Incoming Material Inspection
Glass shells, lamp bases, LED components, filaments, drivers and packaging materials are checked before production release.
Quality Control
Practical QC for specialty bulb orders
AOTENG Lighting uses clear inspection points from incoming materials to pre-shipment sampling, supporting repeat orders, mixed-SKU shipments, replacement bulb matching and OEM / ODM production.
In-Process QC
Key production steps are inspected during assembly to reduce dimensional, structural and process variation.
Electrical Performance Test
Voltage, wattage, current, light output and stability can be checked against confirmed order specifications.
Aging / Burn-in Test
Sampled bulbs are powered at rated conditions to screen early failures, flicker and unstable performance.
Appearance Inspection
Glass finish, color, base alignment, markings and visible defects are checked before packing.
Packaging Inspection
Labels, barcodes, carton marks, mixed-SKU packing and export carton condition are reviewed.
Pre-Shipment Sampling
Finished goods are sampled before shipment release to confirm order consistency and packing readiness.
Report Support on Request
Inspection records, photos and basic test summaries can be prepared on request for qualified orders.
How QC supports buyers
Built for real B2B purchasing scenarios
Repeat Orders
Confirmed samples and specifications help maintain stable supply across recurring purchase cycles.
Mixed-SKU Shipments
Packaging and carton checks reduce confusion when different models ship in one order.
Replacement Bulb Matching
Base, voltage, wattage, glass shape and application details are reviewed before quotation and production.
OEM / ODM Orders
Custom structure, packaging and labeling requirements are checked against the agreed specification.
