Update. 2009 season version:
About same design as before, but now with two P7 LEDs in series. Two modes, 1.75A and 0.35A. Modes should give about 1100 and 260 lumens and burn with the belt pack shown 1:25 and 7 hours. Enough for my runs, low mode is fine for slow path jogging, high for my typical ~1 h races.
Weight without battery is 114 g and total weight with shown nimh battery pack 337g. Li-ion might save ~70g.
Light heads are now monteed with rubber bands. I may keep it that way and just add some double sided tape to prevent sliding. It is nice to be able to make beam spot changes by changing one of the heads direction. It's also good to have two heads, you can modify beam by using different lenses on the heads.
