The Victorian Employers' Chamber of Commerce and Industry (VECCI) and Carbon Compass ran a series of webinars on lighting in January/February 2014.

Below are links to the recordings of the sessions. Or you can download just the presentation.

The webinars provided a really good introduction to lighting and lighting technologies. The sessions talk about lighting terminology and the process involved in changing your current lighting to something more efficient. 

Great for those who don't know if you can update to LEDs or whether T5s are the way to go...

Carbon Compass also provide an excellent Resources Page.
