This is a shot of the GL80L tent with the room lights off. The bottom of the tent has the passive vents open, thus all of the light. You'll also see where I have circled pinhole light leaks in the stitching, and the bottom zipper lets out the most light. None of this bothers me as the fan is so loud I'd have to turn it off whenever anyone comes over! I see much less light coming inside the tent.
