Blackout Tape 1.2 inch x 66 Feet Dark Masking Stickers to Blocking100% of Light, LED Cover Shading Tape for Windows, Electronics, Blinds, Aquarium, Indicator, LCD, Routers, Lamp Strips, Dimming Sheet

This is excellent blackout tape. Not a single LED device I have put this on has any visible glow. It is PITCH BLACK. It is quite surprising given how then the tape itself is. It is very easy to apply, works exactly as described and is VERY sticky. I have no worries of the tape falling off.

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

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?

We used this tape to frame our windshield as the factory installed edging had deteriorated in places. Now our windshield looks like new. Easy to apply

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

Good for the little lights on large and small appliances. Hides the light on our smoke detector, fan and humidifier. Worked great on the TV in my hotel room. I always bring some with me on my travels. Sticks well and is easy to use.

This tape is awesome! Wish I’d discovered it earlier. It easily blacked out the annoying glow from a couple power strips in my bedroom. It doesn’t have a strong adhesive. It’s almost like it’s held on by static. So it should be easy to remove. You cut the size you want, peel off the backing and place it where you want it. I’m going to start packing some in my bag when I travel since there always seems to be little lights in the room that bother me when I’m trying to fall asleep.
