After doing some searching on two or three different sites, I'm about half scared to ask this question,,, seems to be a bit religious/political for some odd reason, but here goes. What is the current draw of a normal Gossen Luna Pro light meter? Any other light meters (analog) current draw you know of that used mercury cells? What I found, looking at the various adaptors, was a feeling that around 5ma was about maximum that the various diode silver oxide replacement adaptors would tolerate. I'm looking at the MAX 6037 in surface mount as an option. I wish I could find my old battery design manual from GE Opinions?
