Todays paper has a HD add in which they again have their nine light LED flashlights, in a pack of three for $5.00. I bought two of these after Thanksgiving, and will be buying some more tomorrow. These lights are made from aluminum, and are about the size of a "D" cell battery. By adding an old 3 volt charger, and wiring light to it, Alan's dust bin sensor could be modified to use one of these.
