A lamp is disclosed, which includes a barrel, a light emitting component, a switching assembly and a circuit component. The light emitting includes a lamp panel group, multiple far-shot lamp beads and a near-shot lamp bead. The circuit component includes a master control circuit, a switching circuit and a circuit for regulating a poly floodlight state; the switching circuit is connected with the switching assembly and the master control circuit, and transmits triggering signals, which characterize that the switching assembly is pressed down or released, to the master control circuit; the circuit for regulating a poly floodlight state is connected with the master control circuit and the light emitting component, and regulates luminous power of the far-shot lamp beads and the near-shot lamp bead in the light emitting component. And the lamp is capable of conveniently realizing regulation of a poly floodlight state.
