Smart LED bulb, colour changing

The smart led bulb, colour changing runs on Wi-Fi 2.4GHz, works with Matter over Wi-Fi, chosen for compatibility across the widest range of existing routers and hubs found in UK homes. Internally the unit combines a low power microcontroller with a dedicated sensor or actuator stage, and the housing is moulded from flame retardant polymer that passed the Yiwu laboratory's continuous load heat test without discolouration. Every unit is provisioned in the factory with unique credentials before packing, so setup on arrival is a matter of scanning a QR code rather than entering long device keys by hand.

Bench testing recorded rated 9W, equivalent to 60W incandescent and confirmed 16 million colour output with tunable white from 2700K to 6500K. Latency between an app command and the device responding averaged under 400 milliseconds on a typical home Wi-Fi network, and the unit maintained its connection through three consecutive router reboots without requiring a manual re-pair.

This unit is most often purchased by households replacing hallway and bedroom bulbs with app controlled lighting. It is typically the first smart home device a household buys, which means packaging and the initial setup screen carry as much weight in repeat sales as the hardware itself, and both have been kept deliberately simple.
