How about the widest single unassisted metering range of EV - 6.5 EV to to EV +20 that is unequalled by any camera past or present. Couple this with realtime monitoring of the scene - making adjustments accordingly, and aperture auto exposure for as long as it takes or battery dies and it is the right tool for night shots. I've tested both of my LX's and they meter nearly identical for exposures > 2 hours in a controlled setting.

I don't know of an external meter that can match the LX's single metering range.
