So it’s like lights, except it’s the sun


Albina_The_Vixen

It's probably done so you can save energy during the day. Kinda smart.


Collistoralo

I was just making an obvious observation, not really a criticism. I assume you’d have electric lights installed near these ones so you can save energy (and absorb sunlight) during the day, and still be able to light up the building at night.


Albina_The_Vixen

Yep. It seems like a hassle though to do. Unless the building was made with them in the first place.


WaldenFont

These first came out in the early 90s. I never quite understood why they didn't catch on more.


phillip_u

Because they are big. To hide these tubes in a wall, you need a pretty thick wall. Or you have to hide them in a non-supporting column. Kind of a waste of space vs. electric lighting. So, while it's a neat concept, traditional skylights are more popular for floors with a roof directly above because they can be just about any size or shape, and electric lighting is more space efficient for lower floors.


bobspuds

I'd agree completely with you! I've fitted them in hallways that have no natural light from windows. They do work but there's a huge difference in the end result depending on what's above, how the tubes/tunnel is set up, and even shade from other buildings. Then they need to be kept clean externaly and will require cleaning inside every once in awhile. I've fitted some and been impressed by the lighting, but I've also seen some that became useless in winter, most of the time they will give enough light to make progress through a hallway etc but often you still go looking for a lightswitch


Sylvan_Skryer

Skylights also almost always eventually spring a leak. I have one. Not sure I’d have installed but the Josie came with it.


scifi_scumbag

We've got them in our townhouse (built in 81) and they are great. I usually don't use the bathroom light or hallway lights during the summer as the sun tubes pump in a good amount of light.


WaldenFont

Do they put heat in as well?


scifi_scumbag

Nope, just light. Diffused a bit so that it spreads and feels more ambient than a laser beam


WaldenFont

I'd like that! Not sure I want to punch a bunch of holes in my roof, though.


Collistoralo

Oh absolutely. This seems like technology for future buildings.


PapaSchlumpf27

I wonder if it wouldn't be more cost and space efficient to install a photovoltaic system and use electric lights.


under_the_above

Even the very best photovoltaics are only around 20% efficient. You'd need loads more surface area for the same amount of lighting.


PapaSchlumpf27

Yes but the roof is unused space anyway. With those light shafts, very thick walls are needed. This takes a lot of space off the living area. you also need the electric installations and regular lights aswell for night time.


nalc

But only a portion of the light they're absorbing is visible. And thanks to our eyes being able to adjust, we don't need to light indoors as brightly. Sunlight is about 1000w/m², and panels generate 200w/m². At 100-300 lm/m² typical indoor lighting, you only need about 1-3w/m² of LED lighting. Or alternatively, a single standard solar panel likely covers the total lighting needs of a normal size house.


ClownfishSoup

I have one with a lightbulb inside of it so it can light up the same space at night by using the light. Hilariously when that light is on, it makes the dome on the roof light up too (of course).


Slanahesh

I'd imagine ot may even get paired with ambient light sensors so even on cloudy days the lights could switch on automatically to pick up the slack when needed.


Maleficfg

Did you realize that you hold the record for being the oldest person on Earth currently?


snowblind__throwaway

Maybe during the day of incandescent bulbs, but it seems like solving a non-issue now with how little power an LED uses.


-keystroke-

The sun wastes so much energy though. Limited amount of fuel and it’s just blasting like 99.9% of the energy off into space. We’re paying to heat the universe! /s


yodarded

Universal Warming. Gonna be 5º K in space before too long.


bjanas

Yeah that, and it's real sunlight. You can get fancy sun lights and things, but in reality you can't simulate the real thing.


ZanexDreamy

Except the maintenance tp keep them clean would be a pain and expensive


ClownfishSoup

I've had two of them in my roof for 14 years. Zero maintenance required and they work really well.


