The better beam is a function of the size of the reflector. The small DX P7 lights tend to have small reflectors. Unless they start using aspherics those small lights are always floody.
Aurora used to make a little 1*18650 P7 with a huge head. I think Trustfire still have a little body big head listed. But if you are willing to put up with a big head why not just get a big light.
I'm really confused about your beam pattern analogy. If you can get a good beam from the Mag, why couldn't you with an even better quality light?
The Nitecore EZAA is 135 lumens on max not 400+ lumens. It falls under the category of my last paragraph - going from the car to the house, looking for things that rolls under the table, going to the bathroom in the middle of the night. Each usage is usually a minute or 2 and on low. It does not get used for search and rescue where brightness and throw and runtime are important.
The Nitecore EZAA runs for about 40 minutes, it's not made for runtime, yet they still sell it.
Most powerful lights need the power of lithium batteries (or a ridiculous number of regular batteries). But they have reached the point where even CR123A and 18650 just won't do the job. Now we have to use IMRs and 26650s. But that is within CPF and among other flashaholics.
Remember big companies cater not to CPF, but to the general public and specialists (police, fire) where lithium batteries are not well known. Fire needs hazardous approved lights and lithium batteries just love to explode.
There was a thread where a small company imported and sold some very powerful lights using CR123A batteries. There were some battery explosions and someone reported to the correct proper authorities. The government ordered a full recall. The company had to refund the purchase price and destroy all the dangerous lights. Lost a lot of money. So most companies that sell lights in the USA are very careful what they bring in.
DX don't care. They are not in the USA.
The Eagletac M2 runs on 18650s and CR123As, yet people consider it a good light.
The EDC-P7 is a 1 mode light. I can not switch to low mode.
I got the 30-45 minute runtme estimate from making 4 breakfasts - boil water for instant coffee, make sandwich over 4 days - before the light starts to dim. It was not a single continuous run.
The heat... Well, I'll admit it can get to be too much, though you can always switch into med mode for a while, but I see your point.
And now you're saying that it's a 5 minute runtime, after stating yours has a 30-45 minute runtime? Also, take into consideration that a light made by a better company would actually have a driver, with better slightly runtimes. It's much easier to carry a single cell light with an extra battery, then it is to carry a double cell light anyway.
As to quality companies that make 1*18650 P7/MCE/SST50 lights, some do, just not all of them.
Wolf-eyes makes the Sniper and Explorer.
Dereelight offers MC-E in many of their models. The CL1H V4 3SM Cree MC-E (OP) is probably the most compact.
Lumerpower has a slew of D-mini models.
Olight has the Triton and Warrior models.
Shiningbeam has the MG P-Rocket.
EDIT
I forgot to mention Peak LED solutions, but jabe1 already did.
