The invention discloses a stacked work lamp which comprises a base and at least two lamp bodies sequentially stacked and mounted above the base from top to bottom. The stacked work lamp is characterized in that the adjacent lamp bodies can be rotated to irradiate at opposite angles, and a rotation limit structure capable of preventing the lamp bodies from further forward rotation after the lamp bodies are rotated to irradiate at the opposite angles is disposed between the adjacent lamp bodies. Compared with the prior art, the stacked work lamp has the advantages that more than two lamp bodies of the stacked work lamp are sequentially stacked and mounted above the base from top to bottom, so that wide lighting range is obtained by moving one of the adjacent lamp bodies and allowing the lamp body and the other lamp body to irradiate at the opposite angles; and furthermore, the rotation limit structure between the adjacent lamp bodies prevents further forward rotation of the adjacent lamp bodies after irradiating at the opposite angles, so that the work lamps can be positioned to irradiate at opposite angles.
