What NARVA Light Sources does

NARVA Lichtquellen GmbH + Co. KG is a privately held, medium-sized specialty light-source manufacturer based in Brand-Erbisdorf, Saxony, Germany, employing approximately 110 people. The company operates from a single, vertically integrated production site that includes its own glassworks (producing glass tubes since 1972), lamp assembly, and a DAkkS-accredited independent testing laboratory operating across the 200-800 nm wavelength range.

The company's core competencies are in UV and visible-light spectrum development, glass processing, glass-to-metal sealing (with patented vacuum-tight technology), and phosphor coating. Its product portfolio spans four categories: (1) specialty fluorescent and UV lamps — including tanning/sunbed lamps produced under the Cosmedico, iSOLde Licht, and Wolff System licensed brands, plus weathering test lamps, BIO vital full-spectrum lamps, and yellow special lamps for clean rooms; (2) LED tubes in T5 diameter with proprietary glass-envelope protection, including the Semicon Light SL-T5 Gen II; (3) solar thermal vacuum tubes — both heatpipe and direct-flow variants — together with partner-branded collectors from AkoTec, EHT, and VacuSol; and (4) luminaires and UV-C air disinfection devices (table-top, floor-standing, and the 2022 Doppelleuchte combination luminaire), plus a Schulungsleuchte educational lamp. The company holds ISO 9001, ISO 13485:2021, ISO 50001, IEC 61549, and ISO/IEC 17025 accreditations, and has cleared an FDA audit (21 CFR Part 820) for tanning lamps in June 2023.

NARVA generates revenue primarily through B2B quote-based custom manufacturing for commercial and industrial customers, with multi-year supply relationships for branded tanning lamps running through sister companies JW Sales GmbH and JW North America Inc. under parent JW Holding (which acquired a majority stake in 2000). Pricing is not publicly disclosed; offers are tailored per inquiry with EXW Incoterms and standard 14-day 2% / 30-day net terms. Secondary revenue comes from accredited testing-lab services and hardware sales of solar thermal and UV-C devices. Customer segments span tanning industry OEMs, industrial manufacturers (photochemistry, reprography, PCB, semiconductor lithography), solar thermal installers, healthcare/education, and weather-testing laboratories.
