A portable lamp including at least one light source and a body having a generally symmetrical bowl-like inner surface and a rim on said inner surface, said rim extending about a central axis that is perpendicular to a plane intersecting said rim, said light source being supported in said body to project a beam away from said inner surface such that the light beam is directed at an angle to the central axis and through said rim of the body, whereby the direction of the beam beyond said rim may be controlled by rotating said body about the central axis and effectively scanning the beam in a cone-like pattern extending outward of said rim. The body is constructed as a suction holding device by having at least the immediate edge of the body surrounding the rim made of a flexible material so the rim can then be pressed against a substantially rigid window pane or the like supported in a window of a structure, to create a negative pressure sufficient to hold the lamp on the pane. The interior surface of the dome-like part of the body may be light reflective to function as a reflector and assisting in directing emitted light.
