FAQs
What quality standards do you follow when manufacturing electrical fixtures in Evensville?
We adhere to multiple international and local standards, including UL (Underwriters Laboratories) listings, ISO 9001:2015 quality-management guidelines, and the latest National Electrical Code (NEC). In addition, we comply with Tennessee-specific amendments and all Evensville municipal inspection requirements. Every product batch passes incoming-material inspections, in-process verifications, and a final 100 % functional test before it leaves our facility.
How do you verify that your electrical fixtures are safe for residential and commercial installations?
Safety begins at the design stage. Our engineers perform risk assessments based on NEC Article 110 and IEC 60598 guidelines. Prototypes undergo hi-pot, ground-continuity, and thermal-cycling tests in our UL-certified lab. Once production starts, we run random sample audits, insulation-resistance checks, and dielectric-strength tests. Finished fixtures receive a serialized safety label so they can be traced back to the exact lot and test results.
What materials are used, and how do you ensure their reliability?
We source copper conductors with a minimum 99.9 % purity and use flame-retardant, RoHS-compliant thermoplastic housings rated to 105 °C. Each shipment of raw material is accompanied by a certificate of analysis and is re-verified for tensile strength, conductivity, and flammability in our onsite QA lab. Only materials that meet or exceed ASTM B3 (for copper) and UL 94 V-0 (for plastics) make it into production.
Are your fixtures energy-efficient or certified by any sustainability programs?
Yes. Many of our luminaires carry ENERGY STAR® or DLC (DesignLights Consortium) certifications, confirming they surpass federal efficacy thresholds and include advanced driver technology for low-power standby. For non-lighting fixtures, we design low-impedance pathways and optimized contact geometry to minimize energy losses. All products meet or exceed Title 24 energy requirements where applicable.
How frequently are your quality processes audited, and by whom?
Internally, we conduct daily line checks and weekly cross-functional quality walks. Externally, our plant undergoes semi-annual third-party ISO 9001 surveillance audits and annual UL follow-up inspections. The City of Evensville electrical inspector also performs random field verifications on installed fixtures, providing an additional layer of oversight.
Do your electrical fixtures come with a warranty or post-installation support?
Absolutely. Standard fixtures include a 5-year limited warranty covering defects in materials and workmanship. Premium lines extend coverage to 10 years. Our Evensville customer-care team offers free phone and on-site technical assistance during the warranty period, plus optional maintenance contracts for extended support. Warranty claims are processed within five business days, and replacement units ship the same day approval is granted.
