Various size LED linear lamps and easy shipping with snap fit connection

An LED linear lamp assemblage. The assemblage has two LED linear lamp sections, each LED linear lamp section with an elongated tube with a transparent or translucent cover that connects to the base portion that defines a space inside. A circuit board with a plurality of spaced apart LEDs and electrical connectors are disposed within the space. At first ends of the two LED linear lamp sections are pin(s) for connecting to a power source, and the electrical connectors are located near second ends of each LED linear lamp section. A joiner unit is provided for mechanically connecting and holding the two LED linear lamps sections together at their second ends. When the two LED linear lamp sections are connected at their second ends to establish electrical connection the LED linear lamp assemblage is complete.
