From another thread, and perhaps posted in the past, the Surefire Institute videos:

In my experience, practiced flashlight techniques and the tactical considerations due lighting are major areas neglected by many shooters. It is often a case of not knowing what they don't know. That not you? Great. If it may be, even incrementally, then these videos produced by Surefire may be well worth your time.
