So what's the reason for having a different fitting ?
So you can't fit to a normal bulb holder.
Why wouldn't you want to do that ?

It is an idea aimed at making the user only use energy saving lamps, something to do with building regs.
However the lamps are more expensive than the normal 2 prong energy saving lamps, currently about 10p in tesco.

I thought that would be the reason.
But don't understand why you can't fit a normal 2 pin into a 3 pin holder.
Unless they are offset differently ? or different diameter ?

It would be pointless to be able to fit a normal 2 pin lamp in as you could then put a 100w lamp into it.
The 3 pin ones have the pins at odd angles so only the correct lamp type can be used in the correct orientation, you can make out 2 of the pins on this pic here: http://www.google.co.uk/products/ca...r6Edqm-Aak2omBBA&sa=title&ved=0CAwQ8wIwATgA#p

It was when fillament bulbs where still avaliable, to stop you using them, when you should of been using low energy bulbs, i.e. on new builds.

Just replace the bulb holder with a standard bulb holder, they are around a pound each, and will soon pay for themselves in the money saved in buying overpriced lamps!
Anyone know if those (relatively new) 3 pin lampholders will accept the old 3 pin red lamps that were used for electric fires?
the fire lights I've seen are 2 pin.
There was also a 3 pin version.
Why?
2 brightness settings, or did they double as stop/tail lamps in cars?

My parents bought an electric fire, probably 35+ years ago, and it had three-pin lamp holders for the glow.
The lamps where quite a bit dearer, so my dad swapped the holders for two-pin ones.
I reckon it was just a way of getting you to purchase a particular make at a hiked-up price.
My dad bought a new car on the money he saved on those cheaper lamps

Not three electrical connections - Three locating pins on the side of the shell to fit the bayonet lampholder, like this:
Ah.
Not 100% sure but I think they may have different angled pins. Try googling for B22d/3 and BC3 as they look slightly different to me.
