In-House Facility
Testing Equipment & Infrastructure
Our Shenzhen facility houses dedicated testing equipment for photometric, electrical, environmental, and safety verification -- enabling us to validate products at every stage of production.
Integrating Sphere Photometer
Measures total luminous flux, luminous efficacy, color temperature (CCT), color rendering index (CRI), and chromaticity coordinates with high precision.
High-Low Temperature Chamber
Simulates extreme operating environments from -40°C to +85°C to evaluate thermal stability, material integrity, and performance under temperature stress.
LED Aging Test Line
Continuous burn-in and accelerated aging racks run products under rated load conditions to screen for early failures and validate long-term lumen maintenance.
IP Ingress Protection Tester
Validates dust and water ingress protection from IP20 through IP68, including submersion and pressure spray tests per IEC 60529 standard protocols.
Electrical Safety Tester
Performs hi-pot (dielectric withstand), insulation resistance, ground continuity, and leakage current tests to verify compliance with international safety standards.
Goniophotometer
Maps full spatial light distribution to generate IES/LDT photometric data files, verifying beam angle accuracy for reflectors, lenses, and optical assemblies.

Process
Quality Control at Every Stage
Our QC process is built into the production workflow -- not added at the end. Each stage has defined checkpoints to catch issues before they reach the next step.
Incoming Material Inspection
LED chips, drivers, housings, and connectors are sampled and verified against specifications before entering production stock.
In-Process Quality Monitoring
Assembly line checkpoints verify soldering quality, wiring correctness, mechanical fit, and component placement at each production stage.
Functional & Performance Testing
Completed units undergo photometric measurement, electrical safety checks, and aging runs before being cleared for packaging.
Outgoing Inspection & Documentation
Final batch inspection with test reports, packing list verification, and compliance documentation prepared before shipment authorization.
