IOR has a few scopes that have great illumination. The new 2.5-10x, the hunting 2.5-10x, the new 6-24x, and the new 3.5-18x.
All the other IOR scopes illumination sucks big time, including the one you are asking about The optics are very good and they look good in low light, but the illumination is so bright even on the lowest setting that it lights up the entire picture with a red glow. If you are after a great low light scope, look at Trijicons line. The glass is not quite as good as IOR, but because of the very good illumination system, they are a better low light scope.
