A portable lamp including a socket and bulb attached to two brackets adapted for temporary connection to pre-existing supporting members of various shapes and dimensions. The brackets are connected to each other by a hinge, and each bracket has a notch arranged to receive the supporting member. To tightly grip the supporting member, the angle between the brackets is adjusted so that the edges of the notches are pressed against the member. Step-shaped edges of the notches define rectangles of progressively decreasing width to accommodate supporting members of different size ranges.
