UV bulb coil lights?

[Michele654]

Can anyone tell me the dangers and/or problems some are experiencing with UV coil lights for their beardies? I have two 10.1 UV coil lights and one 18inch long uv light. I can't see how one 18in light could be enough for a 75 gallon tank? Any suggestion on this?

Well, I do have this link... it is highly technical, but using the diagrams you can see the correct spread of UVB from each light.

let me know if I can help you with the specifics... I know basics... Red Ink Aus, ladyknite both are more informed than I am...but I am willing to share what I do know.
