Quality Control Built Into Every Step
From raw material inspection to final shipment, our multi-stage quality control system ensures every Upward Lighting product meets consistent performance standards -- batch after batch, order after order.
Three-Stage Inspection System
Every product passes through three critical checkpoints before reaching your hands.
Incoming Material Inspection
All raw materials and components -- LED chips, drivers, housings, lenses, and hardware -- are inspected upon arrival before entering the production floor.
-
LED chip luminous flux & color consistency
-
Driver input/output voltage & efficiency check
-
Housing dimensional tolerance verification
-
Supplier certificate of conformance review
-
Non-conforming materials quarantined & returned
In-Process Inspection
Quality checkpoints are embedded throughout the production line. Operators and QC staff conduct real-time monitoring at each assembly station.
-
PCB soldering quality & connection integrity
-
Optical assembly alignment & beam angle check
-
Sealing & gasket installation verification
-
First-article inspection at each production shift
-
Defect tagging & immediate rework protocol
Finished Goods Inspection
Before packaging and shipment, every finished unit undergoes comprehensive functional, electrical, and appearance testing to confirm it meets specification.
-
100% power-on functional test
-
Lumen output & CCT measurement
-
IP rating water ingress test (sampling)
-
Appearance & cosmetic defect review
-
Label, packaging & accessory completeness
100% Burn-In Aging Test Before Every Shipment
Unlike factories that skip aging tests to cut costs, Upward Lighting subjects every single unit to a continuous 24-48 hour powered aging test. This eliminates early-failure units and verifies long-term luminous flux stability and electrical performance -- so your clients receive lights that work reliably from day one.
AQL-Based Sampling Process
Our sampling inspection follows internationally recognized AQL (Acceptable Quality Level) standards, ensuring statistically valid quality assessment for every production batch.
Professional Test Equipment
Our in-house QC lab is equipped with professional instruments to measure and verify every key performance parameter objectively.
Dedicated QC Team
Behind every certified shipment stands a team of specialists. Our QC professionals bring decades of combined experience to safeguard every LED lighting product we manufacture.
Incoming Inspector
IQC Department
Verifies all incoming raw materials -- LED chips, drivers, housings -- against approved specs before any production release.
Process QC Engineer
IPQC Department
Patrols the production line at defined intervals, performs first-article inspections, and flags deviations before they escalate.
Outgoing QC Inspector
OQC Department
Executes final AQL sampling, validates 24-48 h aging test results, and issues the pre-shipment approval before every export.
QC Manager
Quality Management
Owns the end-to-end quality system, drives CAPA and 8D corrective actions, and leads continuous improvement across all departments.
Quality Records & Traceability
Every production batch is fully documented. Records are retained for a minimum of 3 years, enabling complete traceability from raw material lot to shipped order.
Issue Tracking & CAPA System
When quality issues arise -- whether detected internally or reported by clients -- our structured Corrective and Preventive Action (CAPA) process ensures they are resolved and never repeated.
Certifications & Compliance
Our products meet the safety, environmental, and regulatory requirements of major international markets.
