JIEHENG Light Blocking Tape 1.2 inch x 98 Feet,100% Blocking for Electronic

I was using the 80% tape for sun blocking on my motorcycle helmet visors, but even two layers let in sunlight enough to be bothersome at sunset. This 100% tape solved this problem. Besides its application is much smother, with fewer wrinkles, and the flat black looks better than the gloss of the 80% tape. For my needs, this tape fits the bill.

Easy to cut and place. Blocks light as well and after many months, still in place doing its thing!

It works—enabled a totally blacked-out bedroom with each true light-blocking materials I used. It covered my mistakes and made it easy. It’s also perfect for little lights on air cleaners, surge protectors, etc. I owe my best sleep to this tape!

The tape blocks light perfectly, but is a bit of a hassle to apply. The tape comes with an inner layer that needs to be peeled off as seen in the preview picture, which greatly slows down the process of taping large surface areas.

I used this to cover the lights in my toddler's bedroom. She was starting to get distracted by all of the lights. It's so nice and works so well. It was really thin when I took it off the roll and I was concerned if it was going to work, but you can't see a thing. It stuck over the round button very easily. My only complaint is that it's hard to get the paper off of the back of the tape. A perforation down the middle or something like that would probably be helpful. But the roll is huge for the price, and very worth it.

This blocks the led lights from tvs and such. I used it on the power packs for my adjustable beds and on the smoke detector in my room. This is the problem. The tape worked well for a while but now it's peeling off after only a few days. It doesn't seem to work well on curved surfaces.

Works perfect

Perfect for blocking blue light coming out of appliances and internet modem boxes.
