It's an emergency light. If there's a power cut/fire this light will come on so you can see. It's battery powered and the green light means it's working.

Source: I have dozens of these in my building.

They do exist!

You’ve definitely given us enough information to make a decision. This is actually an alien probe.

[–] [email protected] 9 points 9 months ago

It'll be a tight fit but I've shat bigger, so they should be able to make the other direction work... I believe in aliens.

Come on now, nobody wants to watch you poo from above.

The real creep cam is just under the rim. You get the best view from down there.

You've done well in relaying this experience/knowledge unto us

Edit: also prolly where the term "rimming" came from [Chef's lick]

It's a night light, so if you go to the bathroom in the dark you don't miss.

The human eye is the most sensitive to green light, so the least amount of light is needed for you to be able to see things. Green lights are excellent for night lights, due to this reason. You don't lose your night vision, and you see more detail.

Humans have best retina stimulation in blue light, not green light.

The real reason I suspect the light happens to be green is that green phosphor is relatively inexpensive.

Blue light could be disruptive to circadian rhythm while green light is somewhat less so, but I guarantee this was not part of the calculus here. It is just being thrifty. Circadian rhythm benefits are just a happy accident.

When fully light-adapted, the human eye features a wavelength response from around 400 to 700 nanometers, with a peak sensitivity at 555 nanometers (in the green region of the visible light spectrum). The dark-adapted eye responds to a lower range of wavelengths between 380 and 650 nanometers, with the peak occurring at 507 nanometers. source

[–] [email protected] 4 points 9 months ago

From that source:

At threshold sensitivity, the human eye can detect the presence of about 100-150 photons of blue-green light (500 nanometers) entering the pupil.

So I guess either blue or green leds are good for this application, and green much cheaper…

I will just say that the recent video from Veritasium about night vision goggles does indeed say that you see better the blue light in the dark rather than the green.

And that's why high end military grade night vision goggles are in the blue spectrum.

Wut? Blue? Are you sure about that? Afaik the peak is around 555nm, yellow green. Why do you think we have "high visibility yellow" vests and not "high visibility blue?"

IIRC 555nm (or whereabouts) stimulates the L and M cones simultaneously.

[–] [email protected] 3 points 9 months ago

Light vs dark adapted. In bright light, the best wavelength is longer.

is this a serious answer or

[–] [email protected] 32 points 9 months ago (1 children)

You tell me. You're in the room. Is there enough light from that green light to navigate safely at night?

[–] [email protected] 15 points 9 months ago (1 children)

It’s been 3 hours. OP has definitely fallen into the toilet while checking if there is enough light.

If he starts seeing babies crawling on the ceiling, then it's time to quit.

[–] [email protected] 5 points 9 months ago

This is such a cliffhanger. I need to know, is it good enough to see or not?

This is Sam Fisher clinging to your ceiling.

gasp ive been plundered (if it acrjallt did id cry)

There are only 6 Google results for this "word".

This thread is #6.

Emergency light, so you can see when doing your business in the middle of the night. Fun fact, a large number of accidental deaths happen in the toilet.

Is this a new thing? Why green and not red?

[–] [email protected] 6 points 9 months ago

I'm pretty sure that's just the OG Xbox boot animation.

Nightlight?

[–] [email protected] 2 points 9 months ago

Is it on the ceiling? Maybe attached to a smoke detector? Can't really tell anything from the photo.

The heilwald loophole just appeared in this dude's room bro
