We about fell over when one tube we have on a hospital tank had one of the best UVB readings of any of them, its 7 months old!!!
I figured it was about shot and needed replacing. Very strange, we changed over to the MV as 4 years ago we had problems with the tubes and poor output. Since then I had not bothered to check any tubes for years.
The workings of the Active UV heat 100 watt spots are really unique, actually gaining reading as you get farther away til a point then it reverses and also greater reading spreading out as it ages, but new ones are reversed. Another thing we noticed is that the readings are really high for about 24 hours, then drop and remain fairly steady, so people might want to set those up first for a few day before putting animals under it.
I have about a dozen more to test that are not set up, and will get those to you as I can.
I saw you wanted to test the GE Spectrum. I have a couple of cases of those, if you want I can mail a few boxes, we use them to bring up light intensity. and for the indoor tanks of those that are normally outdoors in good weather.
BTW, we have three people here testing them and verifying them and one is a manufacture of reptile products, so they are accurate, checked by us all and then rechecked in an hour.
