You don't find the 9V too much for indoors?
no. or rather, not yet. most of the walls in my house are darker with lighter ceilings. i can light an entire room with a flash of the light on the ceiling (yes, i know bad muzzle position for efficient mount of the rifle), have more than enough light for most anything else on my property.
i really like rhino's idea for the multi power 9v led. run it low/mid indoors and throw it wide open when you need it, like outdoors. i wonder if clyde and the folks at first light could make something like this....
