What to Check When Sourcing
The smart lighting module ecosystem has consolidated around a few chipsets — Silicon Labs EFR32, Nordic nRF52840, and Texas Instruments CC2652. Which chipset matters because it determines firmware update frequency and long-term support.
Matter certification. Matter-certified products must have a CSA-issued device attestation certificate (DAC) burned into the device at the factory. Ask the factory for their CSA vendor ID and verify it in the Matter Product Database. Non-certified products marketed as “Matter compatible” will fail Apple HomeKit setup.
Zigbee coordinator compatibility testing. The Zigbee Alliance certification does not guarantee interoperability with all coordinators. Test sample units against your target hub (Philips Hue Bridge, Amazon Echo, SmartThings) before committing to mass production.
OTA firmware update mechanism. For private-label products, you need control over firmware updates. Clarify whether the factory provides source code access, a white-label firmware service, or only binary OTA files. Binary-only means you cannot fix critical security vulnerabilities independently.
Common Issues
FCC Part 15 Subpart B re-testing after hardware change — If the factory changes the RF module between your approval and production, the FCC authorization on the original module is void. Specify that any component changes require written approval and re-submission.
Color accuracy at <20% dimming — RGB mixing quality degrades at low brightness levels. Test the full dimming range (100% → 1%) against a reference white target before sign-off.
