Quick answers
- Is the LIFX SuperColor 6" Downlight Retrofit Matter certified?
- Yes. CSA Matter certificate CSA264KTMAT55341-24 covers model DR6C4BUS with software 4.200. The certificate does not establish the firmware on a unit you buy.
- Does the LIFX SuperColor 6" Downlight Retrofit work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA264KTMAT55341-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. Apple’s Matter page lists lights among the accessory types the Home app supports.
- Does the LIFX SuperColor 6" Downlight Retrofit work with Google Home?
- Likely. It is Matter certified (certificate CSA264KTMAT55341-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. Google’s supported-device-types page lists the Extended Color Light type.
- Does the LIFX SuperColor 6" Downlight Retrofit work with Alexa?
- Likely. It is Matter certified (certificate CSA264KTMAT55341-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does.
- Does the LIFX SuperColor 6" Downlight Retrofit work with Samsung SmartThings?
- Likely. It is Matter certified (certificate CSA264KTMAT55341-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named SmartThings on a page we hold. SmartThings adds Matter devices through the SmartThings app and a Matter controller.
- Does the LIFX SuperColor 6" Downlight Retrofit work with Home Assistant?
- Likely. It is Matter certified (certificate CSA264KTMAT55341-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Home Assistant on a page we hold. Home Assistant says: “Adding a new Matter device only works in the Home Assistant Companion app.”
- Does the LIFX SuperColor 6" Downlight Retrofit use Thread or Wi-Fi?
- The sources differ. The CSA ledger records Thread for its certificate CSA264KTMAT55341-24 (software 4.200, read October 19, 2026). LIFX’s product page says “Matter + Wi-Fi: connects straight to your router” (read October 28, 2026), and the CSA’s product listing names Thread, Wi-Fi and Bluetooth. Ask LIFX which network your unit uses before you buy a Thread border router for it.
- Does the LIFX SuperColor 6" Downlight Retrofit need a hub or a Thread border router?
- The CSA ledger and the maker name different networks for this model, so we give no hub verdict here; read the Thread or Wi-Fi answer above for both, with their sources.
- When was the LIFX SuperColor 6" Downlight Retrofit Matter certified?
- The CSA certified it on Aug 27, 2026 (certificate CSA264KTMAT55341-24, software 4.200). That is its certification date, not a retail release date, which MatterCatalog does not state.
- Where can I buy the LIFX SuperColor 6" Downlight Retrofit?
- MatterCatalog has verified store links for it at LIFX. Check the current price, model and pack size at the store.
