**A couple of years ago, I said that LEDs would never be much use for 
headlamps (well, not in the next few years anyway). I've been forced to 
revise that opinion. Things have moved very quickly. Cree now have white 
LEDs with an output capability of around 100 Lumens/Watt. This is close to

HID lamps and LEDs have the potential to be significantly less expensive
and 
more robust. A good Halogen is around 25 - 30 Lumens/Watt, so all the LED 
guys need to do is increase power levels. This can be done with multi-chip

arrays, but heat sinking remains a stumbling block. A 15 Watt LED gets 
damned hot. You've got a 2 sq mm chip, with 100 sq mm of heat sink! Heat 
pipes and fans will address some of the issues. Still, if they manage 200
- 
300 Lumens/Watt in the next few years, you can kiss halogens goodbye. 
Especially those horrible (domestic) downlights. In fact, at 300 
Lumens/Watt, there's little point in bothering with HID lamps in
automotive 
applications.
