Has anyone heard of LIFX?
Its an LED, multicoloured light which fits right into a standard light socket.
It then connects to you wifi, and can be controlled by mobile app.
I came across it while looking for coloured lights for my sister.
* She sometimes has absence seizures when in the loo, but I discovered that by swapping the globe out, she wouldn't for a week or so. I imagine due to the familiarity, but I'm no neuroscientist xD.
The LIFX globe is great, when researching the alternatives I found it was easily the brightest. Many others are actually really dim, more for features than practical lighting.
It does all the colours, and a wide variety of whites. Also, it can be connected to other smart devices for automation and additional functionality (think flashing blue for emails and the like).
It was very pricy, came to a bit over 100aud, but we can now change the light as required, and can even go back to something more normal for when we have guests, and it's been a complete success
