The Lite-Netics C9 Magnetic Christmas Light Stringer is a 25' pre-cut strand of 25 empty C9 (E17) sockets on 12" spacing, with male and female plugs already installed. Every socket base has a neodymium magnet built in, so on ferrous metal — steel roofing, gutters, drip edge, flashing, metal buildings — the strand snaps straight onto the surface with no clips, tabs, or adhesives.

Plug strands together end-to-end, or cut a strand down for a short run. Featured on Shark Tank and built on Lite-Netics' patented magnetic socket design, it is the fastest way to hang and take down C9 lights on metal.

Compatible with any C9 (E17) bulb — LED or incandescent. Works great with our ProCore® LED bulbs, the same commercial-grade bulbs used by professional holiday lighting installers.

Bulbs shown are not included — this is the stringer with magnetic sockets only. Magnets hold on ferrous metal only; they will not stick to aluminum, vinyl, wood, brick, or shingles.

Questions & Answers

Quick answers about the Lite-Netics 25' magnetic C9 stringer with 12" spacing and green wire.

What surfaces will the magnetic sockets stick to?

Ferrous (iron-based) metal only — steel roofing, gutters, drip edge, flashing, and metal buildings. The magnets will not hold on aluminum, vinyl, wood, brick, or shingles.

Are plugs included?

Yes. Each 25' strand comes with a fused, polarized male plug on one end and a female plug on the other, so you can connect strands end-to-end.

Are bulbs included?

No. This is the stringer with 25 empty magnetic E17 sockets. Any C9 (E17) LED or incandescent bulb fits — our ProCore® C9 LED bulbs are a direct match. ProCore® LED bulbs

Can I cut the stringer shorter?

Yes. Lite-Netics strands can be cut between sockets to custom lengths; finish the cut end with an SPT1 slide-on plug. SPT1 slide-on plugs

Stringer or spool — which should I buy?

Stringers are pre-cut 25' runs with plugs installed — grab-and-go for most homes. The 250' magnetic spool is for large or oddly sized runs you cut to length yourself (plugs sold separately). C9 stringers and spools
