Saw this at Countdown Auckland City (Quay Street). Pretty cheap considering they're normally selling for $25 at countdown/kmart and smart bulbs usually start at $20+
No hub required, works with Alexa/Google.
Have not tried but seems like it's a generic smart bulb that can connect to tuya compatible apps.
Colored bayonet ones 14 buck at Countdown Rolleston, down from 35.
