How well do these block outside daylight? I am trying to find something for a bedroom sliding patio door that will allow daytime sleeping in the dark.

They are great, but not blackout shades and sunlight does come in. You can't see through them and the room is noticeably dimmed, but definitely not dark. There is also space between the panels when looking at an angle where you can see outside.

They are not good as black out shades. The let in filtered light. I would not use these to keep a room dark.

More decorative than light blocking I would suggest blackout curtains for day sleeping

I agree with Brooke. I use these in my office and when I walk in there in the mornings, there's quite a lot of natural light that filters through these.

These are dark during the day ,yet they let just enough like through to see the obstacles in the room. Mind you i never have much direct sun light on mine. They have worked really well for me.

During the day you can see out (not perfectly!) but someone outside cannot see you inside. At night, if you have lights on inside someone outside could see you (not perfectly).

No I installed mine in many window frames. They work great after a year of use. Roles in smooth and holds up very well against the sun too. I was worried they would be too dark but they are a perfect balance. You can see through them just great. I hope this helps you.

Truthfully, have not noticed if it does, but would like to hear from others if the experience has been different. As to their effectiveness during the day and night time, no problem during daylight, but at night time a strong source of lighting is needed for the ones that I have if you want to be able to see anything. There may have been an improvement (?) after the ones that I purchased.

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!

I have ours installed outside. They are under a covered patio and go into a protected portion of the ceiling. Have the installed for over a year and no issues.

It would work great as a privacy screen. You might be able to see shadows through it but that's all. It really does block almost all the sun. We use it on a screened in deck to block the afternoon sun.

I can't say. We live in Missouri and have owned these since early July and they have worked well. Now that we are having cooler weather and more clouds and rain they still work but we've noticed they turn off after midnight and they used to stay on till dawn. So my guess would be that if they get enough sunlight they would turn on in the evening and stay lit till midnight or so, but I am not sure, they seem to recharge when cloudy but not enough to last all night. They look really nice whether on or off.

They should be very good for either. I have used mine mostly outdoors, when the light is low.

I use these lights in motion sensing mode. There is a mode for dusk to dawn also. I don't on how much light you are looking for. I do enjoy them. I do need replacement batteries for down the road. Hope this can help you. Adam M

Hi Mike, Thanks for your question.The window have zip up covers that should be helpful for darkening at night.

We use our shades to block the morning sun on our covered porch. I don't know if you can see through them at nite.

They do a really good job of blocking out light. They also do well at not touching my eyes while I'm sleeping either so I think it might work well for you too.

no this won't block out sunlight or shade the room. Check with Gilla brand for solar window film

I've worn these at burning man. They block dust well and look pretty cool. They are also very dark, which is helpful for the intense sun during the day. However, I am not sure if they are uv rated (I think maybe not) so I often wear uv rated sunglasses instead. Can someone please confirm the uv rating of these?

Our windows lead directly outside, and we placed thin sliding doors on the outside over screen to close the area when we leave or if it rains.I don't know if that would work with a sun room.

I think It does. Mine are not exposed directly to the sun and yet the room is not dark. Other reviewers say that in a window facing south, It blocks heat and sun
