3.1 Performance and lifetime
The lamp output spectra and typical output levels over lifetime are shown below.
3. Lamps
It is normal for the output to decline over the first several hundred hours of use and then stabilize at a level ~70% of
the initial output for the remainder of the lamp life. If the lower power regions of the output spectra are being used,
it may be desirable to replace lamps more frequently to maximize signal levels.
