I'd measure the voltage at the bulbs on load.

ISTR reading somewhere (maybe in the original fitting instructions?)
that you can't do that simply with these LV transformers for some

Slow starting has actually been found to add very little to bulb life,
so thats not likely to be a factor.

Slow starting adds little to conventional bulb life, but it can double
halogen bulb life.

Well I'm after a 10-fold increase, but even x2 would be nice!: I'll
check what I've got.