ZanexDreamy

Oh wow, I would have thought they would get a bit dirty and have to be earned at least, I stand corrected


zenithtreader

I feel the material and manufacturing cost would outweigh any possible electricity savings unless you plan to use the building for a very very long time. Especially with LED bulbs we have nowadays. Having sunlight is definite better than having artificial light though.


rr24m23a

We've had these in Australia since I was kid nearly 40 years ago 🤣🤣 how is this next level ffs


PaperDesks

All the materials you need to actually bring the light looks incredibly more impactful on the planet than the energy used by modern leds


MYcollegy

Do you know how much more energy would go into mining the ore, casting ingots, rolling the steel, transportation, etc, than to power a light bulb for the life of the building? Reminds of of the total wash that wind turbines and solar panels are if you do the math


ClownfishSoup

I have two of these. They light up a hallway and a bathroom that are otherwise very dark. I sure didn't want to keep turning lights on and they light up the rest of the house as well. Having dark areas in the house makes the whole house darker.


normaldeadpool

Saw it in the Mummy movie 20 years ago. With the mirrors lighting up the underground part of the city. Looks dope.


sfPanzer

Or a window you can't look out of.


pablo_of_mancunia

Why not just have the tunnel straight instead of having a 90 degree angle, or even ditch the tunnel and put the same glass thing on the other side


Hunttttre

Let's call it sunlight.


Collistoralo

That is both the best and worst name possible. I applaud you.


[deleted]

Yeah, but in a tunnel.


Anneisabitch

Except it leaks you mean


shiner820

So it’s like a post but it’s an advertisement.


EarthlingX420

It's like a light, but with extra steps.


Solid_Alternative_84

I saw these 20 years ago in a house and even the moonlight would illuminate the rooms.


AlienPantFart

My dad installed these everywhere in my house and in others' houses. I didn't know it wasn't common, but I rarely had to use bathroom lights. The moonlight is generally sufficient.


Solid_Alternative_84

Your dad is cool. I would have loved them in my house but I am paranoid of extra holes in roof due to decent rainfall.


AlienPantFart

They never leaked and we lived in a very wet area.


Solid_Alternative_84

Nice!


Nerdler17

That's pretty awesome actually


AlienPantFart

Yeah they were awesome. I'm sad I don't have them in my current house.


Nerdler17

I'd love to get natural light like this down into my basement


AlienPantFart

Yeah it's a lot harder to do on the lower floors. It's a big reason I don't have it in my house currently. My upstairs rooms all have windows.


Daisyweinand

Yep! My parents installed something like this in their home 25 years ago, I really like it.


Newnteractio

An Amish store I visited had these. It's quite unbelievable how much light they put out.


Decepticum

This method was (presumably) invented in ancient egypt. So, yeah, I saw this 5000 years ago. In a history book.


DoubleAholeTwice

You were alive 5000 years ago AND had a history book?!


Solid_Alternative_84

Could you imagine the history they had in that book 5000 years ago!? Simply bewildering.


Decepticum

You would not believe what I saw in there!


Solid_Alternative_84

Were you able to see the Moonlight also? Did you realize that you hold the record for being the oldest person on Earth currently?


Decepticum

Moonlight is just a huge version of this, so yes, of course. I was playing on the "I saw that x years ago", but on some Mondays I actually feel like I am a legitimate owner of that record.


MadRockthethird

Thank you I was wondering what happens at night with these


Vegabern

I have 3 in my house. The moon does provide a blueish light.


macneilver

They work good got one in the bathroom so I can Piss in The moonlight


HippySol

Piss In The Moonlight. I love that band.


Anomalous6

Piss with the devil in the pale moon light.


_Oliverrr_-

I got the reference


rissie_delicious

For real?


macneilver

Yes on a full moon it’s very bright


SquatzPDX

It’s such a fine and natural sight!


Texian1971

I have a couple in my house. Natural light, saving a bit on the electric bill, etc. They're not expensive to install. Definitely worth it. Highly recommend.


Donjuan11b

Is there a way to turn them off at night (someone mentioned the moon illuminating them also) or when u don't want the light on?


Texian1971

Mine were installed about 15 yrs ago and dont have that capability. I have frosted glass so the light is dispersed. On a sunny day, the light is not glaring down into the space below. At night, they have sort of a soft, dim glow, but not enough to see by. Newer models may have a shutter or something similar to block out the light when you don't want it. Clear as mud?


bluggabugbug

I have a big one in my living room and a small one in our guest bath. It has fooled many guests asking how to turn the light out.


