Thanks peeps. I like the look of the LIFX bulbs and advantage of not needing a hub?
Most smart home devices that need a hub are Zigbee devices.
A decent Zigbee hub will do all other Zigbee devices across a range of manufacturers.
If you don't already have a Zigbee hub/devices then I wouldn't recommend getting a hub for a single device.
The main benefit of Zigbee is when you use lots of devices. They mesh together to extend range and are very low powered.
I have 2 LIFX WiFi RGB bulbs. I love them.
They never lose their 2.4Ghz connection to my router.
I also have a couple Yeelight WiFi bulbs that work perfectly (Yeelight are owned by Xiaomi).
I watch a guy on YouTube who reviews a lot of smart home devices. He has a few reviews of Lifx bulbs and LED strips.
