Thanks for sharing. I had a problem with my first tort from a Coil bulb. That's what sparked my interest into the subject.When I first got Nitro before I found this forum I got so caught up with must have uvb, loads of uvb or he will get deformed I bought an absolutely ridiculous tube it was too big, mounted too low and hurt my eyes when I looked at it and he never came out of his hide the whole 3 months I had it. After researching and reading on this forum I realised I had it all wrong and switched out to a better tube and added some led lights so I could run the uvb tube for fewer hours and the change was instant. He was so much more active and I just felt so bad for subjecting him to that horrible light for as long as I did. Being in the uk I feel i do need some artificial uvb as the weather here doesn't permit many hours outside but i wish I'd found this forum sooner and threads like these to help me understand what I was doing wrong
