Frequently Asked Questions

How does the 90-0071-03 differ from the 90-0071-06?

The primary difference is the electrical lead configuration. The 90-0071-03 features stripped radial leads exiting from the perimeter of the lamp base, while the 90-0071-06 uses axial leads extending from the end. Both models share the same characteristic cadmium wavelengths, principal dimensions, lead length, and recommended power supply.

What ultraviolet wavelengths does the 90-0071-03 produce?

The lamp produces characteristic cadmium emission lines at 229 nm (UV-C) and 326 nm (UV-A). These wavelengths support spectral measurements, optical reference applications, and compatible ultraviolet detection systems.

Which power supply is required for the 90-0071-03?

The Jelight PS-9 power supply is recommended for this lamp. It is available in 115 V (99-0033-01) and 230 V (99-0033-02) versions and is sold separately. Select the appropriate version for the available electrical supply.

What safety precautions are required when using the 90-0071-03?

Avoid direct eye and skin exposure to ultraviolet radiation by using appropriate UV-protective eyewear, shielding, and protective clothing. Disconnect the power supply before handling or servicing the lamp, allow it to cool before replacement, and follow the equipment manufacturer's electrical safety procedures. Provide appropriate ventilation and assess potential ozone exposure until the lamp's ozone-production classification is confirmed.
