacturers and suppliers looking to enter or expand within the Dubai market. With strict local regulations, high demand for sustainable lighting, and fast-paced infrastructure development, LM-79 compliance has become a core part of product certification and approval.

By ensuring products are tested in accredited laboratories, providing complete photometric and electrical data, and meeting UAE-specific requirements, lighting companies can position themselves as trusted partners in Dubai’s growing lighting industry.
