We just put in lighting for an entire house. Here's what we learned: - Even high-end bulbs flicker badly when dimmed. Maybe flickering all the LEDs in the array with different phases would fix this. - It's illegal to sell bulbs that buzz in California. All our custom fixtures buzz. If you buy high end dimmers, they buzz less, but still buzz. More enforcement of consumer protection laws is needed. Manufacturers should…

FWIW, I just replaced a lot of bulbs in my house with Philips Hue white ambience bulbs because I'm very sensitive to flickering and we dim a lot. So far, no buzz or flicker. They are expensive, and so is everything in their ecosystem, but I finally have a light I like dimming.

Ahh. We're talking about different market segments.

The highest performing bulbs we have are also the cheapest. We went with hyperikon bulbs, IKEA pendant fixtures and mid to low end lutron dimmers in some rooms.

Those are totally fine. In hindsight, I'd probably have gone with 100% IKEA pendant fixtures that use standard bulbs and populate them with hyperikon bulbs. Sadly, hyperikon apparently went out of business. Thanks, Covid! Surely some other company makes decent dumb bulbs these days. No idea who, though.

The problems start once you buy modern fixtures, where the LEDs and power converters are integrated into the fixture itself.

Earlier quoted context omitted.

I 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

Jesus 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!

I 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.

My wife laughs a little at my lighting mania[0].

I bought a bunch of desk lamps and put them around the perimeter of my home office, and equipped each one with a 300W equivalent flood bulb pointed straight up (I like indirect light best). Tied them all with HA so they turn on with the main room light. So when I go into my office and turn on the lights, it's like turning on the sun. Not literally, of course, the sun is pretty bright, but it's a heck of a lot brighter than any other area of the house.

Pretty sure it's the only reason I survive winter in a good mood.

[0] When I go down to the home store, she almost always asks what bulbs I'm looking for this time. LOL

I bought a studio LED panel from Amazon (for videography generally). It came with a stand that attaches to the desk to be used as a webcam light but I mounted it on a shelf and it hangs over my head like the sun. It has a 3000k-8000k temperature range and that and the brightness can be controlled by a remote. There are a bunch like this available under different brand names. For the price I've found it to be a good solution for now and I also have a photography light as a bonus.

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…

One 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-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.

i still use 2 x 250W (5000lm) halogen sticks in a 6x3m room, for ~15 years. it's not enough and not flat, i know. (still much better than any stupid chandeler, like 2000lm).

i have tried and tried several CRI90 and CRI95 LED lights, bulbs and strips, but the spectre is not same. Like Fruits look different. Ah, May try some panels too. Of course, none of the price-of-secondhad-car ones.

No mention of tint, only color temperature. > In my experimentation I discovered that I liked closer to 5000 in the mornings and closer to 2700 in evenings. The color temperature of the sun at noon is 5000K. So at noon, you want your light to be 5000K or higher, especially outdoors (who needs auxiliary light outdoors at noon? Exactly. High color temperatures are bullshit.) But it really has more to do with eyes than…

The only reason why most old CRT displays were calibrated for a 6500 K color temperature was because the red phosphor had a lower efficiency than the others.

Using a white with less red and more green and blue allowed the vendors to advertise a higher brightness for the displays.

The same reason applied to fluorescent lamps. Choosing 6500 K allowed the vendors to advertise a higher luminous flux at a given electrical power.

Nowadays there is absolutely no technical reason to use a white with the 6500 K color temperature, even if the low-quality LED lamps with a single orange phosphor still have better efficiency when emitting more bluish light, but those have a too low CRI to be an acceptable lighting solution.

Nevertheless, for the lighting of my home I do not like a too yellowish white, so I use LEDs with the 4000 K color temperature, which, unfortunately, are much harder to find than those with a yellowish 2700 K or a bluish 6500 K.

Very related to this, I've been trying to relocate a video about "making a sun in a box" where the creator does the following: - goes over power and lumens, basic wiring for a bare LED. - details how the color of light matters. - instructs how to measure the focal length of a fresnel lens for parallel light rays. - how to make an appropriately sized box that can be stacked in both directions to crate a "window" effect.

I've spent tens of hours trying to relocate this particular video; I thought it was a "DIY Perks" video but either he deleted it or it was someone very similar. It's so similar to DIY Perks' projector project and satellite dish sun project that it's uncanny, but it's neither of those videos.

If anyone knows this video and has a link I would be appreciative.

This isn't quite what you're looking for, but this has some of what you're looking for, which is how to get the "parallel light effect" that the sun has, so it doesn't look like a bulb, and diffuses properly:

Hope this helps a little.
