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

Exactly what I ordered, just make sure the surface is clean so it gets the best stick. Kinda thin but absolutely block the light, definitely gonna sleep better.

Works perfectly. No light shines through

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.

I purchased the Black Out Edition. While I was thrilled immediately with how well the product worked, how it looked, and the variety of sticker sizes, I held off reviewing because I wanted to see if there were issues with lack of stickiness that others have reported, particularly on curved surfaces like the bulb indicators on some of my electronics. After a couple of weeks now, all stickers have stayed put and continue to completely block out the light. As for the curved surface (bulb indicator), I first cleaned the surface and surrounding area. I took a round sticker that was larger than the lighted area, and then did some snipping around the sticker, almost like slicing a pie, but not cutting all the way to the center. I then firmly pressed the cut sticker to form around the bulb, creasing and pressing it as tightly to the surface as I could. Cosmetically, I then put a second, un-cut round sticker on the top. Worked like a charm. This may not work for everyone or every non-flat surface, but at this product's low price, and a little creativity, it is worth a try. I am a former user of black electrical tape to black out light, but no more; I never liked the residue left by the electrical tape.

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!

When I bought these, I felt that "easy to remove" was a great selling point. And it is. Unfortunately, I failed to consider the other side of the coin. These will only block light entirely if they get a great seal. And, unfortunately, when a bulb is extruding out, rather than recessed, the adhesive that's weak enough to be easily removed is weak enough to be pushed off on at least one side by the bulb. I wasted several of these, as even those 2-3x the size of the bulb were still too weak to maintain an adequate seal with the bulb jutting out in the middle. The smallest round was big enough to provide adequate coverage if the adhesive was stronger, which is why I started with it. From there, I moved to the slightly bigger option, assuming it'd have enough room on the sides to stick. I was wrong. From there, I decided to try a larger square option, assuming that the consistent coverage might help. Again, I was wrong. From there, I jumped to the biggest round option. It still somehow peeled up on one side of the bulb, but it's adequate enough, blocking most of the light and directing the rest out to the side. Still annoying, but better than it was. I get that most lights this product is designed to black-out are recessed. And the ability to remove them easily is important. But I've had Post-It brand products that are stronger adhesive than this, and they were still easily removable. An adhesive on par with something like the Post-It "super sticky" line, as opposed to this would definitely help. Hence, 3 stars instead of 5.

I do not understand any of the negative reviews.. I assume people just cannot read as to whether or not they are dimming or blacking out LEDs. I bought the blackout version because that is what I wanted and it works perfectly. It is a little annoying to apply but not more than any other type of sticker.

The original one and the best for quality and desired effect, block in my case, the power led perfectly.

Premier point positif : la livraison qui s’est faite par voie postale (enveloppe), avec un minimum d’emballage (la planète les remercies). Je l’ai utilisé sur une led clignotante et celle-ci est totalement invisible.

Fait parfaitement le job, je l'utilise pour couvrir la caméra de mon ordi portable et de mon smartphone, et cacher les leds trop violentes partout chez moi. Les vignettes sont ultra fines, discrètes, de bonne qualité, collent bien mais se décollent facilement en cas de besoin. Pour ce prix c'est imbattable on a de quoi tout faire chez soi et en passer à des potes... Allez-y les yeux fermés.

I bought this sheet 5 years ago. these stickers work so well, that I still have the same sheet. I just went to get another sticker for my phone cam because I was putting on a new screen protector and I thought I should leave a review to let you know that this product is fantastic. bought in 2020.... stickers stay until removed. just perfect.
