The Surya Vegtubes are supplied with one or two connecting cables, depending on the function of the lamp. The Stand Alone version has 1 connection cable that can be extended with the power cable via a special plug connection. Vegtubes that are part of a Daisy Chain each have two connecting cables. With these Vegtubes, the primary function of the connection cables is to connect the lamps together. The first or last lamp must then be connected to the mains, and this works in the same way as with a lamp in the Stand Alone version: the remaining connecting cable is connected to the power cable via the plug connection. This power cable with plug is not supplied with the lamp. The idea behind this is practical: a Daisy Chain can hold a large number of lamps, while you only need 1 power supply with plug to supply the whole thing with power. Every lamp with its own power connection would be superfluous and wasteful. Connect a plug yourself It is also possible to connect a separate plug to the connection cable yourself.
