sorry to dredge up an old thread, but i’ve been doing a lot of research on uva/b and figured out (aka read it) that the emissions are a range, not a number, so the uva lights everyone says are worthless that others claim worked for them actually put out some uvb, so they are useful, probably moreso than straight uvb, since you can run them alongside your regular lights and not overload them with uvb and do damage. the epiphany came when reading this. notice the chart that shows the range. i wonder why nobody mentions that? am i just overmedicated?
