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
