It's a super cheap 532nm pointer. I measured the green and it's between 0.5 and 0.6mW, depending how warm it is. Funny how people estimate it at 50 or even 150mW, 100 or even 300 times more. It was getting dark outside and the room was very dark. The laptop had it's screen at minimum brightness.
The funny thing of the picture is that the room looks very normal and lit from outside, but only after 30 seconds of exposure that very little light looks like normal daylight.
Here's one where it hit a light instead of dark material:
Moral of the story: don't trust pictures (unless the exif data reveals all).
Pictures mean nothing what so even because you have no idea what is in the air or the exposure or the cameras own color pickup traits or if they have been edited. If you want to know what 80mW looks like in your air in your house you gotta buy one and find out.
