The Stellar Festoon 'starter' includes a power adapter that plugs in to a wall socket. It is called 'starter' because, having the adapter, it starts the variable length of festoon lights. The starter box includes a power adapter, a 2m lead, and two 5m festoon lengths. Each festoon length has 7-8 bulbs, 70cm apart. Extensions of the same or different colour can be added to this set.