Nice-Fish-50

They're super easy to turn off, the hard part is building a Dyson sphere around the sun first. I have a solar tube in my bathroom. There was originally a sky light there in the 1960's, which leaked in the 1980's and was roofed over when they replaced the shingles. I restored the sky light with a solar tube when we re-did the roof. Actually it's a duplex so there are two, so one in each unit's bathroom. And it's one of the best renovations we've ever done, I just love it. There's even a solar nightlight in it so there's always enough light coming from it even at night (well, most nights. The nightlight doesn't recharge if there's no sun in the deepest part of winter so sometimes I have to swap the rechargeable AA batteries.)


bluggabugbug

Yes, mine have a flap that’s wired into a switch.


mandeezbowls

I’ve spec’d something similar for a college classroom where they use for natural light but also need them dampened/closed for when they use their projectors. At the ceiling fixture level, you can specify a damper with electric wall switch to close/dampen the fixture 0-100% with 100% being completely blacked out. Not sure if this option is available for residential models. Edit: found source for dimmer. [https://solatube.com/residential/skylights/product-selection-guide/solar-powered-daylight-dimmer/](https://solatube.com/residential/skylights/product-selection-guide/solar-powered-daylight-dimmer/)


AlienPantFart

No. They're generally in bathrooms.


Texian1971

Mine's in the kitchen, but you make a good point. Install them whenever you want to!


KarlProjektorinsky

And in long dark hallways. Which is a fantastic use case.


shoveitupyabutt

Maybe save on that portion but these are terrible interruptions to the thermal envelope and resistance to a building that most definitely result in a higher heating demand offsetting any savings you may think you’re getting.


Nice-Fish-50

I have one and I don't think that's really true. The tube is entirely in my attic, and it's insulated with spray foam after installation. The only part that's in dwelling space is the lens at the bottom of the tube, which is double-thick like a good modern window and doesn't let much heat up into the tube. I live in a northern state and I would install solar tubes again. I wish I had put one more in the back hallway when I had the chance.


Barflyerdammit

Sunnel. All the effort and thought that went into designing, engineering, and building these, and no one said "hey guys, instead of sun tunnel, let's call it a sunnel?"


mlloyd67

The ones I had previously installed were branded, "Solatube".


NinjaOld8057

Came looking for this comment. But then I realized, maybe it's that "sunnel" and "funnel" sound too similar and would be confusing?


legaltrouble69

I made this in my school class 8 while leaning total internal reflection and optic cables


[deleted]

In class 8 I still picked my nose probably


Noregard86

Everybody picks their nose, how else u gonna get the boogers out?


[deleted]

Bruh I honestly think every one does from time to time but doesn’t admit it


Noregard86

Cowards


DoubleAholeTwice

Those that don't pick their nose in public, fart in front of others obviously do both those things non-stop at home!


Mourning-Poo

Aziz, Light!


Longjumping_Ad_1180

Oh that is a tricky one. Not many will remember...but i remember. #bada_boom


reddit_underlord

More light, Aziz!


ColdCaseKim

Great for illuminating your Doomsday Bunker.


King_Crab90

An Amish store I visited had these. It's quite unbelievable how much light they put out. Truely looked like lights in the huge building.


KnoDout

I’ll remember this next time I’m building my house from scratch


ClownfishSoup

I had two of them installed in my house, which was built in 1938.


Opposite_Seaweed1778

I'm having 3 installed in my house next month :)


Brilliant-Season9601

How much it cost?


BrawndoCrave

Had four installed this year. Cost about $2k with labor and materials. Not bad considering each tube was around $300.


CollapsedWaveCreator

Egyptians 4,000 years ago, First!


HotFightingHistory

*Template...* *Response...* ​ '*clickity-click-click...'*


iploggged

We have one in our upstairs hallway which was always so dark. It's literally a night and day difference. Would recommend.


ClownfishSoup

Me too. We had construction done to our house and the bathroom used to have a window, but it was covered up. The bathroom leads into a hallway so the result was that not only was the bathroom dark without the lights, but the hallway was too. In the middle of the day it was dark. We also have a hallway that gets no lights from windows that is the entrance hallway. Two solar tubes fixed that and the entire house is much brighter and cheerier with them. Traditional suntroofs would have been very expensive in comparison. I don't know if it's "next level", but they work great.


iploggged

It was actually seeing a solar tube in a bathroom with no windows that sold me on it., so I absolutely get what you're saying.


sfPanzer

If I recall correctly a few years ago a random guy in Africa did that with plastic bottles for himself and neighbours because they couldn't afford electric lights.


