What is a prelamped string compared to a stringer?

  • Prelamped stringers: wire with bulbs screwed into sockets; best for basic Christmas lighting plans.
  • Stringers / spools: wire with sockets, bulbs sold separately; best for custom themes, lengths, and power planning.

Advantages in buying bulbs and strings separately

  • Replacement bulbs: nickel vs brass based to prevent corrosion; higher diode count in LED retrofit bulbs.
  • Stringers / spools: weep holes for increased weather resistance.

What size bulb do I need?

  • C7: ground level, one-story roof outlines, bushes
  • C9: ground level, two-story roof outlines, tall Evergreens
