Well, I picked up my LTA at Petco. I can assure you they were using regular florescent, since they normally only keep fish (Normally). The Anemone was out and spread wide open, so I think it will be ok. FOr long term success you should consider stronger lighting and feeding it to help it along until he gets happy. I have 440 watts of VHO
over my 75G and I had a BTA keel over. Anemones are difficult, even the 'easy' ones to get acclimated and keep them happy. Read the links in my previous post and then read some more. The more research you do, the better the outcome for both of you..
Best of luck
