      Doug - have you considered the effects of a single LED failure in 
      this scheme? I suggest that at least 2 such strings are arranged in 
      parallel so that everything doesn't go black when one diode dies. 
      (Yes, I know LEDs don't fail as often as incandescant lamps, but I'd 
      hate to be left in the dark on that one rare occasion when a failure 
      did occur!)
      
      regards
      
      Rowland
