What is adaptive mode in few words? In the docs I found only:"This may give better accuracy for low level measurements, but may be more inconsistent overall due to the varying integration times. Overall measurement time will probably be longer." Can I demage the instrument pointing it at the sun?

Possibly, if all you are interested in is the spectrum rather than the absolute power level. Without calibrating for it, white polystyrene foam or Tyvek makes a reasonably spectrally flat reflector. Use spotread -S -H to see how flat it is. I think the Eye One can go higher than 300 cd/m^2 in adaptive mode though (If I point my i1 at my fluorescent desk lamp, I get 20000 cd/m^2 with spotread -e). I wouldn't point it at the sun though :-) Graeme Gill. Risparmia con Tutto Incluso Light: telefono + adsl 8 mega a soli 19,95 € al mese per un anno!
