A tube light comprises a tube having a continuous length, a plurality of light units adapted to be secured on the tube, and a fastener for securing the light units on the tube. Each light unit comprises a socket portion of which the upper part is formed with a column having an external thread, and the column can just pass through a perforation provided on the top surface of the tube. Thereafter, the light unit can be secured on the tube by the fastener such that the external thread of the column is engaged with the internal thread of the fastener. Contacts extend from inside of the socket portion of the tube and lay on the upper surface of the socket portion so as to press against conductor strips which extend continuously underneath the top surface of the tube and can be connected with an electrical power source. The bottom of the tube is open, and after the light units are mounted on the tube, the bottom of the tube can be enclosed by a lid having a dimension conforming with the length and width of the tube.
