DIY Perks [1] has a good tutorial on how to make a super bright LED panel from LED strips. Quite easily, actually.
Been using one of those in my office for the last eight years or so. I use a server PSU for power.
I was surprised to see how bright it is when I once went outside while it was on. Not only was my window the brightest in the entire street by far. But it actually illuminated the trees around my window.
If I was to build it again - and especially for a place like living room - , I would build it so as to also simulate sunset. That is to say, that it will automatically lower the brightness and shift to a warmer spectrum in the evening. Otherwise, this thing messes with your biorhythm and gets you out of sync with normal daylight hours very quickly.

- manmal 5y agoSince you seem to be a heavy user, and if you don’t mind me asking: Has your eye sight deteriorated in those eight years, and how is your sleep quality?
- leobg 5y agoNo problems with eyesight. No glasses or anything. I see the light as basically replacing the brightness I would be getting if I wasn’t sitting inside my office instead of outdoors. And sleep: I don’t have any trouble sleeping, no. But as I mentioned, using a such a bright light in the evening will fuck with your day/night rhythm. If I’m not diligent to turn off those lights at sunset, I’ll easily be working up until two or three in the morning. If that happens, the problem isn’t that I wouldn’t be able to sleep (I will) or that I would sleep badly (I won’t). It’s just that it shifts my rhythm out of sync with everybody else.
- manmal 5y agoThank you!
- underwater 5y agoHe also created a version that simulates sunlight: https://www.youtube.com/watch?v=6bqBsHSwPgw https://www.youtube.com/watch?v=6bqBsHSwPgw
- BizarroLand 5y agoYou should also take into account the costs associated with running and powering the COB led he used for that sun light. https://www.youtube.com/watch?v=bBV-1VNWscA https://www.youtube.com/watch?v=bBV-1VNWscA
- joshspankit 5y agoCame here to mention both DIY Perks videos, as well as to say that the ability to change colour temp is practically vital.
- unfocussed_mike 5y agoYep -- I love this video. The detail he went into on this is remarkable; it taught me a few things about the limits of pretend sunlight as a photographer, and why some pretences work and others don't.
- namibj 5y agoYuji does indeed make the good stuff, just really in a consumer-friendly form factor unless you count the low-power bulbs. For your sunset approximation, you could add some warmer ones and fade over; they also have some dual-color strips with two different color temperatures evenly spread to allow for seamless mixing.
- leobg 5y agoExactly. You’d probably need fewer of the warm colored strips, because at the time of day when you will want to use them you’ll also want less light anyway.
- namibj 5y agoWhile true, the ability to work in a warm white atmosphere is a benefit not to be ignored. (I'm using a 20W/m 5m strip of BC-series 1900K for my living room, along with a 10W 4000K bulb hanging from the ceiling.)
- necovek 5y agoSince the OP is quite courageous about claiming someone "inventing" this in 2017, I'd like to highlight your prior art: > Been using one of those in my office for the last eight years or so. I use a server PSU for power. And as you mention, articles on it have been circulating for even longer.
- Udo 5y agoIt's Yudkowsky from LessWrong, he is actually a quite insightful thinker, but his disciples claim stuff like this all the time. LessWrong is an extreme echo chamber. For me the breaking point was Roko's Basilisk, a self-proclaimed "most-dangerous idea of our time".
- thewakalix 5y agoAre you honestly claiming that the author believes that Yudkowsky was literally the first person in history to suggest making lights brighter? Also, you should read anything Yudkowsky himself has written about Roko’s basilisk. He’s never claimed that it could work, or that it’s dangerous at all. (“Why did he ban it then?” Because he wanted to prevent it from inspiring an infohazard brainstorming session that could produce a real danger, and he apparently hadn’t heard about the Streisand effect.)
- Jiro 5y agoYudkowsky claimed that the exact basilisk as described by Roko wouldn't work, but he also believes that something like it would.
- thewakalix 5y agoSort of. He believes that if people try to come up with infohazards and then immediately spread them, there’s a nonzero chance that they succeed. It’s unlikely, but still not something to encourage. (This is not the same thing as “being certain that a minor modification of Roko’s basilisk would produce an evil time-travelling AI,” to be clear.)
- 14 5y agoI was going to suggest diy perks but thought you were going to link his artificial sun video [1]. I’ve been wanting to build one but not sure where I could fit since it requires a bit more space then a bright led build would. https://m.youtube.com/watch?v=6bqBsHSwPgw https://m.youtube.com/watch?v=6bqBsHSwPgw
- leobg 5y agoJesus Christ. I hadn't actually seen this one. Wow! You could say he's going overboard in this one, with that fish tank sky simulator thing. But then: How much do we spend on airfare and lodging just to wake up to this kind of light? What an amazing improvement in quality of life this can be. Thanks for sharing this one!
- 14 5y agoI really think it could boost a persons mood on a dark day his looks so incredible I would love to try it and even just brighten up one room. But I think if a guy were to make these as fake skylights you would really have a business.
- sitkack 5y agoOne doesn't need to make lights out of led strips, shop lights have transitioned to LED. $20 each, https://www.harborfreight.com/5000-lumen-4-ft-led-hanging-shop-light-64410.html https://www.harborfreight.com/5000-lumen-4-ft-led-hanging-sh... 5k lumens, 60w I also came to post the DIY perks video about simulated sunlight, the effect of parallel rays really changes the geometric mood of the room.
- lazide 5y agoIt really does help. Just don't keep working into the night under them, because whoa boy - talk about sleep disruption. Those nice bright lights make it surprisingly easy to work until 6am and not even realize it.
- sitkack 5y agoI have mine hooked up to a remote so I can turn them all off at once. Either propped in the corners of the room or bounced off the ceiling. They are much too bright to have them shining directly.
