Gossen Lunasix F (01)

Gossen Lunasix F

German hand-held lightmeter. Produced around 1981.

This one, which showed up in my hometown, in exceptional good condition.
A very good lightmeter, only drawbacks are size and weight.

I used to use a lunasix. An earlier model than this. It had two ranges - low light and high light. Come to think about it, I think I broke the first one I had, and bought a second one. And I think the first one had both scales in a single display while the newer one had a scale that switched when you pressed the read button, which moved in two ways. I also had an attachment to use it as a spotmeter. I had a Weston Master V too, but the thing about the Lunasix was that it could take readings in very low light. I believe the name Lunasix derived from the claim that it could take readings of moonlit scenes. Eventually I got a Minolta digital meter and retired the analogue meters. I doubt if you can get the batteries for the Lunasix anymore.

I also remember that Gossen made a colour temperature meter. I hired one occasionally. You used it with cc filters in magenta or green, and wratten 80 or 81 series.

Thanks for your insights Bill !

I also have the Lunasix III which very much follows the description you gave of your second Lunasix. It has indeed 2 scales which turn over when you select the lightrange to work with.
It works on PX13 mercury button cells which are alas no longer produced. The newer silver-oxide button cells give a too high reading.
However, there is a conversion possible. You can read all about that on this site :

The Lunasix F you see here works on a regular 9 Volt (block shaped) battery. No problems in still getting those :-)
When using the ancient cameras that i still use it's of course a better suited outfit then a digital one ;-)

I have and use two of these, very accurate and I went for this model because of the 9v battery. I also sometimes use the spotmeter attachment which is very useful. For convenience (these Lunasixes are BIG) I sometimes use a very small Sekonic L-208 with an accessory shoe or an Android "app" called LightMeter (by David Quiles) on my phone. Both the Sekonic and the "app" are accurate when I test against the Gossens. Where the Lunasix excels is in its huge EV range. There is another Luna which has an even wider EV range which might be that Luna 3 (III) as mentioned above.

Yes these Gossens are quite accurate. Had a chance to test them on my shutter tester which has a calibrated light source with several EV settings.
Tried to re-adjust my Lunasix III to use with silver oxide button cells but didn't manage to get the lower range right. Guess i must look for another solution.
