Our premium C9/E17 intermediate base commercial light strings are engineered for long-term permanent landscape and holiday decoration applications.

Key Features
- 16AWG SPT-2 heavy-duty wire: UV-resistant outdoor wire with anti-UV coating prevents aging, cracking, and discoloration under long-term sunlight exposure

- Parallel circuit anti-burnout: If one bulb burns out or loosens, all remaining bulbs stay lit — no whole-string blackout
- End-to-end connectable: Built-in male and female plugs on both ends for connecting multiple strands to cover large areas
- 1200W max load (10 Amps): Meets US commercial electrical safety standards for large installations
- 15-inch socket spacing: Balanced density for both close-up and viewing-distance applications
