Go with the Solo Logic, better yet two of them. I run a 50 watt MR16 halogen homebrew light with a one watt Xenon strobe in back. I have never seen anything while commuting that can compare to that strobe. Power is safety; you may only need 10 - 15 watts to see, to be seen power=survival. I had a 100 watt PAR36 light once. Check out the lighting thread and the geek thread. Over-driven ultrabright LEDs are not as efficient as a good halogen. Just lighter (pun intended) and stylish. Oh, strobes; check www.allelectronics.com and look up the Amber Xenon Flasher.
