Before we begin - I was incredibly excited 2 years ago by LimitlessLED's products, but quickly realised after spending $200 or so on them and the accessories that they were incredibly disappointing, so have been looking for something that is a lot easier, 

I recently purchased a couple Mijia Bedside Lamps from Gearb3st, $200~ incl DHL delivery for two (took 3 days from China)

These have really impressed me, not only because of their quality of warm white (High CRI) and great a large amount of RGB hues available, as well as a pretty well put together echo system (incl fully featured iOS and Android app and full Alexa and Google Home compatiblity).

They also integrate very well into Alexa (eg. Install Yeelight/Mi Home skill on Alexa and you're good), where I have created different scenes and can activate them (Alexa, turn on candles).

They are slightly slower to respond to commands than Hue, but that's being picky.

These Mijia Bedside Lamps seem to be one of the very few 90%+ CRI LED smart bulb available - high CRI basically means that the light itself emits a higher colour spectrum than low CRI bulbs, meaning that colours appear vibrant and more natural - and are easier on the eyes.

My next purchase is going to be a Yeelight Smart LED ceiling light - this is a hardwired light fitting replacement, and offers 90+ CRI, full Alexa integration, and enough output for a 15m square room, this is going to go into my office. 

This will be a gateway drug to the much larger 650mm-in-circumference Yeelight JIAOYUE 650 ceiling light, which would be suitable for my lounge. 

Unfortunately it seems that there are no high CRI e27 or bayonet bulbs available :(
