I'm again looking into LED lighting for our living area. In my heart I want LED lighting. I am concerned that our contingency will be consumed well before then and we won't be able to afford to install it even though it makes economic sense to do so.
We didn't specify it when seeking quotes because I couldn't find mainstream consumer LED downlights because they are relatively new into the mainstream domestic market. However that seems to be changing, and I'm discovered new online sources of information (for example this this forum article and this one too).
Based upon information in the forum, a Google search found some useful links, including the useful guide to LED lights for existing light fittings at LEDcentral.com.au. The site has an online calculator for the savings that can be accrued from LED lighting compared to halogen downlights; however for new installs it is pretty unlikely anyone would be using halogen downlights these days because they are being phased out. LED lights also seem to have lower output, and more lights may be required for the same illumination. In the calculator, the default electricity price is a little low for our supplier (19.371c/kwh) and as for the whole of Victoria, this will increase significantly every year. The calculator allows the rate to be adjusted.
LED Lighting Australia, Todae and Enviroshop offers similarly priced lights as LEDcentral.com.au. Please note that I haven't purchased product from any of these shops and cannot advise on the quality of their businesses or products. Todae has a good downlights guide that explains the need for transformers for LED lighting, unless they are suitable for 240V (eg GU10 fitting).
A post at the HomeOne forum identified BrightGreen as a supplier of LED lights that are comparable to the common 50W halogen downlights that are being phased out.
As I find out more, I'll keep this post updated.
