Refoss Smart Light Bulb Alexa b22 Bayonet WiFi Led Bulb 9W with Colour Changing Light, 810LM Dimmable (Warm/Cool) Smart Bulbs Works with Alexa(Echo and Echo Dot), Google Home - 2 Packs

Plugged it in, downloaded the app, connected to WiFi. Asks do you want to connect to Alexa and then opened the Alexa app. Took me a little while to set up a group on the Alexa app as the device I wanted to use it with was originally set up in my sons old house, but after a quick reset I managed it just fine. Add the lightbulb and echo dot to a group and can now turn the light on and off with a simple request. Can also set it to auto come on/turn off at dusk and dawn so if you’re away or working then this would be great for added security. You can change the colours and the brightness, there’s a daylight option and you can have it set to warm white or cool white. This can all be done in either the Alexa app or the Refoss app. Tried to dim the lights with Alexa voice control but it didn’t really work. Only bought the 1 to try but will be updating all the lightbulbs around the house as I have kids and they love turning lights on yet haven’t mastered that the switch turns off too!

Arrived on time. Very easy to install and use. Excellent choice.

Mine worked fine until today when I joined prime , now they just won’t connect to the alexa dot speaker, tried most of the day, but just won’t connect , works fine in the Refoss app tho.

Good light bulb with various color modes, easy to pair with the app. It makes life easier for those who always forget to turn off the light or are lying in bed looking for something and don’t feel like getting up. I recommend it.

Functions very well with no issues.

My biggest issue would probably be the range of colour, as an LED lightbulb I would expect it to match more realistically to the colour wheel in-app. Linked to Google, it does not work very well as a soft wakeup (sunrise) light. Does not work with If This Then That ITTT. But for the price I guess I am happy, when it's connected to wifi and the power is on, it will happily work via the app.

Good quality overall, easy to set up. The support is great, they were able to ship me the spare when one of the bulb developed a fault. Been using for 2+ years now.

The setup of these bulbs was simple, the software at first seemed great and the brightness and colour of the bulbs were fantastic. Quite often before bed we tell google to "turn off all the lights" in the house. For some reason this causes all refoss bulbs currently off to give out one last blinding flash before switching off again. Really annoying if it's the bulb in the bedroom and you're about to sleep. I spoke to support in May 24 and they reverted the firmware on that one bulb which fixed it, but since then no new updates so we're stuck on this old firmware version. I have emailed them again after using the second bulb and seeing the same behaviour. If this won't affect you I would say these are great, but for me if they can't fix this I'll be returning them. edit (Dec 2024): Spoke to refoss support again and still no plan to fix the firmware. I'll be switching these out for something better in the new year.
