I've been intrigued by the idea of smart lighting for a while, but have been put off by the fact I couldn't think of a justifiable use case (other than the cool factor of being able to remotely control lights), and the fact that the brightness maxed out at about 60W (most of our house uses 100W or 125W CCFL).  But then I hit upon a useful idea - fitting Hue bulbs in the bedroom of my daughter and programming it to gradually lighten over the course of an hour, simulating sunrise.  She's 2.5 years but wakes like a teenager, and especially with the end of daylight savings making it dark even at 7am, I'm thinking that a sunrise simulator might help make the mornings easier.  It also wouldn't hurt to have that in our bedroom too.

So, the wife is on board and I'm looking at starter kits.  But I wanted to know if there was a better place to buy other than Mitre10/Bunnings/Noel Leeming.  Prices seem reasonably consistent among them, but I don't know if there's a cheaper way to buy.

Also, it looks like the kits are all Edison Screw bases.  We have bayonet fittings throughout out house (I actually thought everyone in NZ had bayonet fittings, so was surprised to see so many ES bases out there), so is it a case of buying invididual bayonet bulbs and a bridge separately, or is it easy enough to replace the bayonet fitting on my light fixtures with an ES fitting?
