LED Street Light Tender Checklist: 8 Key Specifications to Verify Before Ordering

Selecting the right LED street light manufacturer is an important step in any road lighting project. For contractors, distributors, and municipal procurement teams, purchasing decisions involve much more than comparing wattage and price.

An LED street light may look suitable on paper but fail to meet project requirements because of insufficient lighting uniformity, unsuitable optical distribution, inadequate surge protection, or missing technical documentation.

These issues can lead to tender rejection, installation delays, additional costs, and long-term maintenance problems.

Before placing an order, buyers should carefully review the following eight key LED street light specifications to ensure the proposed products match their project requirements.

1. Luminous Efficacy: Check Real Lumens per Watt

Luminous efficacy, measured in lumens per watt (lm/W), is one of the first specifications buyers should examine.

Higher efficacy means a luminaire can produce more light while consuming less electrical power.

For example, a 100W LED street light rated at 170 lm/W would produce approximately 17,000 lumens under its specified test conditions.

However, high luminous efficacy does not automatically guarantee better road lighting.

Buyers should verify:

• Actual luminaire efficacy rather than LED chip efficacy
• Total luminous flux under rated operating conditions
• Power consumption stated in the test report
• Whether the report matches the proposed product model

Some MIC LED street light configurations have supporting performance test reports around 170 lm/W. Actual efficacy must be confirmed for the selected model and configuration.

For government and infrastructure projects, independent photometric reports can provide valuable evidence of product performance.

2. Optical Distribution: Choose the Right Beam Pattern

The optical design determines how light is distributed across the road surface.

Two LED street lights with identical wattage and luminous flux can produce very different lighting results.

Road width, mounting height, pole spacing, arm length, and luminaire tilt all influence the required optical distribution.

Common roadway optical distributions include Type II, Type III, and Type IV, depending on the project design system.

Buyers should request suitable photometric files and verify:

• Average road illuminance or luminance
• Lighting uniformity
• Glare control
• Pole spacing and mounting height
• Light distribution across traffic lanes and sidewalks

Professional lighting simulation software such as DIALux can help contractors evaluate these factors before purchasing.

3. IP and IK Ratings: Evaluate Outdoor Durability

LED street lights operate outdoors throughout the year, often under demanding environmental conditions.

Dust, heavy rain, humidity, temperature changes, and accidental mechanical impacts can affect long-term reliability.

Two important specifications are:

IP Rating — Ingress Protection

The IP rating indicates protection against solid particles and water.

For example, IP66 provides dust-tight protection and resistance to powerful water jets under the relevant test conditions.

IK Rating — Impact Protection

The IK rating indicates resistance to mechanical impact, which is particularly relevant for public infrastructure and exposed installations.

Before approving a product, contractors should confirm that both ratings meet the project’s technical requirements.

MIC offers IP66-rated LED street light configurations for outdoor applications. The applicable test reports should be checked against the exact model being supplied.

4. Surge Protection: An Important Factor in Road Lighting Reliability

Outdoor LED street lighting systems can be exposed to transient electrical surges caused by lightning activity and power network switching.

Insufficient surge protection may damage LED drivers or other electronic components, increasing maintenance costs.

For this reason, many roadway lighting tenders specify minimum surge withstand requirements.

Important points to check include:

• Standard surge protection level
• Availability of upgraded protection
• Relevant test conditions
• Compatibility with the project electrical system

For MIC’s applicable MSL-F-3 configurations, standard 6kV surge protection and optional 10kV protection can be considered according to project requirements.

Buyers should confirm the final surge protection configuration before ordering, especially for projects in areas with frequent thunderstorms.

5. LED Driver and Electrical Compatibility

The LED driver plays an important role in the electrical performance and reliability of a street lighting system.

Before purchasing, buyers should verify whether the driver is suitable for the local electricity supply and project operating conditions.

Key specifications include:

• Input voltage and frequency
• Power factor and harmonic distortion
• Operating temperature range
• Electrical protection features
• Dimming compatibility
• Driver warranty and replacement options

A product designed for one electrical market may require a different driver configuration for another country.

Contractors should therefore confirm electrical compatibility with the manufacturer rather than assuming all product versions are identical.

6. Smart Lighting Controls: Plan for Future Upgrades

Smart street lighting systems can help municipalities and facility operators manage operating schedules, energy consumption, and maintenance activities.

Depending on the project, suitable control options may include:

• 0-10V dimming
• Photocell-based automatic switching
• Programmable dimming schedules
• NEMA or Zhaga interfaces
• Optional IoT-based lighting management

For projects considering future smart city upgrades, it is important to discuss control compatibility during the procurement stage.

MIC provides configurable control options for selected street lighting products, allowing customers to discuss their control requirements before production.

Not every control feature is included in the standard product configuration, so buyers should confirm the selected options in their technical quotation.

7. Certifications and Test Reports: Verify Tender Compliance

Different countries and infrastructure projects may require different product certifications and technical documentation.

Before selecting a supplier, buyers should carefully review the tender documents and confirm which reports are mandatory.

Commonly requested documents include:

The availability of a certificate is not sufficient by itself. Buyers should verify the covered model, test conditions, validity, and relevance to the tender.

Working with a manufacturer that can provide organized technical documentation can simplify project evaluation and approval.

8. Maintenance, Installation, and Long-Term Cost

For large road lighting projects, the initial luminaire price represents only part of the total investment.

Installation labor, electricity consumption, replacement components, and future maintenance can significantly affect operating costs.

Before finalizing an order, contractors should consider:

• Luminaire weight and mounting compatibility
• Driver accessibility and serviceability
• Availability of replacement components
• Housing and thermal management design
• Warranty coverage
• Expected maintenance requirements

A well-designed LED street light should combine reliable performance with practical installation and service features.

Evaluating these factors helps buyers compare the long-term value of different proposals instead of focusing only on the lowest purchase price.
