A portable light source has a base, an attachment mechanism adapted for removably attaching the base to a surface, and a substantially tubular arm pivotally connected to the base such that it can pivot between a horizontal position and a vertical position. In one embodiment, the charge components are mixed in a controlled addition process, then the newly-formed compound is heated to become totally molten, followed by a rapid quench at room temperature. The media is skewed with respect to the scanning, thus defining a media skew.
