Due to legislation introduced by Turnbull during the John Howard years the the sale of incandescent bulbs is prohibited as of today. More accurately the ban prohibits the sale of light bulbs with an efficacy of less than 15 lumens per watt (lm/W). I checked at the local supermarket and the shelf where the incandescent bulbs used to be was empty. Technological advances were going to see the incandescent replaced over time anyway. I suspect that the compact fluorescent bulbs that I have throughout my house will also be dated technology within a decade as long life LEDs drop in price. Conceivably we will see the day when light bulbs last nearly as long as the house.
The ban isn’t unique to Australia. The EU will see them banned by 2012 and the USA by 2014. Even so this law would have been a really good law to slap a sunset clause on.
