The only way you’ll get the result you want is if you have a mirror with no loss at all. With any loss, light moves so fast that losing .00001% per bounce will seem instant. Also, if you had this perfect mirror box and the light lasts 10 years, you won’t see anything when you punch a hole in it you wouldn’t see a flash of light. All of the light would leave and disappear far too fast for you to detect.
