I have an answer for anyone whom cares. From 150-100 µW/cm² UVB at the basking spot.
photo-kerato-conjunctivitis aka snow blindness is the result of too much for too long. Sun burnt corneas. This is greatly simplified UVB is only part of the equation UVI (index) needs to be calculated to be perfectly precise. I am still learning all this but beware not all bulbs are created equal.
