Does anyone know if there is a claim for a brighter light than this on the market today? (Darkness Dominator - http://www.troutie.com/Products/Detail/Darkness-... )

I own a Trout Light 7 UP light (now discontinued) - 1,700 Lumens and that is bright but 2,600 Lumens. That's very bright! Is there a limit to how much light one needs when riding...mmmmm? What is the ideal trade-off between light output, battery endurance and weight/size? Any thoughts? Comment? Opinions?

Specification for this beast:

Leds Cree XML U2
