Not sure what I was expecting. But it does not seem as bright as I thought it would be
That M91 does seem to be really lighting up the entire room - the P90 is only satisfactorily illuminating one small spot.
An M91 is a 'floody' design; they never do look quite as impressive as the one small bright 'spot' of a thrower - but is far more useful for most applications.

A bit of history for context:
When Malkoff went from the M60 to the M61/91 models, one revised component was the new reflector design.
The newer series has considerably more flood; many (including me) has found these much more useful for general use - this of course reduces the 'spot' intensity (i.e. maximum lux).
The 61/91's do not have quite the reputation of the 60's (or other larger-reflectored dropins) for 'throw', and did receive some small initial criticism
in this specific aspect before getting general market acceptance as being a substantial improvement over the 60-design.

Edit: The way I have looked at it:
- My prior car flashlight contained the M60LL; an adequate hotspot with very little spill. Fantastic runtime.
- I replaced that dropin with a higher-output M61L; a comparable hotspot to the M60LL but with much more spill - far more useful IMO. All of the increase in output of the new single-L went into the spill, not the hotspot; with a modest loss of runtime.
Edit #2: A comparison to the P90 that you're doing is a bit of a tough one: the P90 incan lamp assembly was a pretty epic bulb for its time - on fresh cells, it will have nearly
double its listed output, IIRC.
