Thank you
I don't see a good way too make it a larger picture, but I can make it a pdf file, so I will PM you that. (If I can again figure out how to upload an attachment????) EDIT: I found the way to do this - the paperclip in the header.
If I wanted to rely on a "standard light" for adjusting the sensors to a known PAR the only one I can think of is a Finnex Fugeray or Ray2. I did measure the PAR for one of them and my readings agreed with the data on I suspect you could get one of the shortest ones and use it as a "standard".
