Philips Hue / Signify — registered as "Philips Lighting BV" (MA-L)
Summary
- // what this is
- Philips Lighting is registered to MAC prefix
EC:B5:FAin the IEEE OUI database. When a device's MAC address begins withEC:B5:FA, that block was registered by Philips Lighting — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A Philips Lighting/Signify OUI almost always = a Hue Bridge (typically one per site); the bulbs are Zigbee and invisible at L2/L3, so one OUI hit usually represents an entire lighting deployment.
About this vendor.
Philips Hue's IEEE blocks are registered under the legacy name "Philips Lighting BV" at High Tech Campus 45, Eindhoven, Netherlands — a name that no longer matches current branding, since Philips Lighting was spun off from Royal Philips (IPO 2016) and renamed Signify N.V. effective 16 May 2018. The most important device-identification fact: on the IP network, the only Hue device that appears with a Philips/Signify OUI is the Hue Bridge (the IP-connected hub). The Hue bulbs themselves speak Zigbee behind the bridge and do NOT expose IEEE MAC OUIs at L2/L3, so a single OUI hit typically represents an entire lighting deployment rather than many devices. Some Wi-Fi lighting (e.g., the WiZ brand, acquired 2019) may appear under separate registrants. A normalization caution: distinguish the lighting registrant (Philips Lighting BV / Signify) from the general "Philips" / "Koninklijke Philips" (Royal Philips) registrants used for healthcare and consumer electronics — these are different organizations after the 2016 spinoff. For triage, a Philips Lighting/Signify OUI almost always means a Hue Bridge (usually one per home/site).
