摘要： A lighting apparatus includes a light passing cover, a light strip, a heat dissipation plate, a manual switch, a driver and a bottom cover. The light passing cover defines first elongated cavity. The light strip is mounted with multiple LED modules. The heat dissipation plate is used for mounting the light strip on a first side of the heat dissipation plate. The manual switch is disposed for selecting a switch setting. The manual switch is placed on the first side of the heat dissipation plate. The driver converts an external power source to a driving current supplied to the multiple LED modules. The driver is electrically connected to the manual switch for controlling the driving current supplied to the multiple LED modules to adjust an output light of the multiple LED modules according to the selected switch setting. The bottom cover defines a second elongated cavity.
