BBC Article on LED Lighting
Whilst not strictly IT related, this is a very interesting item from them: BBC News - The LED lighting revolution
We have been looking at LED bulbs for the home and anything that provides more light for less power than current 'power saving' bulbs can't be a bad thing. I remember as a kid having to wait for the TV and radiogram (ask Bossman!) to warm up before you could use them. That's what current energy saving bulbs are like!

Apparently they have just managed to make hid LEDs that can match the output of halogen with similar heat output. Despite their efficiency heat output is still the main issue with large heatsinks needed for current gen led replacements, at least the ones we can get here.
