Quality Control That Never Compromises
At Upward Lighting, quality is embedded into every stage of production -- from raw material sourcing to final shipment. Our multi-layer QC system ensures every LED downlight, track light, and linear light meets international standards and your exact specifications.
Our QC System at a Glance
Quality Control Flowchart
Every product passes through five rigorous checkpoints before reaching your hands.
Raw Material Arrival
Supplier delivery & documentation review
IQC Inspection
Incoming material testing & approval
In-Process QC
First article + continuous line inspection
Aging Test
24-48 hr burn-in at room/high temp
FQC & Shipment
Final inspection, packaging & dispatch
Raw Material Inspection
Every batch of raw materials -- including LED chips, drivers, housings, and optical components -- undergoes rigorous Incoming Quality Control before entering the production line. This prevents defective materials from ever reaching assembly.
LED Chip Verification
Luminous flux, CCT, and forward voltage tested per batch.
Driver & Power Testing
Input/output voltage, PF, and efficiency validated.
Housing Dimensional Check
Tolerances, surface finish, and material compliance verified.
Supplier Documentation
Certificates, test reports, and RoHS compliance reviewed.
In-Process Quality Control
Quality control staff with 3+ years of experience supervise each production line. First Article Inspection (FAI) is performed before full production begins, and continuous in-process checks catch deviations before they become systemic problems.
First Article Inspection
The first unit from each production run is fully verified against spec before batch assembly proceeds.
Continuous Line Monitoring
Dedicated QC inspectors monitor soldering quality, assembly accuracy, and wiring integrity at defined intervals.
Immediate Deviation Correction
Any out-of-spec units trigger immediate line halt, root cause analysis, and corrective action before production resumes.
Production Records & Traceability
Each batch is documented with date, operator, materials lot, and inspection results for full traceability.
Finished Product Inspection
Before any product leaves our facility, it passes through a comprehensive finished product inspection combining statistical sampling and full-batch checks to guarantee batch-to-batch consistency.
Optical Performance
Luminous flux, color temperature (CCT), color rendering index (CRI), and beam angle measured against approved specifications.
Electrical Safety
Withstand voltage, insulation resistance, leakage current, and power factor testing ensure every unit meets international safety standards.
Appearance & Assembly
Visual inspection for surface defects, dimensional conformance, logo accuracy, and packaging integrity before final boxing.
Statistical Sampling (AQL)
Acceptable Quality Level sampling plans are applied to each production batch, ensuring statistically valid pass/fail decisions.
Functional Lighting Test
Every product is powered on and verified for correct operation, flicker, dimming response, and stable light output before packing.
Packaging Integrity
Inner and outer carton checks ensure products arrive at their destination undamaged, with correct labeling and documentation.
Aging Test Chamber
Our independent aging test chamber runs every product through a minimum 24-hour room-temperature burn-in or 48-hour high-temperature (45°C) aging cycle. This stress-screens early failures and validates luminous flux maintenance rate and long-term lifespan reliability before shipment.
Independent Laboratory Verification
We regularly commission accredited third-party laboratories to conduct reliability and compliance testing. These independent results give our customers objective proof that our products meet international safety, EMC, and environmental standards.
