This thread is in serious danger of becoming informative and useful.

I will be re-assessing my lightbulb replacement strategy forthwith.

Warm white is the nearest to the old tungston lamps

From that link:-

I love stuff like that.
A little learning is a dangerous thing.

I'll give that a go, ta.

Some good deals on there.

I've got a load of GU10 halogens in my house (a grand total of 15 lamps) and I'm in the process of replacing them with LEDs. I've had a lot of trouble finding decent ones but eventually found some excellent 4 LED units on a US website [url=http://dx.com/gu10-4-led-360-lumen-3500k-warm-white-light-bulb-85-265v-ac-44577DealExtreme[/url. They're perfect replacements for 50W halogens and reasonably priced if you buy in bulk, but those eBay units look similar for a little less.
