Superbright little LED flashlights

I bought some of these 7W Ultrabright mini LED flashlights a while back and they are my favorites. They are surprisingly bright (it has a bright/dim/strobe setting) and a zoom feature to focus the beam on a small area or spread it out. A twin-pack is just $9. It uses either a single AA battery or a 3.6 volt type 14500 Battery (rechargeables are cheap).
