@langham I disagree on a few points and will point out why
This is just not true. With a good LED board you can go way past 3A.

The extra 500lumen that a 6A drive deliveres, can be very useful. That you will not find it useful to do, is just your call.
For momentary use, almost any host is big enough. Even a 1*18650 P60 is big enough. A good host and thermal management will help a lot. I made a light that runs an XM-L @ 3.85A and can do this for extended times.
Topic with temperature measurements
Multi XM-L and SST-90 with the dome is just not comparable with a single XM-L in terms of throw in the same host. The SST-90 is by the way a very difficult LED to direct drive of a single cell because of the relative high Vf. Very little cells go past 5A.
True, but single cell operation are mostly limited to X*7135 drivers stacked. Those are small enough.
Too bright? Every application needs a certain amount of light. When my eyes are full adjustment to darkness, the 4 lumen of the low setting of my quark 123 is even too bright. But that just doesn't cut it outside.
There is no "Too bright", only too bright for a certain application. It is imho always desireable to have immense power in EDC size.
This is for everyone to deside. I like high quality and want to pay for it on some occasions.
