How well does this block out light (e.g. if room lights are on)?

It blocks out light very well. The only thing is, if you have cats, do not buy this. Our cats tore it up. but yes, it does block out light really well if you zip up both sides.

It is amazing and gets pritty dark it only gets light enough for u to bairly see when lights are on

If all sides are zipped, there's virtually no light coming through. I made a "makeshift" projection screen out of an all white shower curtain and hung it on one end of the tent and watch movies on it with the mini HD projector I bought for my iphone. I bought mine for privacy here in Afghanistan, but I probably won't take it back to home due to the dust over here, but I will definately buy another bigger one when I get home.

It blocks out some light, probably not enough to sleep with lights on though.

It works great for blocking light. It would be great for someone who has to sleep during the day or shares a room with a night owl. Wish I'd had one of these in college!

It's not pitch black but its dark enough to nap during the day or sleep late into the morning for me. I am pretty sleep sensitive as well. Best they I have bought for college. You have to leave a vent open when you sleep though or it gets musky. Not a big deal though

Ours is in a dim hallway with no direct natural light, and it is off during the day. It only comes on at night when none of the bedroom lights are on and the hall is dark. It does exactly what we wanted it to do.

Light? A fair amount. It comes exactly as you see in pic so plenty of light is able to get through on or off.

It blocks out maybe around 15-20% of the light from the screen when viewed perpendicularly from the screen. Its main use is to deter nosy eyes from the sides. If 15% reduction of glare from the screen is good enough for you, then it probably gives u a 2 in 1 deal. ;)

The room has to be very dark. No lights outside lights should be no problem if you use a translucent curtain or shade. The light needs to be facing the shade so it can iliuminate the shade. Timer is ok if you leave the switch in the always in position.

Yes, it does block well for privacy. The light shines through but it is diffused and cannot be defined from the outside. I am very pleased with the results for privacy issues.

It seems to block light pretty well overall. Sometimes there is a little that creeps in on the bottom, but usually it is just a matter of pulling the mask down a little bit more so that it is sitting right. I can't promise perfection, but I haven't found anything better yet.

There is one light on top of the fan that you can see faintly on the ceiling of the room when lights are off. It is not very distracting at night, but it can easily be fixed with a small piece of tape if you prefer complete darkness.

Good if there is a lot of light. Not too bad indoors - the VR lens helps so it's better there than those without.

Light will come through somewhat, but it is diffuse. This is more of a privacy screen, and light will also show over the top, especially if you have an overhead light.

Yes. It completely blocks out the light.I hang it in front of my garage window.

No Richard. My experience is it will not do much to diffuse bright light at night. The product is very effective in blocking vision into the home in the daytime, but at night it is the reverse. It allows everything and everyone a clear sight line inside the home. If you want to completely keep light out of an area, I would suggest blackout curtains. I've use them for years because I am very UV sensitive and they block 95% of daytime light and 100% of night light. There are many styles, sizes and price options are very reasonable, they work, and they really help to reduce heating and cooling cost. Hope this helps. Elaine

It blocks out the sun great- you may want to remove it in the evening if you need to look through that window for turning out on to a street street see if cars are coming, that's my only complaint: In low light situations before people put on their lights, it is tough to see through

Yes, you can see the light. It is blue and I don't like it at night, so I just turn the light off, but keep the air purifier running. It works best in room up to 13' x 14' or 182 square feet.

the fixture's lens does let light through but only supports a maximum of two 60 watt bulbs. I used two 14watt LED bulbs equivalent to 75 watt incandesent bulbs and it lights up the room fairly well. My room is 13x12, the fixture is on the wall 6 feet from the floor and 3 feet from the corner. For good reading you need to be close. There are too many shadows, it is not like a ceiling light.

I have an east facing window in my sons room that wakes him up at first light. Would this block enough light?

No. I actually got it for the opposite reason. I wanted to allow light into my place without sacrificing privacy and it does that quite effectively. If you are looking to darken a room, this is not what you are looking for.
