OK, but still you need some intelligence in the receiver....  
Fluorescents generate IR; other remote do, so do many other things.  
*Something* in the receiver has to decode it and decide if it is the 
correct remote and the appropriate signal.

Actually a smart receiver wouldn't be that hard to build; google for PIC
