Bunnings is selling a new range of OSRAM Parathom LED light bulbs suitable for both bayonet and edison screw 240v fittings. Very well priced and cheaper than online stores.
$29.90 for 12w looks like a bargain compared to these sites:
Amazon Germany: 28.80 Euros
eBay: AU$54 inc postage.
I purchased the 12 watt, 50 watt incandescent equivalent for $29.90 and it looks much brighter than any 50w light bulb I have seen. Very pleasent warm white light with instant switch on, great colour definition (CRI 90+), and no mercury. Dimmable. 650lm output (but looks like more due to semi directional light output). 25,000 hour estimated life time.
The heatsink at the rear of the bulb does get rather hot so I recommend these for open light fixtures only.
