Order them directly from Excelitas or via our authorized distributors. Specify the lamp length, wattage, and base type to match your system. For bulk or custom orders, get in touch with your regional Excelitas representative for pricing, lead times, and technical support.

We can create custom lamp designs with different shapes, power levels, or connection types. Share your design requirements with our team, and we will gladly help you develop a solution that fits your system perfectly.

Consider these lamps if your manufacturing processes require reliable UV sterilization, such as in the production of medical devices, food and beverage lines, semiconductor fabrication, or water treatment. They’re ideal when you need steady UVC output around 254 nm with high reliability.

They offer efficient germicidal action with low power use, long operational life, and consistent output over time. Because they emit nearly monochromatic UV (≈ 254 nm), they’re well-suited for microbial inactivation in controlled industrial settings.

Handle the lamps using clean gloves to prevent fingerprints or contamination on the quartz. Secure the units in the fixture with proper sockets and stable electrical contacts. Make sure that the reflectors are aligned correctly and check for uniform UV output before full operation.

Yes. They’re designed to fit into OEM modules and retrofit setups. You can pair them with compatible ballast or power systems and incorporate them into automated conveyor or disinfection modules.

Under normal operating conditions with proper cooling, stable current, and minimal cycling, they can deliver thousands of hours of effective service life before performance drops measurably.

Very little. Clean the quartz envelope periodically and ensure that airflow and cooling remain unobstructed. Staying within the recommended electrical and thermal limits helps maintain their efficiency.

It is safe when installed in enclosed systems with proper shielding and interlocks. UVC radiation is harmful to the eyes and skin, so ensure your installation prevents direct exposure. Always follow Excelitas’ safety guidelines.
