Recommended wifi light bar or led - UK?

Does anyone have a recommended brand of wifi light bars or leds? Ideally this would plug and play, both in the physical fitting and in HA.

I want to use it to imitate fire light flicker, so would ideally have a routine I could trigger on the bulb itself. Previously I have used a Hue Lightbar, but with HA firing changes every second to imitate the ‘flicker’ it brings the hue zigbee network to a crawl.
