Well, like I said - I recalculated for the flux of the 15 W lamp. An hour of zapping gets you to 1.72 J/cm^2 which is very close to your 1.8 J/cm^2 figure.

- jennyyang 7y agoWe are not disagreeing here, I think your 60 min calculation is correct. My point is that your calculations are at 50 cm and you get a much lower time for exposure if you bring your light bulb much closer and figure out a way to reflect the UV light so that more light from the bulb hits the intended target.
