I'm very interested in finding out more about oral D3 (as found in reptile supplements), the types available, and how it is absorbed and metabolised. I guess...
Frances, I looked through the Excel sheet you have posted. There is one issue that I think you may want to look into: On most of the lamps, you list minor UVC...
Jukka, I beg to differ. In fact, I question the spectralradiometer sensitivity and uncertainity in the 254 +/-8nm bandwidth. Yes I agree that saturation...
Steve, I am not criticising the Solarmeter instruments - quite the contrary. The issue I bring up is taking measurements at the instruments' extreme range,...
this is just from my experience in electronic weighing but accuracy is greatest at full scale since you always dither a couple of counts and u can see that a...
Hello to all. I am here because of a discussion on the Urozone2 group. Jenn brought up this group during a session and I thought it would be a good place to...
Jukka (and Andrew)... all good points. Also the Inverse Square Law would help explain drop off from 4 to 1 to 0.1 or less at 30cm (12 inches). In any event,...
Steve, Jukka, Andrew, Fascinating information! All I can offer are a couple of observations I've made. Firstly, the inverse square law definitely does not...

"Meter having a bad hair day" lol. Interesting readings. Very low UVB as expected from almost all "household" lamps. But those Sylvania Mini Lynx T-20W things...
Hello Zsuzsa, ... opinion/experience as anyone else was.<< You are. That was already decided. ... post go on the list is very impolite to say the least.< I...
What happens if you remove the glass filter on the small domestic down light type halogens? I undersatnd that the filter is there specifically to stop the UV...
when i looked at the frequency colour spectrum for incandescent lamps you can see it does extend in very small amounts into the uvb and with halogens its a bit...
Sorry about that I didn't mean to send and empty email. Can you tell me the price range for both? I know the more that order the more of a discount you can...

Ordinary incandescent bulbs don't emit any UVC.... the model 8.0 meter always reads 000 to them no matter how close you get. Any 60 (or 50) hertz noise is...

Francis.. good graphs. Remember to include those Hawaii >500 readings in the summer solstice file. A winter solstice would be interesting too.... really low...
Hi, everyone. At last I have completed making the database and charts for the Spring Equinox "World UVB Recording Day" that so many of us took recordings for. ...
Uh-oh.... At point blank range my model 8.0 gave me the following readings for UVC with ordinary incandescent lamps: (uW/cm2) Safeways 100watt standard bulb 1 ...
I means YOUR sample of lamps really DO have a tiny "point blank" emission of UVC. So do Euro tanning lamps.... especially the "open quartz" industrial HID HP...
Maybe it's something to do with the high voltage we use? No-one has ever been able to answer my questions about whether our European high-voltage fluorescent...
Frances, Your work is marvelous as always. When you are finished please make a page fpr the info site. It will be a great reference. Best regards, BobMacCargar...
What happens if you remove the glass filter on the small domestic down light type halogens? This is a different story then you originally asked. Without the...
... That really depends on the halogen bulb, many halogen bulbs are now have a UV blocking additive to the quartz which will cut out most of the UV produced....
in my old age i can see i have been wrong so many times that i leave other peoples 'irresponsiblity' as an open question i don't think people not understanding...
Bob, Ok, it then just sounded more impolite to me than it was meant to be. Let's forget it. You know, I'm a person with about 35 years experience in reptile...
a point source may but tubes add in uv from the sides of the tube my 6.4 meter on a spectronic's uvb tube was about a power of 1.67 drop off rather than 2 ...