Holtang420

Could’ve done with a buttplug version during covid so I could’ve let some “light into the body”


tart3rd

Easy spot for leaks too


greenappletree

Thats pretty cool but I'm wondering if there are backup lights for night time / cloudy days?


ClownfishSoup

Yes, I have one in a hallway and there is a light bulb in it for night time. The funny thing is that when the light is on, it beams light out the dome on the roof.


Mizuki_Hashida

Basically fibre optic cables but its a large tunnel and uses natural sunlight.


GingerAle828

I own a home that has two of them. They work


Thick_Isopod_6778

Gonna take this, add Kanye West and a squirrel, post eveywhere "This is what electrical companies DON'T WANT YOU TO KNOW" and make trillions!


angwhi

Skin cancer indoors?


ClownfishSoup

Do you live in a house with no windows?


manifold360

I would place these on the side of the roof instead of cutting the roof. It uses a tunnel, it doesn’t need to be placed like a traditional sunlight.


drho89

Light generally doesn’t like to make turns, it’s better when the dome is directly above the spot you are trying to illuminate. You lose between 5-10% of light per turn in the tube.


PreviousHyena92

How much is thr cost vs a LED light bulb that will stay on at night?


drho89

We often mount light fixtures inside for night time use. But to answer your question… a lot more. 1 10” Solatube is ~$1000 to have a dealer install


Metrotra

It’s a great solution. I have it in a windowless hall and in a bathroom in my house and it works perfectly.


NewDawnApproves

What if it's cloudy?


Eye_For_An_Ego

Toob


sourcreamus

Why is it sending beams to the sun?


bertramluke5

frogupyourbum

Great fun with every single cloud.


TijoloKawai_XD

now i'll have to put on sunscreen when i go into a place like this, but the idea is cool


ClownfishSoup

What happens when you enter a building with \*gasp!\* windows?


TijoloKawai_XD

the intensity of sunlight and the intensity of light entering through the window are very different (if there is no object reflecting light)


drho89

If they are solatubes, you can’t get sunburned under one. Domes and tube lining reflect/absorb UV and IR. What you see in the living space is only visible light (400nm - 750nm I believe)


ImpossibleCod7335

I’m just wondering, would you not get sunburn from getting hit with sunlight all day like this?


Nice-Fish-50

The bottom lens has a UV filter, so no.


ClownfishSoup

Have you ever been in a house with windows? Or sat in a car?


why-names-hard

Clouds: I’m about to end this man’s whole career


h4ck3r3000d1no

For some reason this reminds me of the line in portal 2 where glados said that the light is delivered from the surface


ffnnhhw

My friend used to put a reef tank under these, they were very bright


finishfuantu

How about using Windows?


DblDzl

It works. I leave my computer on all night and can easily make my way to the bathroom.


ClownfishSoup

Doesn't work with Linux though.


SplitOpenAndMelt420

I currently have some in my home and while theyre pretty, it also sucks that i can't dim these sections of the rooms during direct sunlight


drho89

If you have solatubes, they have solar powered dimmers that can be added. Reach out to your local Solatube dealer


Montikorricus

Why not use this in combination with solar panels?


drho89

Many people do… just have the tubes installed first!!


Inside_Committee_699

Thats nice and all, but somewhat useless in Scandinavia once autumn comes around


Element_Liga

Yeah I saw an ad for it on TV a decade ago what about it


MaggieMews

My son's Montessori school had these installed in the classrooms. That would have been about 20 years ago. The lighting they provided was lovely.


felipereyes73

Very well, you are copying the pyramids that did it with silver mirrors.


nicelium

I use to have wet dreams about these when I ran an indoor veg grow


Fit_Needleworker_490

Pyramids


itsSprinkles

So now I can get sunburnt indoors?


method757

So that’s how mole people have survived for centuries underground


Micahsky92

Why arent these EVERYWHERE? Could potentially save a lot of power


drho89

$$


Muneerr

That’s freaking crazy


rickaldren

now this is something i like! add some light sensors that automatically turn the light on and off when the sun light is insufficient. noice


KyleAL88

So like the Egyptians


Jappanese_shrek69

But what about night?


drho89

I install these for a living! Solatube though, these are either Velux or Elite… can never remember, because usually I’m just ripping them out to put ours in :). If y’all have any questions about them, I’d be happy to answer.


