Will you please give me the name of a specific bulb or tube that emits in UVA, and also please show a graph that demonstrates the bulb/tube UVA wavelengths (320, 340, 360, 380, and 400) vs. their micrometers/cm squared at a given distance. The UVA from 320 to 400 is on the horizontal axis, and the mW/cm^2 is on the vertical axis.
BobMac believes (it's his right, and he might be correct) that the one big spike in the middle of the UVA is all that iguanas need.
So far I know of only one lamp that produces UVB + one big spike in the middle of the UVA, which can be backed up by actual lab science. The information comes from a private source, and I sincerely want to avoid bad blood between us.
