Solid Wire – Retrofit Fixture Whips are UL-listed, labor-saving solutions engineered for fast, reliable upgrades of existing fluorescent and LED luminaires in commercial and industrial buildings across the United States. Designed to meet the 2026 National Electrical Code (NEC) requirements—including Articles 348.20(A)(2)(5), 348.22, 348.30(A), 410.117(A,B,C), 410.137(C), 517.12, and 517.13(A)—these fixture whips simplify installation while ensuring full compliance with NEC standards. 

Each whip features solid THHN conductors, pre-stripped 5/8" (.625") and securely tied to prevent damage and eliminate lost lock nuts. Integrated Die Cast Screw-In Connectors on each end provide quick, dependable connections, saving contractor time and effort. Ideal for retrofit projects, these whips are designed for paired luminaire wiring, allowing ballast(s) or LED driver(s) to supply multiple lamps efficiently. Flexible metal conduit (trade size 3/8") in lengths up to 25 feet accommodates interconnections, while line voltage conductors share the same raceway as lamp supply wires for streamlined installation. 

Perfect for energy-efficient lighting upgrades, these Solid Wire Retrofit Fixture Whips deliver speed, compliance, and cost-effective performance for contractors and facility managers nationwide.
