Mini light strands are used on wreaths, bushes and tree trunks alongside a C9 roofline: 4" LED Minis (1 Strand) (from $15.00) and 6" LED Mini's (1/Strand) (from $14.50), or by the case as 4" Spacing LED Mini's 24/Case and 6" Spacing LED Mini's 24/Case.

Turning the run map into an order

  1. Total sockets across all runs. That is your bulb count and your clip count, split by surface.
  2. Total footage across all runs, plus waste allowance. That is your socket wire.
  3. Count runs and jumpers. That is your male and female plug count, plus spares.
  4. Total jumper lengths. That is your lamp cord.
  5. Count outlets feeding the display. That is your timer count.

Compare the total against a kit. If a kit's quantities cover your run map with room to spare, it can be the simpler order; otherwise buy parts individually. For kit sizing, see how to size a C9 install kit. Or browse everything at the Christmas Light Supplier shop.
