Light Dimming Tape 1inch x 90 Feet, Black Out Stickers to Block 50%-80% of Light, LED Cover Adhesive Film For Dim Digital Displays, Indicator lamp, Infrared and Glare on Appliance & Electronic Devices

This product is exactly as advertised. Except perhaps the image of the role shows more product than what you’ll actually receive as I suspect that image represents 200 feet.

Humidifier and clock displays lit the whole room up before! Much better nighttime ambiance after this product was applied

It didn’t stick as well as I would like and it’s not as dark as I would like. I keep having to redo certain areas. Wouldn’t buy again

For: Light Dimming Stickers 2inch x 90Feet, Black Out Tape to Blocking 50%-80% of Light Pros: Does reduce the brightness of the LED Width is good for what I needed to do Cons: The plastic film is a little too thin - makes it difficult to apply The thinness results in creasing while applying because the static quality makes it cling quicker than you can smooth it out It sticks to itself better than it sticks to the glass I was trying to stick it on Once it sticks to itself, it is difficult to unstick, resulting in waste Light block varies between 50% and 80%? Is it because the supplier is unsure about how bright the LED is which you are trying to reduce?

Works perfectly! I sleep in my office (big snoring problem), where we have a TV, my work computer, an air conditioner, and the internet modem and router. At night there are blue, green, and red lights everywhere. Not anymore! I put a piece of this tape over every light and now it is pitch black! You can still see the lights if you get up close, but they no longer keep me up at night.

No matter how you slice or dice it, extremely difficult to work with. Do not recommend on glass, not initially stable. I have steady hands and a good eye, but this tape is just tuff to deal with. I bought a couple different sizes, my project lasted three times longer with lots of tape discarded for only 20" of length in each window(4). End result.... ok, not perfect nor great. Will use the remaining tape as regular tape for tie wraps.

It has very poor adhesive properties, and that is why I am rating it only 2 stars. It's fine if I tape it in place with other tape, as the dimming works well enough. However, the fact that I need tape to keep my tape in place is a major negative...I am not going to return it, because it is still better than those dimming stickers that are all of a preset size. The texture of the tape is foil-like and lacks flexibility, which is a downside for using it on an uneven surface, but might be an upside on a smooth surface.

Worth buying, strong and good
