A convenient-used energy-saving ceiling lamp comprises a lamp base, a lamp head, a ballast, a light tube, a lampshade and a lamp holder. The lamp holder is directly mounted on the lamp base. The ballast is made to form a concave or hollow area in the center of it, which is big enough to allow the lamp head to be mounted in there and to be plugged easily into the lamp holder, thereby reducing the whole height of the light tube. The light tube is connected with the ballast via ribs. The lamp head and lamp holder can use the screw type, bayonet type, double-ended bayonet type applied in glow starters, and pin type plug and socket applied in double D type ordinary light tubes. The obvious advantage is the convenience to install, use and maintain it.
