Specialty Cleanroom Light Bulbs & Halogen Replacement Lamps

Hard-to-find halogen replacement bulbs for microscopy, fiber optics, UV-C, and photolithography — backed by SOS since 1981.

In most cleanrooms and labs, a light “bulb” isn’t a commodity part. It’s a specialty lamp engineered to a specific tool, and using the wrong substitute can change intensity, spectrum, fit, or heat load — risking inspection accuracy, process stability, or yield. SOSCleanroom has supplied specialty cleanroom light bulbs and halogen replacement bulbs since 1981, helping controlled environments stay operational when the spec is non-negotiable.

Today, sourcing a true halogen replacement bulb is getting harder. As global halogen manufacturing continues to decline, legacy and OEM halogen SKUs — especially fiber-optic halogen replacement bulbs for microscopes and inspection illuminators — are disappearing from standard channels. SOS specializes in locating exact-match halogen lamp replacements and, when appropriate, supporting validated upgrades to LED fiber-optic illuminators for longer life and lower heat. We also supply UV-C germicidal lamps (254 nm) for cleanroom disinfection programs and bring deep semiconductor expertise for photolithography replacement lamps. As the Ushio sales representative for Texas and the entire East Coast, SOS supports fabs with Ushio short-arc mercury photolithography lamps and the precise replacements your tools require.
