RE: Spott Hogg Sight Lite.
Matt:
There are two ways to 'limit' the light output.
1) Put a piece of electrical tape across the face of the light and then put a slit in it to allow just enough light where you feel comfortable.
2) Remove the bulb and 'paint' it with a magic marker. The more layers, the darker, and the more the light is restricted.
In either case you'll have to check your intensity in a very dark room. I have mine just bright enough to illuminate the first two pins when it is totally dark.
Hope this helps.
