I've always heard to replace UVB bulbs after 6 months, because they no longer produce valuable UVB after that. But after reading so much here about how much better the ReptiSUN 10.0 Tubes, I went ahead and got one. While reading the box, I noticed it says that the bulb will continue to produce UVB for 12 months. What do you guys think of this? How long before you replace your ReptiSUN 10.0 bulbs?
I use arcadias (slightly better than reptisuns but not available on your side of the pond) and I have noticed in using them for longer - I once had to use a bulb for a little over 6 months due to delivery issues and Phoebes activity levels and appetite totally dropped. I usually aim to replace mine at 5 months.
Right now, they all have arcadias, all of which were put in at the beginning of April and im starting to see a difference in Phoebes behaviour already .... I think I will have to be ordering new bulbs VERY soon!
