I just recently switched to the Cosmic sight and it was quite bright, but that was with snow on the ground and a full moon from a treestand. I'm hoping it works im my T2 I haven't tried it yet. What I liked about the Impact Archery sights is the ability to add a light onto the sight, which would work real well inside of a portable blind, especially a Double Bull. There quite dark inside.

The only problem I noticed with the Trophy Ridge light sticks is that they don't last all that long and there not cheap. I could go through quite a few of them in a week long hunt from a Double Bull. The battery for the Cosmic will be much cheaper over time I do believe.

Good Luck
