Birllaid Light Blocking Stickers, LED Dimming Sheet Stickers for Routers, Clocks and Electrical Appliances, Blocking Light 60% ~ 80%

This set comes with an excellent variety of shapes and sizes. Even better, they're not opaque, so your LEDs are properly dimmed so they don't light up a room, yet still useful. If you need the LED to be even darker (I didn't), you can double up on a sticker.

Finally no glowing LED lights in the bedroom! These work great!

The stickers work really well for reducing the amount and intensity of light from both my alarm clock and wireless chargers. My only complaint is that the stickers were really hard to peel off the clear plastic sheet. I used tweezers to pull them off successfully. The sticking power is pretty good too as I had to remove them from the item a few times to reposition and didn’t have any issues with adhesion.

I ordered these light-blocking stickers because I need to reduce the blue light in my bedroom. Although I have blackout curtains, I still have electronic devices in my bedroom, like a computer, printer, TV, DVD player, and a clock. Placing these labels on electronic devices helps me to reduce the amount of blue light in my room as I am going to sleep or if I wake up during the night, as is frequently suggested as a sleep hygiene tip. I am finding that I am sleeping more soundly and waking less frequently. The stickers were a little challenging to remove from the backing, but I found that twisting the paper backing and using my fingernail helped.

I’ve mostly used these on electronics in my bedroom with lights on them. I have 2 devices with blue lights that are pretty bright and point right into my face while sleeping I wanted to use these on. I had to use 3 layers of these to stop the light one device from being visible, and 2 layers to make the other device not obnoxious. One sticks didn’t do much. I put just one on the Sonos One in my room and the difference is I can no longer use the light of that like a nightlight. I can still see there’s light coming out of the device, but it’s not lighting up the room enough to walk around by. The cute little designs ends of making them not as effective. Would be better to have more squares and larger circles.

The stickers wouldn’t stay attached and constantly fell off if everything I put them on. Just use tape and a sharpie. Total waste of time and money.

Works great. Can still see through stickers, I doubled up on spots where I didn't necessarily need to see. I used on AC window unit. I put 1 sticker on digital screen to see numbers and doubled up on stickers to block the small circle lights on the settings. AC lights use to light up the corner of the room, now it's nice and dark!

such a simple solution for a major quality of life improvement. I wish they included more of the larger strips. Used it on waterbed heater display and dvr box display. Now I can see the lights without them being distracting.
