While it is true that if used properly, meaning, mounting them at least 10 inches away with a bright white light directly beside it they should be fine. However, what is not being mentioned is that it is a very poor quality of
UVB light. This light emits LESS UVA which means it is much harder on their eyes than the Reptiglo 8 & the Reptisun 5 & 10. This light emits low wavelength frequency of UVB, which is very close to UVC emissions. It is not a favorable wavelength for D3 synthesis. They used the incorrect phosphor coating on this bulb which allows the UVC or low wavelength to filter through.
There have been no long term studies on reptiles for prolonged exposure to radiation. So, I do not recommend the use of the at all until they fix the problem & there has been enough testing done on them to deem them safe.
There have been an increasing amount of dragons getting metabolic bone disease early on. That is telling us that most of the lights out there are not emitting adequate enough UVB emissions to help maintain bone strength. Alot of times, it wont affect them until a little later on into adulthood while other times, it will affect them early on as a juvenile.
