Fenix L1P compared to LOD?

I wondered if anyone out there that owns both of these lights can tell me if the LOD Q4 is noticeably brighter on its highest setting than a smooth reflector L1P that is rated at 46 Lumens? I don't mind the extra size of the L1P, but if the LOD is quite a bit brighter, I would probably buy one. I don't have any AAA lights, just several AA ones, but am intrigued by the AAA ones. I know the LOD is rated at quite a bit more lumens, but I know sometimes that is misleading compared to how a light looks in the real world, so please let me know what you guys think.
 
From the numbers on Flashlightreviews, the L0D-CE(P4 version) has 400 lux at 1 meter on high and the L1P has 650 lux at 1 meter. So the L1P will throw more then the L0D-CE.

But the L0D-CE has 65% more output then the L1P on high(to the eye this is around 25% brighter).

From that info, the L1P has a narrower, throwier, but dimmer overall beam then the floodier but brighter beam of the L0D-CE.

The Q4 version of the L0D-CE should have around 500 lux at 1 meter and around twice the output of the L1P.
 
My L1P got modded long ago to a Soul P4 so it's about twice as bright. Fenix lumen ratings are probably somewhat optimistic, but I can compare my Fenix L1D Q5 at the 40l setting to the L0D Q4 at max, 75l. Yes, roughly "twice" as bright.

The L0D Q4 is quite an improvement over the pioneering L1P, with multi-modes, more efficiency, and it's a nice small package. You lose a rear button, and the lower modes use a PWM that makes them strobe-like. Mine is also a bit on the cool blue side.

The medium and low may not be too accurate. The screen of my camera was flickering even though I do not notice it looking at the wall.

The major advantage of the L0D is the strength of the spill. The L1P will put a spot at a distance and the spill lights up my immediate area with dark in between. The L0D lights up every thing in between as well.
 
I had an L1p and a regular L0D CE (not the Q4 version). The L1p was a tad brighter and had a more focused beam, and I preferred its simpler UI. But it was also quite a bit bigger, enough that I preferred the L0D for EDC purposes unless AA battery interoperability was important. Of course, a Seoul modded L1p would be much brighter still.
 
My measurements show that the total light output from an L0D CE at maximum is just about twice the total light output from an unmodified L1P.

However, the L1P has about 1.8 times the main beam brightness (lux at one meter) than the L0D CE, which means that an object at some distance from the L0D will be as bright at 1.35 times that distance from the L1P. This means the L1P has a more tightly focused beam, which should be no surprise because of its larger reflector.

Like a lot of other people, I've modded an L1P by replacing the Luxeon emitter with a Seoul P4. The result is twice the total amount of light, and 25% or more increase in the main beam brightness -- depending on how much you fiddle with the focus --, at essentially the same run time.
