Interesting. I thought bleaching would come from not enough light. I would think your BT would self relocate if light was to intense. Do you target feed?
Bleaching can come from the shock of going from "less light" to "more light" if the tank is not "acclimated to the light. People say that T-5s are supposed to last a year, but I dont believe that they are any different than any other fluorescents and are probably dropping in intensity after 5-6 months .. Then going from a bulb such as currents to U-V (the best out there IMO) there is going to be a big diff in intensity/par. Anemones arent always smart enough to move. Especially when they were not receiving enough light, they arent going to move if all of a sudden they are getting enough light..
When replacing bulbs, 4 good ideas are ;
1) change one bulb at a time, or
2) raise the fixture, or
3) put some screening/shield between the lights and the tank, or
4) reduce the photo period.
"fully expanded" and/or "Larger than ever" is not always a good sign. Sometimes these animals are expanding their tissue as much as possible to increase their surface area to capture as much of the light as possible.
They wont regain their zooxanthallea as quickly as they loose it. It can tank months/year for it to recover. Keep feeding it small pieces of food (I am not a fan of silversides/sardines).
Good luck
