I haven't noticed an answer to this one, so I'll ramble on about it.

The equivalent of lux is foot-candle, also called lumens/ft^2. As lux
is lumens/m^2 the conversion is simple: 1 foot-candle is 10.8 lux,
though most of us just call it 10.

Yes, cine meters, including the cine version of the 508, often measure
in lux. However, it is easy to convert.

With the meter set to EI 100, and used in incident mode, for most meters:

Lux = 2.5 x 2^EV 

Best,
Helen