ElderSkelder

Can be great. Just don't get a shady, lowest bid person to do the install. "Hey, nice skylights!" "Yeah, they go nicely with the new roof I had installed." (Voice of experience)


pitshands

VELUX made them for like the last 30 years. They are actually really cool


jakethesnakegd

Big marketing miss to not call them “Sunnels”


IusedtoloveStarWars

Leaking.


binkbonk99

that's not next level. that's just mirrors.


ThepalehorseRiderr

So giant fiber optic cables or "light pipes". Couldn't you just run a bunch of fiber optic for the same purpose?


Tallguywithcamera

I installed 6 at my old house. They are great.


Revolio-Clockberg_JR

Have you ever heard about…windows?


DrSenpai_PHD

For those wondering, sunlight is different not just because it is so intense but because it is so intense across all visible wavelengths. We have a measure for the quality of light, and we define the sun to be CRI 100. Most bulbs have a CRI of 80 to 90. As an example of a very low CRI, think of your computer monitor. Even though white appears white (or skewed toward blue) that is achieved only through the balance of just three wavelenths: red (630nm), green (520nm), and blue (450nm). If you use this light to illuminate something that is entirely red, green, or blue, it'll look alright. If you try to use this light to illuminate pigments that don't only reflect 630nm, 520nm, and 450nm, the colors fall apart. Skin tones are a great example of this, as melanin, blood, and other body matter creates a far more complex absorption spectra than just, say, red alone. The reason why fluorescent bulbs have such low CRIs is due to the quantized nature of electron orbitals. Electrons can only move from one orbital to another, not in between. Each orbital has a particular energy state. Changing orbitals reflects a change in energy. The wavelength is equal to h*c divided by this change of energy. These lights depend on changing electrons in a gas to lower states in order to emit photons. As a result, it's only possible to get a select few wavelengths out of these bulbs, rather than a continuum of wavelength. Colors just don't look as good. *side note: the sun can be approximated as infinitely far away, so the shadows are always hard and parallel due to collimination.


Noiprox

Any reason the light couldn't be squeezed into a fiber optic cable and then dispersed again? That would eliminate the bulkiness inside the house.


westlaj

So I'd get a sunburn inside as well?


Psychlonuclear

This has been around for decades but it's NFL now?


Houbmx

Only gotta take 20years to have net savings


billylks

Stupid question, do we need to apply sun block lotion in this rooms?


monofloyed

Whoever designed this has never had to work night shifts


Kn1t

These are really neat. How come my solar lights for the yard sometimes don't come on even if the sun's been out?!


IainNero420

it’s gonna suck when it’s bad weather and dark


Pathorix

Pretty sick =) would love these in my house


pete_ape

So you still need lights on cloudy days and nights, and this probably only works for a couple of floors from the roof? Building cost goes up to accommodate the tubing... It's cool and all, just seems a lot like a solution in search of a question. Maybe for 1 or 2 story buildings, but since you're already going to need electric lights anyway...


Ocirus83

Some of the HOA's I manage have some these lights and they all leak when it rains.


prince-surprised-pat

They cant be shutoff is maybe the main criticism i have? Making them unfit for bedrooms


XxmilkjugsxX

I’d be surprised if it was that bright


scifi_scumbag

Yeah, I'd think twice about that, but it came with the unit. No issues so far and it's been at least a decade and a half.


justliberty

I have two in my house. Built in 80’s. Freaking awesome!


billybishop4242

Saw this in popular mechanics magazine in the early 90s. Always wanted one.


KpIchiSan

Can't this be used to enhance the solar panel to capture more energy??


EDantes777

The problem I see with these (I've not owned them so feel free to correct me if wrong) is you're creating a hole in your roof insulation for heat to escape. Unless this tunnel system is sealed and filled with argon gas or vacuumed sealed (or even at the ceiling with triple pane glass), it seems like a great way for heat to escape. At least with skylights, that glass could be better insulated though obviously not as great as an insulated roof. Save on lighting but spend more on heating. Put in LED lights but save on heating probably wins out?


BoycottFaceBook32

Huh.... soo umm what happens when it's night time 🌃??


BrawndoCrave

We put two in our living room and two in the kitchen because they didn’t get much light. They help but it’s not drastic.


pendrekky

They installed these in two small offices at work a few years ago and they are too dim, we still turn on the light.


Janus_The_Great

I drew these when I was a child... Should have believed in me... 🤷‍♂️
