The (possibly surprising) future of incandescent bulbs
Most commercial buildings in Australia have moved away from incandescent bulbs to compact fluorescents, which are much more energy efficient and last longer. The limitations of CFLs are slow warm up time, early failure if frequently switched, and high cost ...

Lifecycle efficiency of LEDS the same as compact fluorescent
Research recently undertaken by Siemens says that the lifecycle efficiency of LED lights is equal to that of compact fluorescents. Measuring the lifecycle efficiency involves looking at the energy to manufacture and dispose of the product, in addition to the energy ...

Is Plasma Light a serious competitor to LED light?
Controlled Plasma (CP) lighting technology is the latest of a number of emerging innovative lighting technologies that inadvertently help reduce GHG emission through energy efficiency. In fact its Melbourne inventor Graeme Huon (formerly and acoustics engineer) asserted that ...
