Its a much larger glass envelope than the MR16's have, and the filament is also running quite a bit cooler in a GU10 which is why they dont have the nicer slightly under 3000k colour of a quality MR16 lamp. - most are in the 2700s like a larger older incandescent.

Also the zigzag filament in the GU10s to get the length needed for 230v makes them have hotspots all over the beam pattern on some of them.

richms:

They don't run the glass hot enough to have the halogen cycle occur reliably which is why they have terrible lifespans compared to 12v mr16's which I know of people with 20+ year old ones that are used every night.

I have experieced the opposite. Often had the the MR16s fail, also the pin connection on them can be very flakey, and they need resitting.

Just started installing my new Philips MR16 LED's.

The ones installed so far are working just great. 'Slightly' dimmer than the halogens they're replacing, but we have 22 of them in the lounge so slightly less brightness isn't really an issue. Our power bills are quite high, this might be part of the reason haha.

During the process of swapping out a few of the old transformers, one of the old philips transformers was suffering burnout, and smelled strongly of like how burned capacitor smell. We've had no end of problems with philips transformers, thankfully they are all gone now.

One bonus --- i can drive 2 led bulbs off each transformer. With halogens, it was one bulb per transformer. Brightness is unaffected whether one or 2 bulbs is connected.

Dimming is working OK too.

The only minor negative, I do think halogen light quality is a bit better, and when you dim halogens they change from bright white to a neat dull orange glow.

Ideally I'd have changed all the fittings. But, that is the difference between a $1000 job and probably a $5000 job.. Fittings change might need an electrician plus replastering and painting.
