If you don't mind spending a little more, the Lezyne Super Drive is a very bright, self-contained light and can be bought on-line for about $100. It also runs on 18650 batteries, and you could extend your run times significantly by buying a charger and some spare batteries.
tarwheel, I am catching on to that real quick!

..First I was running the real cheapos..$1.50 cheapo Power Beams.. Then I happened to get some 5W 270lu flashlights, for around $4 each..Wow!!! Not only do they light up, they even look cool too. Moving ahead, I am saying if measly little 270lum flashlight can do this good, I ordered a 1300 lum flashlight powered by one 18650 battery. It hasn't arrived yet.But, judging what a 270lum $4.00 light can do, a $25 1300lum should be even better.. Plus, I plan on running double too. All my bikes are road bikes. No funny looking bags, panniers and stuff, so my lights got to look cool like the bike and me...
