Hi, So I currently have a White’s Tree Frog under a 13 watt 5.0 or 5 % UVB bulb in a 20 gallon tall terrium , I’ve seen some say a you should use 2.0 for frogs but I cant find a 2.0 anywhere, as exo terra now sells their 2.0 light as “natural light” that contains no uvb just UVA do you think a 5.0 would be completely safe for a White’s Tree Frog thanks -Brett
