Abstract: A light source attachment intended for use as a lantern for camping or for use in the home. The light source attachment may function also as a container for drinking water or other fluids or solids or for the measurement of volume of fluids or solids for use in cooking. A light source is positioned in order to direct a beam of light through a non-opaque lid and into a non-opaque container. The container may be modified with reflectors at its bottom or around its sides. The light beam encounters the side and bottom of the container and naturally illuminates all of its surfaces. The container thereby emanates a glow and thereby provides general illumination. The container may be filled with water during its use.
