Not sure what horror stories you have heard but supply is not too bad in Australia, I see them in stock in retail stores, I have had Lifx for a long time, still going strong.
And at this very moment the dang color bulb is sold out on their website.
I will keep an eye out for a bargain or better bulb if I can find one. I am definitely hoping to be impressed now that I am a lifelong consumer of these things.
