Lamp

To sign lamp, take your non-dominant hand and lay it out flat in front of your body, palm facing down. Then take your dominant hand, and resting its elbow on the fingers of your non-dominant hand, make a gesture of a bright light shining: start with your fingers all touching each other, then open them up, like the sun shining or a flashlight being switched on.

An alternative ASL sign for lamp is to simply make the sign using the dominant hand and forearm, excluding the non-dominant hand and forearm, which serves as the table top.
