2pcs Light Blocking Stickers, Light Dimming LED Filters for Routers,Clocks and Electrical Appliances, LED Covers Blackout (White)

They do what they're supposed to.

Usati per coprire i led di un router in camera da lettao che mi dava noia di notte. Non bloccano completamente la luce, ma questo è un bene se si vogliono comunque tenere sotto controllo le spie e il loro funzionamento. In caso si voglia coprire al 100% basta incollarne un paio uno sopra l altro. Non capisco sinceramente le recensioni negative.Consegna Amazon Prime come al solito veloce ed impeccabile.

These block quite some light.. I would gamble above 50% but below 100%.. If I had to estimate in effect they'd be about 70-80% light blocking, which is genuinely really nice.. These did the job blocking light on my router and my wifi extension points etc. All in all very satisfied

Très bon système pour camoufler toutes les leds dans la nuit.

I have used black light blocking stickers to cover up annoying flashing LEDs on modems and other equipment. I found them totally effective in blocking light ..….but a little unsightly on white equipment. I have been meaning to buy these for some time and read reviews which suggested that they were less than effective at total light blocking. Nonetheless, went ahead with the purchase ………and discovered that those reviews were accurate. I have doubled up on the stickers but light still passes through. Still, on the positive side, the white equipment looks smarter with the replaced black stickers being overlaid with these white stickers!
