| Panel construction | Use a rigid, low-glare LED panel with a metal housing and a suitable optical diffuser. | No sharp accessible edges, loose diffuser, visible deformation, or rattling parts after installation. | Visual inspection, mechanical inspection, and installation instructions. |
| Suspension system | Select adjustable suspension cables, rods, or mounting kits rated for the complete luminaire assembly. | Four-point support is preferred for rectangular panels; the panel must remain level and stable during normal use. | Load rating, anchoring method, ceiling assessment, and completed installation checklist. |
| Ceiling and anchor compatibility | Match anchors and fixings to concrete, steel, timber, or suspended-ceiling construction. | Never rely on ceiling tiles alone to carry the luminaire unless the ceiling system is specifically engineered for that load. | Substrate identification, anchor specification, and site-level structural approval where required. |
| Input voltage and frequency | Choose a driver compatible with the destination country’s nominal voltage and frequency. | Common global configurations include 100–240 V AC, 50/60 Hz, but the product label and driver datasheet must be verified before purchase. | Electrical rating label, driver datasheet, wiring diagram, and local electrical inspection. |
| Electrical protection | Provide protective earthing where the luminaire is Class I and install suitable overcurrent protection. | Protective conductor continuity, secure terminals, strain relief, and no exposed live parts. | Continuity test, insulation test, polarity verification, and electrical installation record. |
| Applicable safety standards | Require conformity documentation relevant to the destination market, such as IEC/EN 60598-1 or equivalent national requirements. | Documentation should identify the exact model, electrical ratings, test scope, and applicable market. | Declaration of conformity, safety test report, risk assessment, and installation manual. |
| Ingress protection | Use an IP rating appropriate to the installation environment. | IP20 is generally intended for dry indoor locations; damp or dusty areas require a product specifically rated for those conditions. | IP marking, test documentation, environmental assessment, and correct sealing of cable entries. |
| Thermal management | Keep the driver and LED housing ventilated and do not cover heat-dissipating surfaces. | No insulation, packaging, or other material should obstruct designed ventilation paths. | Clearance check, operating-temperature data, and inspection for overheating or discoloration. |
| Emergency lighting interface | Where emergency illumination is legally required, use a luminaire and emergency driver designed and tested for that function. | Normal lighting alone must not be treated as emergency lighting without the required emergency equipment and testing. | Emergency duration test, battery or central-supply documentation, and local compliance records. |
| Dimming and controls | Confirm compatibility between the driver, dimming protocol, control wiring, and building-control system. | No flicker, unexpected shutdown, audible noise, or control conflict throughout the dimming range. | Control wiring diagram, commissioning record, and functional test at minimum and maximum settings. |
| Glare and visual comfort | Prefer a diffuser and optical design suitable for the task, viewing angle, and ceiling height. | Check glare risk at normal working positions; UGR data should be used only when calculated for the actual room layout. | Photometric file, lighting calculation, sample-room inspection, and user feedback. |
| Light quality | Specify color temperature, color-rendering performance, and consistency for the intended application. | Typical indoor options are 3000–4000 K; verify the declared color-rendering value and color tolerance in the datasheet. | IES or equivalent photometric file, color data, and incoming-goods sampling inspection. |
| Power efficiency | Compare system efficacy rather than LED-chip efficacy alone. | Calculate lumens per watt using delivered lumens divided by total luminaire input watts, including the driver. | Independent or manufacturer test data, measured input power, and delivered-lumen report. |
| Installation clearance | Maintain the manufacturer’s specified separation from walls, insulation, sprinklers, HVAC equipment, and combustible materials. | The panel, driver, and cables must not interfere with fire-protection, ventilation, access, or building-maintenance systems. | Reflected ceiling plan, site coordination drawing, and final clearance inspection. |
| Cleaning requirement | Clean the diffuser and housing with a soft, dry or slightly damp, lint-free cloth. | Do not use abrasive pads, solvents, high-pressure water, or aggressive chemical cleaners unless expressly approved. | Cleaning procedure, maintenance log, and inspection for yellowing, cracks, or clouding. |
| Routine inspection interval | Inspect suspended fittings, cables, connectors, housing, and light output at least annually in normal indoor use. | Use shorter intervals in high-vibration, dusty, humid, corrosive, or publicly accessible locations. | Dated inspection checklist, defect report, and corrective-action record. |
| Electrical servicing | Isolate and lock out the electrical supply before opening, rewiring, or replacing the driver. | Only qualified personnel should perform electrical work in accordance with local regulations. | Isolation procedure, electrical work permit where required, and post-service testing. |
| Spare parts and serviceability | Prefer replaceable drivers, connectors, suspension components, and diffusers when the design permits. | Replacement parts must match electrical ratings, dimensions, temperature limits, and safety requirements. | Parts list, wiring diagram, service instructions, and documented compatibility information. |
| End-of-life handling | Separate electrical equipment from general waste and follow the destination country’s recycling requirements. | Remove the luminaire safely, protect workers from falling parts, and use authorized waste channels where required. | Product material information, disposal instructions, and waste-transfer documentation. |
