SumnerBoy: I just ordered the WIFI starter kit - 2 bulbs, the WIFI bridge and a remote. Total cost (incl. delivery) was just under $NZD90. Figured it was worth a shot just for a play. I already have LEDs throughout my home and each of those were $40 a bulb, so this isn't very different.
Unfortunately all my LEDs are GU10 fittings, so I can only use these changeable ones in my table lamps etc.
I'm keen to know how these go, can you post back when you get them?
