Can you obtain the spectral power distribution charts for these
lights? If so look at them and see where most of the light peaks in
nanometers. If you find most of it in the range from about 380 to 430
nm, they should work well because this seems to be the ideal range
for Pt/Pd. I have in the past not found the relationship between K
temperature and UV output to be reliable.
