A lamp control system with various control ways includes an AC power source; a wave generator; a driving circuit; a lamp set receiving power from the driving circuit to drive the lamp set; a microprocessor receiving power from the lamp set as driving power thereof and receiving, signals from the wave generator as driving signals; a switching circuit; the switching circuit being connected to the microprocessor and receiving the signals from the microprocessor for operating the lamp; the switching circuit also controlling current flowing through the lamp set and thus controlling the illumination of the lamp set; a sensing circuit connected to the microprocessor for detecting variations of environment illuminations and then transferring detecting signals to the microprocessor to cause the microprocessor to control the switching circuit to operate the lamp set; and an illumination setting by which a user can set illumination of the lamp set.
