Saw this 3 weeks ago in IKEA Perth. Only available for screw cap (E27 or 27mm) and not bayonet mount (pin head.. if you know what I mean).
Went today and there are still plenty of stocks. Not sure how good they are but hey… you can get 75cent incandescent bulbs but 20W Energy Saver for less than $2 plus the electricity cost you save… what can you complain.
Not sure when the sales end but it could be the end of June.
