| 1 | Lighting Design and Photometry | Road-lighting layout, luminous distribution, uniformity, glare control, and compliance with the project’s lighting class. | Project-specific lighting calculation and luminaire photometric files in IES or LDT format. | Compare calculations using the same road geometry, pole positions, mounting height, surface assumptions, and lighting criteria. |
| 2 | System Efficacy and Power | Delivered luminaire efficacy in lumens per watt, input power, and any dimming or operating profiles. | Product datasheet and test report showing the tested luminaire configuration and measurement conditions. | Compare complete-luminaire performance rather than LED-chip figures alone; ensure the optical, driver, and control configuration matches the quotation. |
| 3 | Ingress Protection | Protection against dust and water for the luminaire enclosure and relevant electrical compartments. | Test report identifying the tested model and rating under IEC 60529. | IP65 indicates dust-tight protection and protection against water jets; IP66 covers powerful water jets. Select the rating for the actual site conditions. |
| 4 | Impact Resistance | Resistance of the housing, lens, and other exposed parts to mechanical impact. | Test report for the relevant luminaire configuration under IEC 62262. | For reference, IK08 corresponds to 5 joules, IK09 to 10 joules, and IK10 to 20 joules. Confirm that the tested parts match the proposed product. |
| 5 | Materials and Corrosion Protection | Housing material, coating system, fasteners, seals, and suitability for coastal, humid, or polluted environments. | Material specifications, coating details, and applicable corrosion-test reports. | Assess the complete assembly and site exposure; a material or coating claim should be supported by documentation relevant to the project. |
| 6 | Driver, Surge, and Electrical Protection | Driver model and operating range, power-factor information, over-temperature protection, and surge-protection arrangement. | Driver datasheet, wiring diagram, and applicable electrical or surge test reports. | Agree on the required surge-protection level and test conditions in the specification; do not compare protection claims without matching test details. |
| 7 | Controls and Dimming | Compatibility with the project’s control method, dimming schedule, photocell, motion sensor, or central management system. | Control-interface specification, wiring diagram, and an operating demonstration or sample test. | Confirm interface compatibility and fail-safe behavior before ordering, especially when integrating with an existing control system. |
| 8 | Lifetime and Warranty | Declared LED and driver lifetime, maintenance assumptions, warranty period, exclusions, and replacement process. | Written warranty terms and lifetime declaration stating the applicable temperature and performance-maintenance conditions. | Compare like-for-like declarations and clarify whether the warranty covers the complete luminaire, labor, shipping, and replacement parts. |
| 9 | Quality Control and Traceability | Incoming-material checks, production testing, final inspection, batch identification, and corrective-action process. | Quality procedures, sample inspection records, production test checklist, and traceability examples. | Ask how the supplier links each delivered batch to its components and inspection records; verify procedures through an audit when appropriate. |
| 10 | Compliance, Delivery, and Commercial Terms | Market-specific certifications, sample and production lead times, minimum order quantity, packaging, spare parts, and delivery terms. | Certificates and declarations relevant to the destination market, plus a written quotation and delivery schedule. | Verify certificates against the exact product model and intended market. Compare quotations using the same quantities, specifications, shipping terms, and warranty scope. |
