- Vaccine refrigerators, pharmacy cold storage, laboratory and medical display cabinets
- Environment: controlled low temperature; high duty cycles; condensation/defrost risks
- Lighting positions: internal shelves, vertical mullion, door frame, canopy
- Power: 24V/48V DC; harness-based installation with traceability
- Controls: on/off, door switch, controller integration as required
- Not a fit for washdown environments unless specified and validated
- Goal: stable illumination with low early-failure risk and audit-friendly documentation.
- Risks addressed: condensation ingress, corrosion, voltage drop, and uncontrolled changes across production.
- Deliverables: reliability/traceability pack (lot/ECN records), validation plan, and standardized harness BOM.
- Cabinet layout and shelf configuration; wiring routes
- Operating temperature range and condensation/defrost profile
- Brightness, uniformity, CCT/CRI, and color tolerance expectations
- Power/control method and driver/controller location
- Audit/document requirements (traceability, change control, records retention)
- Sample plan and annual volume estimate
- Early failures under condensation/defrost cycles
- Intermittent faults caused by corrosion at contacts
- Brightness drop on long runs affecting internal visibility
- Inconsistent performance between batches due to uncontrolled changes
- Audit requests for records that suppliers cannot provide quickly
- Moisture control: sealing strategy at end/cable entry; protect joints; avoid capillary leak paths
- Corrosion control: material/finish choice for contacts; protective measures; QC checks
- Power planning: voltage-drop budgeting and injection strategy; connector temp rise control
- Traceability: lot/labeling rules; incoming inspection records; production records per batch
- Change control: ECN/PCN workflow; approved materials list; version control for labels/specs
- Validation discipline: project-specific test plan and summary for customer review
- Condensation/defrost cycling | Condition: project-defined | Pass: no ingress; stable output
- Color/brightness stability | Condition: aging/burn-in | Pass: stable output within spec
- Uniformity at max run | Condition: worst-case shelves | Pass: within agreed tolerance
- Connector temp rise | Condition: max load | Pass: within safe limit
- Record audit drill | Condition: document request | Pass: complete pack retrievable within agreed time
