here's the thing. they say, dont go below 3v per cell static. that will damage it. however, your voltage drops under load, so they say dont go below 2.5v per cell under load. i guess i will be a bit more conservative and call it 8v per cell for the second LED. i am usre it will be fine at 9v and 8v.
Thanks,

OK ..... It's done. With fixed resistors the closest I could get was 9.02V and 7.93V
To get it perfect would have meant using preset pots, which I wasn't keen on, because of the possibility of accidental adjustment due to vibration or crash.
Shouldn't take long to get to the US from here.
