Sengled is an active Chinese smart-lighting and IoT maker based in the Shanghai/Jiaxing area of China, making smart LED bulbs, Zigbee/Bluetooth-mesh/Wi-Fi lighting, smart plugs, and some cameras and sensors. It has no own-name IEEE OUI — a confirmed finding against the IEEE-derived registry, not a pending check. Because Sengled registers no MAC prefixes of its own, its devices surface under their radio/chipset vendors rather than under a Sengled block. The key analyst angle is Zigbee versus Wi-Fi: many Sengled bulbs are Zigbee and connect through a hub rather than directly over IP (so they expose no directly visible IP-side MAC), while Wi-Fi bulbs surface directly, typically under a Wi-Fi chipset vendor's OUI such as Espressif or Telink. A Sengled support note reportedly says Wi-Fi bulb MACs begin with "B0," but that is a third-party vendor note, not an IEEE registry confirmation. For triage, expect Sengled Wi-Fi devices under a chipset OUI and Zigbee devices only via the hub; there is no Sengled-registered OUI to match against.
- IEEE assignment
- no own-name IEEE registrant (confirmed negative against the IEEE-derived registry); Sengled registers no MAC prefixes of its own [Confirmed] — IEEE oui/mam/oui36 (no Sengled registrant)
- Registry / block size
- none — no own-name block (confirmed negative) [Confirmed] — IEEE-derived registry
- HQ / country
- Shanghai/Jiaxing area, China [Likely] — corporate
- Company status
- active [Likely] — sengled.com
- Device types
- smart LED bulbs, smart lighting, Zigbee/BT-mesh/Wi-Fi lighting, smart plugs, some cameras/sensors [Confirmed] — sengled.com
- Notable products
- smart LED bulbs, smart plugs, smart lighting
- Verified prefix
- none — no own-name OUI (confirmed negative). A Sengled support doc reportedly notes Wi-Fi bulb MACs starting "B0" — third-party (Sengled support), NOT an IEEE registry confirmation [non-IEEE]
- Special note
- The "OUI = brand" model does NOT apply — Sengled has no own-name IEEE OUI (confirmed negative). Devices surface under their radio/chipset vendors. Many Sengled bulbs are Zigbee (connect via a hub, not directly IP); Wi-Fi bulbs surface directly, under a Wi-Fi chipset vendor's OUI (Espressif/Telink). The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- Espressif, Telink (likely chipset suppliers)
- Analyst note
- Expect Sengled Wi-Fi bulbs to often appear under a chipset OUI; Zigbee bulbs appear only via the hub. There is no Sengled-registered OUI to match against.
