Blackout Tape Light Blocking Tape Black 82 Feet x 2 Inch Blocks 100% of Light for LED Covers, LCD Panels, Appliances Indicator Light, Lamp Strips

Works as intended! Did a great job blocking light from some electronics that was bothersome. Highly recommend this purchase.

This roll of light blocking tape for electrical devices is awesome. Total blackout of the annoying indicator lights on modems, routers, and cameras. Perfect. High quality. Strong adhesive. Would definitely recommend this awesome and useful tape.

I got window film that blocked light as advertised BUT however close against the edge I managed to put it, light intruded along the edges, BUT this tape gave me total light blocking when I put it over the edges of the films and the window frames.If you want a darkroom for developing photos or for no-light sleeping, this tape will deliver with true light-blocking window film.Not all films or curtains that claim total light blocking deliver it. I shop using my bright flashlight to test curtains and films. I found I had to clean surfaces with 70% alcohol and sometimes reinforce this blackout tape with other tape, but it does block light. It’s made all the difference in the quality of my sleep. Without it, the change to dawn light wakes me and keeps me awake.

Thank you!! I wake up at 3am and my new apartment has a LED security light that you can NOT turn off by any means. I’ve begged them to turn it off. So this tape was my solution. Any light you see through my window now is street lights and lights from my neighbors. It’s perfect.

The tape goes on well but with 30 minutes it starts peeling from the surface. I prepped each type of surface well by degreasing, windexing, soap and water scrub, but nothing helped. Each time 20-30 minutes, the tape peels off.

We were hoping to use this on a Pixel Phone 6 Pro along its curved edge to cover a bright stuck pixel line along the edge. It's too stiff to bend and stay stuck on a curved lcd edge like that. If you are looking to cover a flat LCD screen, this would work great.

Works well and we will be getting a better night's sleep without the light.

... the adhesive is so weak!
