I just changed Spike's UVB light and got the reptisun 10. I didn't realize that I had the other one this whole time, 6+ months, the reptiglo 10 tube. I was reading something on here and it said the reptiglo is bad for them. Spike has had that light since she was 7 months old....have I done irreparable damage? I feed her by the books, light (so I thought) by the books, temps, everything. I feel terrible, but honestly didn't realize I had the wrong light. Not sure if I ordered the wrong one on Amazon when I ordered, or not..but what is done is done. She seems healthy....always eats ok (except recently, but could be early brumation) she has grown (17.5 inches at 15 months). Is there an issue with their eyes? It never occurred to me the bulb would be bad....I feel like crying if I did anything bad to her.
