In our bathroom we have 2 halogen wall lights with G9 40W mains

see 200L capsules, so we would get less than half the illumination.
Fortunately I have 5 spares so they should out last me!

I have 6 x 12 V MR16 bulbs in my bathroom, fed via a Dimpull. So far
they haven't made a version of the Dimpull that can handle LEDs.

In the 16 years since they were installed (tempting providence) I
don't think I have changed any bulbs, of which I have a stock, but I
am on my 3rd Dimpull. Its soft start is obviously good for bulb life,
just a shame its own design isn't better.

Extrapolating, I don't think I need to worry.

transformer")

Not quite. It is a dimmable pull-cord which feeds my electronic
transformers.

I doubt the Dimpull contributes much to the long lamp life. I suspect
the lamps would have lasted just as long using a basic on/off pull switch
due to the way those electronic transformers work (5A maximum current
limit taking the 'sting' out of the turn on surge - the real 'killer' of
tungsten filament lamps of any type).
