To be clear, I’m looking for a light meter that uses a needle to display the reading. I would love a Luna Pro, as it would literally do everything I could possibly want (it can measure down to a stupidly low light, as well as very bright light), but with my experience with them, it seems like they may not be super reliable. I’m honestly thinking about getting one off eBay, as I have the spot attachment for it which seems very useful, but before I pull the trigger I was hoping to get other suggestions. If any of you guys have a Luna pro and it has worked well for you, or if you have had a bad experience, please let me know! Also, any other suggestions for older style, CdS meters are welcome!
I have rehabbed a number of old Luna Pros to accept modern batteries. They are fine meters, and I still use one regularly to calibrate light on the baseboard of my enlarger.
That said, almost all modern spot meters are considerably better. The Luna Pros exhibit nonlinearity toward at the end of the range. That is, the top of low range, does not match the bottom of the high range. Their angle of acceptance is very wide and the "spot meter attachment" isn't terribly useful.
I do like the Luna Pro a lot and have 3 or 4 of them kicking around here. But when I'm serious, I use a Sekonic 408 or a Pentax Digital Spotmeter (the Zone VI version) for much better repeatability and precision of measurement.
