Winner!

I got home from work today to the news that I've won a Lezyne LED Super Drive from cyclesurgery.com in their Christmas competition.
I'm looking forward to trying it out when I receive it. For touring it seems to be a great light. With a claimed 450 lumens output it should be bright enough for mad night-time dashes to campsites. Also it's USB chargeable. Which brings me nicely onto the topic of power. I'm split between getting a dynamo hub with a USB charger or a solar panel USB charger. I'm still researching the topic; when I've made a decision I'll post it here.
