A typical CFL has an efficiency of about 60 Lumens/W, while a halogen has about 20 Lumens/W So, if you stick with fittings that can take a standard E27 or Bayonet Cap bulb you can use CFL and be OK.

The standard "flood" lights that everyone from bunnings to beacon sell - for lighting the yard (2 x 75 Watt hallogens or those traditional yard floods) - none of them would be subject to (ii); but surely plenty of people still install them. I don't think there is a CFL/Fluro equivalent - not for yard flood lights? Cheers Mark BCA Lighting Rules 2011 - Outdoor Lighting Question 6Nov 30, 2011 5:07 am Hi I have seen both CFL and LED bulbs in PAR38 style (this is the round floodlight globe). The long halogen globe (R7) has no alternative yet. All of the motion sensor lights I have seen also have a daylight sensor (although you can override it). They still sell lots of lights that would prevent your house from meeting the standard, although bulbs are going to become harder to purchase as the import bans and minimum efficiency levels come into effect. The whole problem with the lighting efficiency regime is that is so easily bypassed. Once you occupy your house you can replace all your energy efficient lights with something else if you want. It isn't even clear to me who, if anyone, is going to check that my house complies. From what I understand my builder is going to issue a document stating that the house complies with the BCA. It is possible that the final inspector may run around and count up lighting loads, but I doubt it. I am installing efficient lighting where I can, in the interest of reducing power consumption, not because of CO2, just because of $ - the CO2 reduction comes as a side-effect. I prefer the carrot approach (save $) to the stick (lighting bans).
