Halogen bulbs still blowing

check what voltage is getting to the bulbs (when they are running)

...

Also, I guess you know this, you must not touch the glass envekope of the bulb at all with your fingers ever. If you do, they need to be cleaned with meths. This is because grease from your fingers causes localised heat build up and early bulb failure. TonyB

get a multimeter, set it to an AC range of 20 volts or so, and connect it across the bulb with the bulb still in (a couple of pins can be handy here) turn the lamp on and check the voltage (somewhere around 12 is ideal) Sometimes when transformers fail they can give out substantial extra voltage, before dying completely.

ROFLMAO!!!!

oh dear!

Should I call an ambulance now or wait for the post asking for help?

We could club together for a new multimeter, or start a faq about Repairing Your Multimeter. :))

sorry, my mistake, didn't read transformer LESS

If you have energetic kids like ours, every now and again antics in the kids bedroom (not what you might think!) were causing a vibration in the ceiling and I noticed the bulbs had a tendency to blow when that happened. Quite a few bulbs went until I had words. Of course it might be totally unrelated to your problem.

I've had same problem, 240V halogens costing a fortune a year to replace.

Improved things greatly with softstart units

I had similar problem, both transformer (12V) and transformer-less (240V) bulbs were blowing. Mains voltage too high, if I recall right it was 245V. I fitted an autotransformer to the lighting circuit, 100VA, about 10V reducing voltage.
