It can definitely light up your campsite. It’s dimmable, I used mine to shine light on a park size bench for dinner. Lights up the entire interior of a tent. This can also charge your phone. 

This is more a question of your glasses and not the lamp. She produces light. If your glasses have an anti-reflective coating, the lamp will not be reflected in the glasses, depending on the level of anti-reflective coating. (It should be noted here that the anti-reflective levels trigger different colors, level 2 triggers a blue tone in the glasses, level 3, which is the most recommended for working on the PC, triggers a green tone. This goes badly with a green screen , if the plan was to connect this to it) 

Yes, it can run indefinitely after being plugged in. 

Of course you can, it is highly absorbent and you can stick it to any smooth place such as walls, mirrors, computers, iPads, desktops etc. 

No. I bought it based on the claim that it would support the weight, but it doesn't. However, i have found that if I don't try to use the cantilevered function, but just use the height of the combined tripod and arm (straight up) and the ball joint holding the binoculars, I have more than enough height to see anything up to about 75 degrees comfortably. In the video, the eyepieces are at 6', and there is easily another foot of extension available.
