For over fifty years International Light Technologies has been developing products and solutions that meet a broad range of needs and solve a variety of challenges. ILT combines technical lighting and light measurement expertise to provide products and services that shine.
International Light Technologies was formed when Gilway Technical Lamp merged with International Light. Gilway and International Light have long and proud reputations for delivering exemplary customer service, on-time delivery, and technical expertise. Formed in 1969, Gilway Technical Lamp has provided customers with off-the-shelf and customized solutions for a full spectrum of light sources. Since 1965 International Light has been solving the inherent difficulties in light measurement through the design and manufacture of a wide range of light measuring instruments, including the most accurate light meters on the market.
In February of 2022, ILT was acquired by Ocean Insight. International Light Technologies offices, R&D efforts, certified state-of-the-art testing and calibration lab, warehousing and much of its manufacturing are located in Peabody Massachusetts, just 15 miles north of Boston.

- Polybrominated Diphenyl Ethers (PBDE)
Light Sources Products:
All of our products are now fully compliant.
Light Measurement Systems Products:
Because our products are used as measurement devices there is an exemption on RoHS compliance. However, we are developing all our new products to be compliant, and retro designing our older products on an ongoing basis. We expect to have all our products fully compliant in the next few years.
If you have a question or a concern about a certain product please contact our RoHS Department for status on that product. More information on RoHS is available from the official RoHS website.
