Do you mean like these:

So what is needed is a means of efficiently powering them from the
mains, that avoids the high power consumption and failure of the old
10W halogens.

I'm considering such tricks as powering them from 3 AAA rechargables
and charging them via a timeswitch or an electronic substitute so
that they charge only (say) 10% of the day (which surely should be
enough) to save energy. Given the heat losses in "Wall Wart" type
transformers.

Any better ideas from the panel ?


Find a suitable 4.5V or 5V adapter (surely you have a box of those
somewhere). Old phone chargers etc, just find one that's the right
voltage, rated at 60mA or more, and you're away.
