The 1,000 ft spool outperforms shorter spools on cost-per-foot and supports 4–8 medium residential properties per spool depending on bulb count per home. Pick the spacing by the look: 15″ is the residential roofline default (paired with Tuff or Minleon V2 C9 bulbs), 12″ reads denser from the street for commercial, 6″ is for tight-coverage accent runs. Pair SPT-1 (0.030″ jacket, indoor \/ sheltered residential) or step up to SPT-2 (0.045″ jacket) for cold-climate commercial — both are 18 AWG copper so amperage capacity is identical; only the jacket thickness differs.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c!-- Section 3: Verified specs --\u003e\n\u003ch2\u003eVerified specifications\u003c\/h2\u003e\n\u003cp class=\"clhq-source-note\"\u003eEvery value below is pulled from the printed spool label and the bulk-wire cluster page.
