Then I suppose I shouldn't feel bad about sticking to my "old fashioned" fluorescent lights. They do provide some UV-B for a very inexpensive price as opposed to purchasing the more modern and expensive LED lights that typically have little to no UV-A or UV-B and must have even more expense added to them to produce UV-B.

It was good to see that there has been some research that indicates FBT's and other frogs/toads apparently do synthesize vitamin D3 from exposure to UV-B. Also the mention that dietary supplementation of D3 and calcium may be inadequate on their own. And as I write this I see my FBT's are on top the big flat rock in the viv that probably puts them in the best location to get the strongest dose of light. Though typically they are in the water.
