IN-HOUSE QUALITY CONTROL · FOSHAN FACTORY
6-Step In-House Quality Control for Every Donna Lighting Shipment
Every commercial LED luminaire we manufacture passes through a 6-step in-house quality control process before packaging — photometric testing, appearance inspection, temperature-rise testing, high-temperature endurance, automated aging and 100% final lighting test. No unit ships without completing all six steps.

Photometric Parameter
Testing
CRI, luminous flux and luminous performance testing using calibrated integrating sphere systems. Measures all critical optical parameters to verify the product meets specified values before proceeding to inspection.
EQUIPMENT
1.5m integrating sphere + 0.5m integrating sphere · Color difference analyser · Spectrum analyser
PARAMETERS TESTED
Every batch · 3 units per model
Appearance
Inspection
Full visual and dimensional inspection of every unit: housing surface finish, assembly gaps, paint or anodising quality, lens and diffuser clarity, label and marking placement, and screening for any physical damage from manufacturing or handling.
EQUIPMENT
Visual inspection station · Calibrated measurement tools · Surface finish reference standards
CHECKS PERFORMED
100% of units inspected
Temperature-Rise
Testing
LED solder point temperature, driver operating temperature and housing surface temperature are measured under full-load operating conditions. Applied to all new product designs and repeated whenever a component supplier or production process changes.
EQUIPMENT
Thermal imaging camera · Thermocouple measurement system · Temperature data logger
PARAMETERS TESTED
Newdesigns·After component changes
High-Temperature
Endurance Testing
Units are placed in a 75°C–80°C environmental chamber to simulate long-term high-temperature operating conditions. This accelerated test monitors lumen depreciation, colour shift and driver stability to qualify new product designs for the L70 lifespan claim.

Automatic Aging Line
Testing
Every unit is placed on our automated aging production line for a minimum 4-hour burn-in test under voltage cycling and thermal stress conditions. This step catches early-failure units — the most common source of field failures — before they reach the buyer.
EQUIPMENT
Automated aging line · 500+ simultaneous unit capacity · Voltage cycling and impact simulation
TEST CONDITIONS
100% of units - no exceptions
100% Final
Lighting Test
After aging, every unit is re-lit and tested at the final inspection station immediately before packaging. Any unit that fails to switch on correctly, shows flickering, produces incorrect CCT or fails DALI response is pulled from the line and quarantined for investigation.
EQUIPMENT
Final inspection station · Lumen meters · DALI test controller · CCT spot-check meter
CHECKS PERFORMED
100% of units — before packaging
Testing Equipment & Lab Capability
Our in-house testing laboratory allows us to measure and verify every critical photometric, thermal and electrical parameter without relying on external testing services or third-party labs for production QC.
