Oh guys, come on.   
   Unfortunately I still cannot try your suggestions as I am not at home, but   
   please, let's try to be pragmatic.   
   If any of you have ideas, schematics or whatever, post it. I have limited   
   components at home and some are just scavengered but I would give a try to any   
   good idea that would allow me to keep 4 bright led on all night long.   
      
   BTW, is replacing the battery with a capacitor an idea worth trying/meaningful?   
      
   Thank you all
