One thing a lot of people overlook when getting an IR light is the ability to move and point to light to the center of your screen view.
Lots of those lights just mount in a scope ring, and where it aims is well... where it aims.
The lights I use have a ring mount that incorporates a swivel type adjustment. You tighten the beam down to the brightest square, then move the light to be in the center of your field of view, then tighten the mount down until it's ridged.
When you want to see more than a couple hundred yards, you can tighten the beam, and see much, much further.
Another plus, is the ability to tighten the beam when hunting in brush, and not be getting whiteout in your scope from reflecting light off of brush a wide beam light may be hitting.
Sometimes you just get what you pay for.
If you want a wide beam and only be able to see 2-300 yards, and hunt in open areas where whiteout from brush isn't an issue, then you may not need a better light system.
I can see much further than I can shoot...Clear view out to 800 yards or so. And can tighten the beam to not get whiteout when shooting down senderos, or ranch roads.
To me, after trial and error, it would be like mounting a scope on a rifle without sighting it in. Just because it is pointed in the same direction, doesn't mean the light is hitting center of view.
