Craig and Richard,

Last December, I installed my first LED direct replacement for a CFL (which
long ago replaced the always failed Incandescent) garden path globe.

I am lobbying Leichhardt Council to run a few LED Lighting Trials and have
been investigating LED Lighting options. I expect when #carbontax does go
through, Lighting replacements - Halogen and CFL should be an area home
compensation should be spent on. An ACCC investigation may be warranted
into the pricing of LED Lamps which I expect will drop rapidly.
