With the Class I devices, it's about managing your expectations a little if you're used to standard-power military lasers, you will not get the same functionality.
With the laser-based Class I illuminators, they are essentially "locked" in low power mode with a "medium" flood. On the ATPIAL-C, the focus ring is completely locked, and it's just a "one size fits all" illuminator, you can use the neutral density filter to cut down on the power and give you more of a "fill light," but other than that, you won't get any adjustability on the beam/illuminator (can still be zeroed).
On the Class I DBALs, they have a "high" setting that is the same power output, but they also have another, lower "low" setting. You can also change the
size of the illuminator beam, but it will not
focus the illuminator beam in the same way that you're used to with a military unit, you'll just make the illumination "cone" bigger or smaller, but always the same power.
The LED-based illuminators will give you much more illumination and distance than a Class I laser-based illuminator, but they will come at the price of size/weight and visible signature.
Which will work best for you will depend primarily on what it is that you're doing--the Class I DBALs (minus the D2) and ATPIAL-C are definitely more of a "tactically" biased device, and the illuminator settings are set up to be adequate for ~85% of the situations you'd be likely to encounter in a "force on force" situation.
You do lose some function, however, and the "one size fits all" illumination means that it's rarely "ideal" for any given situation, but adequate for most.
On the other hand, if you're doing more longer range hog/coyote shooting and trying to IR "spotlight" animals, the illuminator is definitely going to seem pretty anemic, and you're likely to be unsatisfied with it, and might be better off with the DBAL-D2.
Then, of course, there's the MAWL-C1 at the cost of a good green phosphor PVS-14... if you can afford it and justify it to yourself, may as well just get that.
