Boy this really makes my day. Lets see, I could go to Duane Read and buy a 5/10 dollar flash light, a pack of Double As, and an extra bulb for oh, roughly fifteen bucks. Result? Anywhere from half to three or four days of nice bright light.
Or wait, I could purchase a 40 dollar gizmo that looks like it could break any second, and provides a tiny beam of light for two minutes, after shaking it furiously.
I think I've made my choice...
