LightDims Black Out Edition Light Blocking LED covers (2 Sheets) Shapes & Uncut Sheet for Electronics & Appliances. Blocks 100% of Light, in Retail Packaging.

Just what I was looking for!

They work great.

Blocks light as advertised. However there is an issue when attaching to a slightly curved surface. I cut a 0.75" by 3" piece to cover the elongated lighted section of the front of my router which has a very slightly curved body. The blackout material is somewhat stiff. The center section stuck to the router but the ends that follow the curve of the router body eventually sprung back to their original straight shape. I can re-press it onto the router but it eventually comes loose again. It works great on other products that are flat. Using fingers to try to place small pre-cut pieces takes patience. Using a tweezers to hold and place those small pieces is much easier.

When these arrived, I didn't waste any time applying them. My desk is where my desktop and several other devices reside, each with it's own annoying LED. There is, however, one LED on my computer tower (on top of which I keep a desk lamp which I use all the time when working at my desk) that is so bright that when I approach my desk in the dark room to reach up and turn on the desk lamp, I have to cover that light with my hand in order to be able to see enough to find the lamp switch. When I walk into the room at night where my desk is, I am reminded of looking down while flying over Chicago at night, there are so many lights. So I couldn't wait to test these blackout dims, and you guessed it, that big blue CPU light was the first to go. You should've seen the smile on my face as I saw the light just disappear. I quickly proceeded to cover the rest of the LEDs, and now walking into that room at night is a whole different experience. And I don't get why some commenters here are saying that these do let some light through - I haven't had that issue at all. And I didn't have to stack any dims to get the job done.Also some have said that you have to be sure to apply the dims exactly over the light, as they are not removable to re-apply in the correct position. I didn't experience that either. I did use a tweezer to grasp a tiny edge of the dim to assist in placement, and this worked great. And when I did apply it off-center, it was no trouble at all to remove and re-apply. In one instance I applied a small circle, found it was slightly too small, and removed it and placed it back on the sheet for another time. I can't think of a single thing I could possibly have against these dims. There are more than enough on this 100-sticker sheet for my own use so I can share with a friend. I will gladly recommend this amazing product to all.I am impressed with the company also - it's a small family-owned business, a husband/wife/2 daughters. They were right on top of my order, and I received it BEFORE the range of estimated delivery dates. They also included a free gift, which was a dimming sheet that fit perfectly over my Kindle Fire after simply trimming off about 3/4" from one end. Now I don't worry so much about using it in bed at night. The company also promises a steep discount on a bulk purchase when placing an order directly to them. I ask you, what more can one ask? GO BUY THESE!

The media could not be loaded. These dimmer stickers are SO helpful. I got the full black out variety and they fully black out the annoying/intrusive light. The video is of my alarm clock which has a blinking center colon to count off the seconds, and it drives me UP THE FREAKIN WALLLLL. I’ve always had the clock face toward the room rather than me which means I either have to get uncomfortable again to look at the time, or check my phone which inevitably leads to me staring at the phone for too long. Since the numbers and symbols are under the surface glass of the clock a bit it was a good example since you can still barely see the covered light from a steep angle and know how blacked out the lights are. I’ve also used these on several pieces of tech at work - in fact before I knew these existed I took a hole punch to some electrical tape and made a “dimmer sticker” for my old office phone (if only I knew there was a business in that!!). These are less tacky than tape so it seems like they won’t leave marks if you remove them which is great, and come in a variety of convenient sizes, such as the exact size of my monitor buttons at work.I also think it’s great that this product was born in the US and I hope the creators will be able to bring the manufacturing home soon, or at least are making sure their Chinese factory is one of the ones that doesn’t use abusive labor!There is no flex to these stickers and my monitor buttons are slightly indented, so I’m not sure if they’ll stay or fall off, but these last two points are really my only complaint. I don’t love that everything besides the stickers is 100% plastic, but maybe it’s to protect the adhesive for transit and storage? Maybe hemp plastics could be used the the future :)
