What International Light Technologies does
International Light Technologies (ILT), founded in 1965 in Peabody, Massachusetts, designs and manufactures professional-grade optical measurement instruments and specialty light sources. Its product portfolio includes light meters, spectrometers, radiometers, and photometers configured for UV, VIS, and IR applications, alongside specialty lamps (tungsten halogen, neon, UV LEDs, and lamp holders) and custom LED lighting solutions. Core flagship products include the ILT2400UVGI+ system for validating UVC disinfection dosage, the ILT750 Bili Light Meter for neonatal jaundice treatment irradiance measurement, and the ILT960 Mini Spectrometer Series paired with proprietary SpectrILight III software.
ILT operates an ISO/IEC 17025:2017 accredited calibration laboratory (UKAS recognized, NIST traceable) at its Peabody headquarters and at a second facility in Ostfildern, Germany, servicing both ILT-branded and third-party instruments from over 40 manufacturers. Revenue is generated through hardware sales, accredited calibration services, OEM custom work, and a usage-based equipment rental program for radiometers and spectroradiometers. Customers span UVGI/disinfection system operators, healthcare and medical-device manufacturers (notably neonatal care), industrial and research laboratories, and OEM integrators requiring custom light sources. The company distributes globally via direct sales (phone/email, 8AM-5PM ET), an e-commerce storefront, and RMA-based service workflows.
Following a 2024 strategic alignment, ILT operates as a division of Labsphere, Inc., combining 90+ years of joint expertise in illuminant sources, measurement equipment, calibration, and reflectance materials. ILT remains a privately held Massachusetts corporation with 11-50 employees.
