I did find frosted ones, but "apparently" they don't sparkle enough.

I have experienced this 'apparent-ness' when dealing with fridge or oven light bulb replacements.

The only advice I can offer is that you be proactive and replace the bulb before it becomes a team effort or mini-project.

You will find that a lot of standard BC light bulbs above 100W generate quite a lot of heat, even to the point that the plastic in the light fitting starts to go brittle, and the wiring within 50mm of the fitting also starts to cook.

So I suspect it's more of a liability issue here than anything else

Not all bulbs with "eco" in their branding are fluorescents.

And I have yet to find an eco bulb at my supermarket with a similar light output to a 200 watt incandescent.

I haven't seen the 140w Philips halogens in a supermarket. I have one and it is very bright and exceptionally hot. Places like Bunnings should carry them. Some supermarkets do carry the 105w bulbs which should be safer in more fittings.

Three 140w bulbs in the living room are going to use about $140 in electricity per year. It'd pay to replace them with an LED installation once the prices come down.

As for the EE bulbs, I will never buy another one, my experience with them is they are expensive, don't last very long and put out a poor light plus they are not eco friendly to dispose of.

CFLs don't like being turned off and on. They may last over 10,000 hours if they're only turned off and on once per day but once you start turning them on and off several times per day their lifespan can go down to something more like 800 to 2500 hours. Unstable power supplies can kill them quickly too. They are not always more cost effective than halogens and LEDs.

I haven't seen the halogen lights that have been mentioned here. Do they fit into the standard BC fitting?

They're available in screw and bayonet format and every supermarket I know of sells them.

Some didn't last 2 hours, some didn't even go at all, complete waste of money.

It varies a lot by brand. Edapt (cheapies) are pretty bad, Phillips are good. Consumer agrees:

Btw - Phillps also does energy saving halogens around 30% saving over the standard halogen:

At least a couple of the failures were Philips.

The Phillips Tornado's I have have been good. I see they did not fail in the consumer test until somewhere in the 6,000 - 10,000 range. Other Phillips labels did not go so well.

But I totally agree. CFL's do not suit every application.

Technofreak: Try going to somewhere like Mitre 10, they have them.

Yes well the instruction to purchase was for clear twisty candle bulbs. I did find frosted ones, but "apparently" they don't sparkle enough.

I also tried The Lightbulb Man www.lightbulbman.co.nz as they usually have everything, but they are having trouble sourcing them now as well.

Osram make a nice clear halogen bulb in a candle shape (http://www.osram.com.au/osram_au/Indoor_%26_Outdoor_Lighting_Catalog_for_Australia_and_New_Zealand_2009_-_2010/Indoor%26Outdoor_Catalog_PDFs/Chapter_02-HALOGEN_lamps_2009_2010.pdf - "Halogen Energy Saver Classic B) - not twisty, but very sparkly. Have sourced these for a number of chandeliers and when turned on it's difficult to tell the difference from an incandescent. Most specialist lighting stores (e.g. Lighting Direct) often have these in stock.
