Aster Light Blocking Stickers - 3 Sheet Dimming Tape for Electronics, Blackout Sheets for Led Lights (Black and White)

These stickers work very well. I bought them to cover up thr devices in my bedroom such as tv and wireless charger as they were disturbing my sleep. Easy to apply and long lasting. Remain sticky for ages (months and counting) takes away all brightness completely. Range of sizes for whatever you need. Excellent value for money would recommend these to anybody.

I bought these to dim the light on a digital bedside clock. There's no dimming, just complete blocking so you cannot see the time at all. They are horrendously sticky and difficult to remove. I gave two stars because if you wish to permanently blackout a light they're ideal, but if you want to see any indication as to whether a light is even on, they're awful.

These stickers block out, not dim, LED lights. This is not a bad thing, but ensure you are looking to block the light completely, rather than reduce it. They were very easy to apply, and about the only one I found with circles that were beyond an inch in diameter. It came with there sheets; shiny black, shiny white and subdued thicker (felt like) grey/black sheet (which wasn't part of the description, that I recall). Did the job lovely on a pair of Lacie 1big external Disk Drives which both have a big blue orb LED on the front. The photo is with the drives on, so normally with a very bright blue light.

Great selection and works well at keeping the lights out! Perfect for my aircon

I have a very bright blue light on the air purifier in my bedroom. Even with the "no lights" option of the device the blue light to show it is on is still illuminated. I have been using white tape for a while, which has dimmed it, but not blacked it out.The stickers come with a thick silver colour backing, which with one sticker only dimmed the light. I ended up layering them and by the third sticker the light would not shine.While not needed I also tried out the black sticker on another led light on a router for testing purposes. This worked perfectly with just one sticker.

I ordered these hoping to DIM the light on my aircon machine (as described in the item name). However, they don’t dim…. They completely block the light so you are unable to see the screen. They are really thick instead of a film like I assumed it would be. So completely pointless purchase unless you want to BLOCK the light instead of DIM!

These are light blocking stickers in black and white. The listing does say that it blocks out 100% of the light so I would presume you wouldn’t see any light all. That’s exactly what I wanted as lots of things have flashing LED lights saying they’re working but no option to turn the flashing light off.I have Bluetooth ear defenders and when it’s working the light is flashing but now there isn’t any light showing. I’ve also got a dashcam with an unwanted flashing light that these stickers will fix.They’re mixed sizes so can use one or multiples. The value for money isn’t bad compared to how many you get. The only thing I’d say is that they’re thick and very sticky so make sure you get some sticky stuff remover in case you want to take any of them off again.
