| Ingress protection | IEC 60529 defines IP ratings. IP65 indicates dust-tight protection and protection against water jets; IP66 indicates protection against more powerful water jets. | Confirm the IP rating applies to the complete assembled luminaire, and request a test report for the exact model and configuration. |
| Impact resistance | IEC 62262 defines IK impact-protection ratings. IK08 corresponds to 5 joules; IK10 corresponds to 20 joules. | Check whether the rating covers the assembled fixture, including its lens or diffuser, rather than only a component. |
| Photometric performance | IES LM-79 describes measurements of the electrical and photometric performance of solid-state lighting products. | Request a model-specific report showing measured input power, luminous flux, efficacy, color characteristics, and test conditions. |
| LED package lifetime evidence | IES LM-80 covers maintenance measurements for LED packages, arrays, and modules; IES TM-21 provides a method for projecting long-term lumen maintenance from test data. | Distinguish LED-source test data and projections from the expected service life of the complete outdoor luminaire. |
| Corrosion resistance | IEC 60068-2-52 specifies cyclic salt-mist testing. Results depend on the test severity, duration, materials, and sample construction. | For coastal or humid sites, request the full test conditions and verify that the tested sample uses the same housing, coating, fasteners, and finish. |
| Electrical safety | IEC 60598-1 sets general requirements and tests for luminaires; applicable product-specific requirements depend on the luminaire design and market. | Check that certificates or reports identify the relevant product model, power supply, wiring configuration, and destination market. |
| Outdoor operating suitability | Operating-temperature limits are product-specific and should be stated in the manufacturer’s technical documentation. | Compare the declared ambient-temperature range with the project climate, and ask how thermal performance was evaluated in the complete fixture. |
| Optical distribution | Beam angle and luminous-intensity distribution are model- and optic-specific photometric characteristics. | Request an IES or equivalent photometric file and verify that the distribution suits the garden paths, planting areas, or other intended application. |
| Quality-control traceability | Inspection records, component specifications, and production-batch identification are practical evidence of manufacturing controls; their availability varies by supplier. | Ask for sample inspection records, incoming-component controls, final-test procedures, and a method for tracing delivered units to a production batch. |
| Warranty and after-sales support | Warranty duration, coverage, exclusions, and remedies are commercial terms set by each supplier, not a universal product standard. | Compare written warranty terms, replacement-part availability, response process, and coverage for drivers, LEDs, finishes, and water ingress. |
| Customization and project support | Available options—such as mounting, finish, optics, controls, and cable entry—are specific to each product and production arrangement. | Confirm options in a model-specific specification, and verify that samples and production units will use the same approved configuration. |
