What is the rated spectral tube lifetime?
The lifetimes of the spectral tubes will vary considerably depending on the fill gas, the duty cycle of the tube, and the operating voltage. At the recommended duty cycle, the spectral tubes should last for hundreds or thousands of hours of operation with the 5 kV SE-9460 Spectral Tube Power Supply and Mount. (A considerably more expensive power supply (SP-200-AM Electro-Technic) with variable output power is available for special order.)
Continuously operating a tube for which we recommend power cycling will shorten the life of the tube to a little as five minutes (in the case of hydrogen). Please refer to the chart below for the recommended duty cycles:
All of the spectral tubes have a 1-year warranty from Electro-Technic Products Inc.
