Buying Guide
When selecting 18/2 SPT-2 lamp cord, consider these factors to ensure a safe and reliable installation:
- Voltage rating: Most SPT-2 cords support up to 300V. Confirm your fixture requirements and local electrical codes before use, especially for outdoor or direct-burial applications.
- Conductor material: Copper conductors offer lower resistance and better conductivity compared with alternatives. Pure copper and tinned copper variants improve corrosion resistance in moisture-prone environments.
- Insulation and jacket: PVC insulation with a PVC jacket is common for SPT-2 cords. Look for flame-retardant, UV-resistant, and weatherproof jackets for outdoor installations.
- Durability under temperature: A wide operating temperature range (-40°F to +140°F or similar) helps prevent cracking in cold and hardening in heat, extending longevity for outdoor use.
- Direct burial suitability: If your lights are placed underground or in landscaping, ensure the cord supports direct burial and waterproofing as advertised by the manufacturer.
- Flexibility and ease of handling: A cord that remains flexible in cold weather and does not crack under bending will be easier to install and less prone to damage from kinks and tension.
- UL or UL-listed certification: Certification provides assurance of safety and quality, especially for fixtures connected to household power supplies.
- Length requirements: Plan your layout and determine whether a bulk roll (e.g., 100 feet) or shorter lengths fit your project needs. Longer runs may require splicing or additional protection.
- Accessory compatibility: Some bundles include vampire plugs or end fittings that simplify DIY projects. Check whether you need adapters, connectors, or pre-terminated ends for your lamps.
