Here's the corrected chart. Note the correct metric is microWatts per cm2 (not microWatts per m2.) To convert microWatts per m2 to microWatts per cm2, multiply by 100 and vice versa. Hence, the Hamilton lamp (at 5") produces about 13w UV-A and 0.69w UV-B. This is for this particular lamp only.
We lost power for over a day and a half during a snow storm, but aquarium temp went only just below 70 and everything was fine.
OK, thanks.. so to make sure I'm getting that straight is that from the bulb?
So at 10" in a tank and assuming about 6" from surface to bulb your UV-A (16") is .2mW/cm2 ...or 2W/m squared..
So entry..13w.. in the tank at stated distance.. 2W
so about a 85% loss @ 10" deep. .
UVA fluence of about 20.5 W m2
and a UVB
fluence of about 1.2 W m2
Incident solar approx..
So being a bit liberal on rounding about 1/2 of solar..
Higher than I was expecting..
