Review: Great bulb and great support - Great bulb, works really well with my Alexa smart devices and was easy to install. Has a nice warm colour, some other smart bulbs can be very white but you can change it to a nice warm yellow. I like that it remembers your settings when you turn it on and off, other bulbs I have reset to the brightest setting. I also had an issue with with bulb as my toddler, who is currently obsessed with flicking switches, turned it on and off too many times. I reached out to the customer support and they got back to me promptly with a solution. Although the solution worked and the light is back working, they had also offered me a replacement if I couldn't get it working. Get customer support for a good value bulb!
Review: Nice colour - Size fit. Easy of use and many colours choice

## Questions & Answers

**Q: Do these work on 5ghz wifi?**
A: No. It only works on 2.4ghz . However I have a dual band WiFi and it connected to the 2.4 part with no problem.

**Q: How dim is the dimmest setting? I bought another brand for my child's room and wanted it as dim as a night light but even 1% is too bright.**
A: I am quite happy with the levels of dimming. But I think it's all a matter of perception. May I suggest just getting a night light instead of you want very low levels of dimming.

**Q: What's the furthest distance you can be from the bulb to switch it on from your phone?**
A: To switch the bulb on you need an internet connection. Then using the app or Alexa the bulb can be controlled. So the answer is not distance but having an internet connection.

**Q: Can the app sync with music (ie via the phone microphone)?**
A: There is no option in the app for that
