This may help If your up for recalibrating it yourself.

I've owned a Luna Pro F for several decades, and recently it started having problems with not being able to zero the needle on the scale in bright light. So I shipped it off to Quality Light Metric in Hollywood, Ca. It came back good as new, with a calibration sticker, too. Price was well under $100.

Thanks, Joe. Sending it out for repair is a last resort.

That won't help, the only thing these have in common is the name. Gossen rather made a mess of its nomenclature. Besides calling all their pro meters Lunapro in the US, they re-used even their European names. The Lunasix F is a Profisix with added flash mode (released after the Mastersix, to pitch something against the flash enabled Autometer IIIF when flash capability moved into the mid price segment). The original Lunasix was the predecessor of the Profisix - a sixties plain electromechanical CdS meter, while the Lunasix F is a eighties digital metering computer disguised behind a pointer instrument.
