Osram GmbH — 84:18:26 (MA-L)

A MAC address starting 84:18:26 belongs to Osram GmbH, the Munich-based lighting and photonics manufacturer, and is most plausibly seen on networked lighting-control hardware — most likely the LIGHTIFY Wi-Fi-to-ZigBee smart-lighting gateway, though no source ties this exact prefix to a named device model.

Osram GmbH is a long-established German lighting and photonics company founded in 1919, headquartered in Munich, and merged into ams OSRAM AG in 2020. Its OUI-registered address on Marcel Breuer Str. 6 sits in the same Munich postal district as ams-OSRAM's current stated group headquarters, corroborating an active, real-world registrant rather than a shell registration.

IEEE's authoritative registry lists exactly one MA-L block for Osram GmbH: 84:18:26. A second prefix, 7C:B0:3E, appears attributed to "OSRAM GmbH" in a stale local third-party snapshot, but a live lookup shows that block is currently registered to Inventronics GmbH, a separate LED-driver company — it is not part of this entry.

Osram's connected-lighting product line has documented security history: Rapid7 disclosed nine vulnerabilities (CVE-2016-5051 through CVE-2016-5059) in OSRAM SYLVANIA Lightify Home/Pro products in 2016, including a cleartext-stored Wi-Fi password and a weak default gateway pre-shared key. No advisory names the 84:18:26 OUI specifically, so this is product-line-level context rather than device-specific confirmation.

IEEE publishes no registration date for 84:18:26 or any OUI block. A third-party aggregator shows an initial-registration date of 13 July 2014, but that is a database-scrape artifact, not an IEEE fact, and is not recorded here as one.

Analyst note

Single-OUI registrant but clears the vendor-substance bar on identifiable-company grounds — active corporate presence, documented product line, and independently reported security history for its connected-lighting products.
