GE Lighting — 3 prefixes (MA-L)

A MAC address beginning DC:2F:FA, 34:13:43, or 78:6D:EB belongs to GE Lighting, typically seen on Cync-branded smart-home lighting hardware — Wi-Fi and Bluetooth smart bulbs, light strips, plugs, and cameras that integrate with Alexa, Google Home, SmartThings, and Apple Home.

GE Lighting traces to 1911, when General Electric consolidated its lighting businesses under one brand, historically headquartered at Nela Park in East Cleveland, Ohio — the same city recorded as the registrant address for all three OUI assignments. Savant Systems acquired GE Lighting from General Electric on 2020-07-01 for roughly $250 million, a deal described as GE's last consumer business.

GE Lighting/Cync publishes a formal responsible-disclosure program with a PGP-encrypted intake address, claiming routine third-party penetration testing — a vendor self-report, not independently verified. No independent third-party vulnerability research specific to GE Cync surfaced; a widely-cited Malwarebytes smart-bulb vulnerability article concerns TP-Link Tapo and should not be attributed to this vendor.

One data-quality note: maclookup.app displays a "registration date" of November 14, 2019 for 78:6D:EB. IEEE's public OUI registry publishes no assignment or registration dates for any MAC prefix, so that figure is a third-party database artifact rather than an IEEE-sourced fact and should not be presented as one.

IEEE assignment

3 prefixes (DC:2F:FA, 34:13:43, 78:6D:EB) → GE Lighting, registered East Cleveland, OH, US [Confirmed] — IEEE OUI Registry (the IEEE MA-L registry, local snapshot at the IEEE MA-L registry)

Registry / block size

Independent security research

none found specific to GE Cync/GE Lighting [Unknown / not found] — cvedetails.com GE vendor listing checked; a Malwarebytes Aug 2023 smart-bulb-vulnerability article is about TP-Link Tapo, NOT this vendor, and is explicitly ruled out here to avoid misattribution

Third-party date caveat

maclookup.app shows "Registration Date: 14 November 2019" for 78:6D:EB — a database-scrape artifact, not an IEEE-published fact [Confirmed as a data-provenance caveat] — https://maclookup.app/macaddress/786DEB (cited only to document what not to trust as a date source)

Analyst note

three separate MA-L assignments plus a documented, currently operating consumer product line (Cync) support a substantive vendor entry rather than a bare single-OUI shell; no OUI-specific independent security research was found.
