I have spent some time playing around with the 1W Luxeon LED to do 1km 
optical data transfer.  But base on my experiments so far, the LED has 
problem overpowering the daytime sun.  And the limited 500mA peak 
current for a 350mA rated LED does not hel.  But the low peak current 
still puzzle me.  The latest 1.54A LED will not do unless its peak 
current can take more abuse.  Anyone has data to fault the brief datasheet?

So I am jumping over to the laser diode camp.  I had sent out some 
enquiries?  To cut short this process, do piclist have some references 
and shops (online) of liking.

Thanks.

Cheers, Ling SM
