Dear Rei .
The first M6 were able to mesure total light level to a certain value .
Those had the 2 leds shutting off if the EV was too low for the 
system to process such low values .
The 2nd batch were also able to mesure only total light level , but 
the 2 leds , instead of beeing shut off , actually blinked when the
EV was too low .
Am I wrong ?
