>>Talking about lights and LEDs: Notice how many flashlights and those "head-lights" feature powerful LEDs nowadays. In order to look modern nowadays house have to have those halogen lights, but I find them a PITA as they keep blowing (AND give off so much heat) and are dear to replace. Recently, in an electrical wholesalers, I noticed some LED lights in the same housings as the halogen. I asked the guy how long they last in comparison. He said like forever. I forgot to ask if they can be put in existing halogen set-ups. Anyone know?

>Certainly LED replacements are available. Use about a 10th of the power and last almost infinitely longer. On the downside they are more expensive and not as bright. Examples:http://www.yourwelcome.co.uk/acatalog/LED.html

Cheers Viv. Mmmm, maybe quite an outlay at first - but worth it over the years, i guess. I wonder about dimmablity as well. Not all halogens will respond to the dimmer switch. And don't LEDs use multiples of LEDs to control brightness, so stepping up or down rather than dimming?
