While working at Arctica Cubed, I loaned my headlamp to someone volunteering inside an ice truck so they could review inventory, then subsequently had to rush out to handle a crisis. They didn't leave my headlamp behind with the supervisor, but I'm hoping they held onto it, hoping to return it to me directly. It's the smallest headlamp Petzl makes, and has a retractable cord. You can see it here: http://www.petzl.com/us/pro/headlamps/ultra-compact/elite.
I'd love to have this lamp back, as I can't afford to replace it. I am, however, happy to cover shipping and send some awesome swag.
