COB LED Modules from China: High-CRI OEM Sourcing
1 resources tagged with "Led Modules"
COB (chip-on-board) LED modules from China typically run 10-200W with high color rendering (Ra≥90, premium lines Ra≥95) and tunable CCT, often built on Citizen or Bridgelux dies. The number that actually matters at the bench is LM-80 lumen-maintenance data: ask for the report tied to the exact die and drive current you plan to run, not a generic family sheet. Factory MOQ for a custom CCT/CRI binning usually starts around 500-1,000 modules.
An LED module is the light engine (LED dies on a board plus often a thermal substrate), distinct from the finished fixture. The common pitfall is accepting a higher binning CRI claim without the test current matching your driver, which shifts both CCT and flux in real use.

FAQ
What MOQ should I expect for custom COB LED modules?
Stock CCT/CRI combinations often ship from a few hundred units, but custom binning (e.g. Ra95 at a specific CCT) usually pushes MOQ to 500-1,000 modules per SKU.
How do I verify the CRI and lumen claims?
Request the LM-80 report and an LM-79 photometric file tied to your drive current, then confirm CRI on incoming samples with an integrating sphere or calibrated spectrometer during inspection.
Are Citizen or Bridgelux dies always genuine?
Not automatically. Some factories substitute lower-cost dies after sampling, so check date-code markings and ask for purchase records, or specify a sealed-sample reference for production QC.
