Holosun IRIS-3 vs Steiner DBAL A2 (PEQ-15A)
Both on Dual IR Laser/Illuminator Mode Illuminators on both units were focused at their widest divergence without the use of diffuser caps (neither have any right now anyways).
Dual Low Mode:
Steiner DBAL A2 Holosun IRIS-3
Dual High Mode:
Steiner DBAL A2 Holosun IRIS-3
It really is quite amazing that a $900 civilian laser can match the performance of a $1,500 full power military laser, all with smaller form factor, better control ergonomics, and a full warranty to boot.
Obviously not the "best" laser on the market, but if your only goal is getting similar capability as 'fell-off-the-truck' FP MIL/LEO units, within a lower price bracket, without buying lasers from less reputable companies, the IRIS is incredibly hard to beat.
From where I was standing, I believe the treeline was around 200-300 yards away, if not more (I'll measure it later). Phone camera through my NVG's obviously looks 1000 times worse than the naked eye, but both units performed roughly about the same.
The IRIS's VCSEL illuminator is definitely much cleaner than the DBAL A2's EEL-based illuminator, and a bit more visible on low power than the latter.
The dreaded 'ring' artifact that initial IRIS buyers were reporting is also not present on my unit in both wide and small cone divergence.
Now everyone go bully Villain Weapon Systems to make a diffuser cap for the IRIS.
