Measurements that I've read of outdoor UVB levels taken near the equator resulted in give or take 3-400uW of UVB(philips uses mW when measuring their lamps...ie:.03-.04mW). A standard current Philips available lamp (cdm) outputs quite a bit less(obviously due to health and safety concerns) at about 30-50uW...also assuming that is probably at a distance of less than 12 inches or so from the lamp. Average levels tested roughly @ 40 degrees latitude(colorado) were around 150uW.
There is a quartz metal halide that I'm looking at that runs a color temperature of 3500k and outputs approx 380uW of UVB which runs pretty close to normal equatorial levels.
Yeah, too much UVB is also be a bad thing...and contrary to what a lot of people think, imo, you can't see(with the eye) the increase in the THC content(as in more crystals) or how fully developed the molecule actually under various lamps. I suppose that plants exposed to more UVB would produce more tricomes(sunblock) but that doesn't say anything about the development of the actual molecule itself or it's abundance within the tricome.
