A light tube including a heat sink, a light transmissive cover disposed on the heat sink, and at least one light source module is provided. A containing space is formed between the heat sink and the light transmissive cover. The light source module includes a carrier, a plurality of first light-emitting devices, a plurality of second light-emitting devices, and a plurality of non-light-emitting passive devices. The carrier is disposed on the heat sink. The first light-emitting devices are arranged on the carrier along a first straight reference line to form a first line of light-emitting devices. The second emitting devices are arranged on the carrier along a second straight reference line to form a second line of light-emitting devices. The non-light-emitting passive devices are disposed on the carrier and between the first and second lines of light-emitting devices and electrically connected to the first and the second light-emitting devices.
