Why does every small appliance or useful home electronics item have the BRIGHTEST LEDs in them?
I bought a new fan for our bedroom Sunday. It has 4 speed settings, and LEDs to display which setting you’re on.
Just like every other electrical device in our bedroom, I had to cover the LEDs with electrical tape because they are TOO DAMM BRIGHT. That one light was more than bright enough for me to see in the room with all the lights off.
I can’t sleep well if there’s a lot of light like that, especially blue light, and it’s like every fucking electronics manufacturer used the same extra bright blue LEDs.
All of our power strips have them. Same brightness.
The fans have them.
Don’t even get me started on digital clocks and the plague of bright LEDs that they bring about
Many charging plugs have them built into the plug itself.
Even some fucking light switches have them now!
I have about 6 different things in our bedroom that have electrical tape over their completely unnecessary LEDs.
Why has this become such a common thing? Is this really something most people want? To have a room that is never actually dark even with the lights turned off?
I get to be that guy! I’m so excited!
In power strips, the lights are (in the overwhelming majority of cases) actually a neon bulb! They’re cheaper for that specific purpose because they can be powered directly off of the mains power with a single resistor.
Your point is entirely valid and I bear the same cross, this is just a fun fact you can use to impress colleagues, strangers, and potential lovers, dazzling them with your deep esoteric knowledge of and passion for illuminators in power strips.
Hah, this is what I liked the most about reddit - learning random bits of knowledge about things I knew nothing about. I’m glad to see this happen here too!
What’s a reddit?
It was a website from the old times of the internet, where people behind pseudonyms could freely discuss links and texts inside thematic communities.
sounds weird
Electrical tape to black it out.
Painters tape to dim it.
The electrical tape approach is what I did and it did wonders. Went from having a myriad of green and blue LEDs on my fans/portable AC/etc to complete wonderful darkness when I retired for the night. Made a distinct difference in my ability to fall asleep faster at night. I hate having lights when going to bed. Darkness or bust.
Do this and never look back
May the LED’s I tape not light the way
Car headlight are too fucking bright nowadays
Agreed. I can’t tell when people are driving with their high beams on anymore.
This is why I always have the high beans on when driving my 90’s car. I’ve got to fit in with the cool kids (oh and be able to see the road despite the blinding lights coming at me.)
Not sure if you are joking or not. But at times that’s actually what I think about and sometimes even do. If there is a car with too bright lights coming down the road I’ll turn on the high beams because it reduces my ability to see the road otherwise.
I have a lamp and that has an LED that is on all the time.
Why would a lamp have a permanently on LED? That’s what I get for getting cheap crap from China, rather than premium crap from China.
fun fact: human eyes can actually perceive single photons.
also fun fact: we can shoot single photons.
I have opened up devices to physically remove the led. SMD LEDs stand no chance against a steady hand and a precision flathead screwdriver.
precision flathead screwdriver
Ah yes. Just like my precision printer adjustment mallet.
I don’t know if this is the right place to complain about this but since it’s LED related… Why are all the automakers putting the brightest fucking LED’s in their new vehicles now?? They are legit brighter then how high beams used to be only a few years back!!
What did we all used to do when headlights used to be slightly yellow??
Yeah, there used to be regulations on this stuff, because you kind of just end up in an arms race.
Pretty much the only reason you’d want brighter headlights, is so that if someone blinds you with their bright headlights, you still see things behind that.We’re also in a big vehicles arms race. I’m always telling people about how big vehicles cause more kids to get run over, more pedestrians to die, more damage in accidents, etc. The most common response from giant vehicle owners is that it makes them feel safer in an accident.
In 10 years they’ll probably all be driving tanks with stadium lights mounted on top.
It’s so “Big Brother” can still watch you…?! 😅
Bluetack is your friend. The constant red light on our baby monitor was too distracting in the pitch blackness of the night that it kept my kids awake. A small amount of Bluetack and this problem is solved. Not asthectically pleasing but a good option.
I don’t seem to find it mentioned: LEDs at night are terrible for your sleep, especially the blue ones. Among other things they suppress the melatonin release.
An article that goes into more detail and provides a citations for further research.
Because they’re cheap and look “modern/futuristic” so shit manufacturers love them. I have also used electrical tape on power strips, chargers, smoke detectors, etc
That and your average electrical engineer will consider an LED useful that signals the device has power.
Most probably then don’t consider where the device is actually used. In a well-lit office space that LED doesn’t annoy anyone.
I design electronics sometimes. Generally, people want an indicator light on their product, since it’s a cheap way to show the state of a system.
The main problem is, the human eye adapts to darkness. You can still clearly see an LED in a dark room when a few microamperes pass through them, but then they are useless in brighter light in that case. There’s no specific amount of current that produces light that’s bright enough in a lit room, but isn’t too bright in a dark room.
I can fix that by occasionally turning off the LED and measuring voltage across it (LEDs detect light in addition to emitting it), then dimming it if I’m in a dark room. However, this is quite complicated to do and requires a capable microcontroller and a pretty ninja embedded systems programmer. Most product developers I know won’t think of specifically doing this.
Finally, I can save 0.1 cents (plus board space plus assembly complexity, which cost more) by connecting an LED directly to the pins of a microcontroller instead of using a resistor to limit current. Some microcontrollers specifically allow this, up to 10 or 20 milliamperes, which is enough to be too bright in some contexts already. Margins on hardware manufacture are extremely thin, so optimizing even 1 cent off a board is pretty important.
All of this together leads to a lot of LED proliferation, which I’ don’t like either. The stuff I build for myself often has a way to control the LED brightness, although this would be too expensive to add to a consumer product as a general rule. For small devices, there’s a tilt switch inside that turns off the indicator LEDs if you turn it upside down and hold it for a few seconds. That way you can just reach over at night and fix it without fiddling for switches or controls.
I can understand for things that don’t look obviously on, but a fan? C’mon. If the fan starts spinning, I know it’s working. I don’t need a light telling me it’s on.
I miss the days of red LEDs. I understand blue were new and novel at one point but that’s passed.
new AND novel?
also fresh and different!

The gradual spread of light pollution has gotten crazy, and people still don’t really notice it. We’re at the point that it’s actually driving insects to extinction. If you look somewhere rural vs. urban the difference in what constitutes “night” is mindblowing, and rural areas are getting brighter all the time themselves.
I’m honestly a bit surprised that we don’t have mandatory dimmers installed in all major buildings that turn off the lights after X hour or x number of hours without any movement.
That, and motion sensors and dimmers on street lights with shades on them to prevent light from being blasted into people’s homes and apartments.
This much light pollution can’t be healthy.
A soldiering iron comes in handy.
I just remove annoying leds altogether.
Replace them with a resistor?
I usually just remove it and leave the space empty/open circuit.
It’s very very rare that a missing/nonfunctional led will effect the rest of the device. In those rare cases, swap the light emitting diode for a regular diode (though a resistor would probably do fine too).
