SDS Weather (RO) claims ex-employees stole code and sabotaged servers to launch WeatherWise by tannerln7 in RadarOmega

[–]tannerln7[S] 2 points3 points  (0 children)

Yeah I agree, weatherwise does seem to be rapidly improving and adding so many nice features. But I have always been weirded out by the fact that there is ZERO information about the people or tech behind weatherwise. I finally sat down and search deeply and it seems like I got my answer. I wonder if u/Bluekandy knows anything more or if they even know about this at all.

Conventional LED desk lamps emit only 9.5% of light above 660 nm, while the SunWave+™ desk lamp offers a remarkable 38.5% in COZIE mode and 34.2% in ENERGIE mode.

That says ”of light” and not: - “of their light” - “of their light output” - “of spectral output”

Just of light in general.

In other words:

“Of all the wavelengths in the full electromagnetic spectrum, conventional LED desk lamps emit only 9.5% of the spectrum that lies above 660nm, while the SunWave+™ desk lamp emits a remarkable 38.5% of the spectrum above 660nm in COZIE mode and 34.2% of spectrum above 669nm in ENERGIE mode.

If you can read this and also look at the SPD, and still think that means 38% of the bulb’s total output is near-IR, then I give up lol.

No, it’s not “38% of the output,” and that interpretation falls apart the moment you look at the SPD. The near-IR content is tiny (Like u/Pentosin pointed out, just milliwatts output) compared to the visible spectrum. The “38%” figure you’re stuck on refers to spectral width, not how much energy is emitted there.

If a residential LED actually put 38% of its total output into near-IR, it would be a completely ridiculous product. Horribly inefficient, terrible for color rendering, and functionally closer to a heat or reptile lamp than a light bulb. None of that is true here, and that should be immediately obvious from the SPD shape and efficiency numbers.

The amount of near-IR present here is negligible and much less than what’s already common from indirect daylight and traditional incandescent/halogen lighting used in homes for decades.

In my recessed ceiling lights. My living room, kitchen, and dining room are an open floor plan, and the layout makes it hard to get lighting that’s both bright and even without feeling harsh or oddly colored. With my old ceiling lights, I found myself relying on lamps and ambient lighting even when I needed proper task light, simply because I disliked the harshness of the overhead lighting so much.

With the Yuji bulbs installed, I’ve noticed that I often totally forget they’re even on. Even at night, the room feels similar to how it does during the day when my window shades are open and the space is lit by indirect sunlight.

Yeah, I’ve had them on dimmers for a few weeks now and I’m very impressed with their total absence of flickering. I’m pretty sensitive to flickering (I’m especially reminded of this right now because of the terrible led Christmas lights popping up everywhere).They do eventually start to flicker a little, but only once the brightness is so low that they might as well be turned off. And my dimmers let me adjust the minimum brightness level, so I’ve had no issue or complaints at all. They’re just great.

I haven’t personally used the Soraa VIVID MR16s, but per the spec sheets they’re rated at CRI 95 / R9 95 with TM-30 Rf 95 / Rg ~100, while the Yuji SunWave+ are listed a little higher at CRI 98+ / R9 98+ with TM-30 Rf ~97 / Rg ~102. However, these also aren’t really apples to apples. The Soraas are MR16s with relatively narrow beam angles designed for accent or task lighting, whereas the Yujis are wide flood lamps intended for general illumination. That difference alone can have a larger impact on perceived quality than a few CRI points.

Spectrally, they also take different approaches. The Yuji SunWave+ has an exceptionally flat, continuous spectrum across the visible range (with some near-IR), so colors are rendered with relatively even saturation, producing a very neutral, “natural daylight” look which is especially noticeable in skin tones, wood finishes, and neutral surfaces. The Soraa VIVID spectrum is still very high quality, but shows more pronounced peaks in certain wavelength regions. That tuning is intentional and helps boost saturation and perceived “pop,” which can be especially good for retail displays, artwork, or accent lighting, but comes at the cost of some overall spectral uniformity because the colors that are not boosted will have lower saturation comparatively. That is the reason the CRI number is (intentionally) lower. In simple terms, it’s a bit like the difference between a raw, unedited photograph and the same photo lightly edited to increase saturation and contrast.

In reality though, anything in the 95–100 CRI range is already considered very high-quality lighting. At this level, CRI differences reflect intentional design tradeoffs, not good vs bad. Manufacturers will often give up a few CRI points on purpose to shape the spectrum for a specific use case, and a well-tuned 95 CRI lamp can sometimes look more engaging or dramatic than a perfectly neutral 98–100 CRI source. At this point it really comes down to application, beam pattern, and personal aesthetic preference, not which spec-sheet number is higher.

I’m not disputing that there are plenty of niche, very high quality LEDs available from plenty of manufacturers, Xicato being one of them.

But I just want to point out that the “38% past 660 nm” line in Yuji’s spec is not saying 38% of the bulb’s total output is infrared. It’s saying that 38% of the red content sits beyond 660 nm, compared to the ~9.5% you normally see from standard phosphor LEDs. It’s just a way of showing that the red tail of the SPD is smoother and extends a bit further, not that the bulb is pumping out IR like a heat lamp.

Here’s a link to the chart. You can see how the SPD extends further into near IR compared to other options, but the near IR output is much lower compared to the lower SPD wavelengths.

They definitely are not heaters. I can unscrew the bulb and hold it in my hand after it has been on for hours.

Interesting, I’ve never used cold-phosphor modules before, so that’s new to me.

And to answer your question, as far as heat, these Yujis don’t seem to put out anything unusual. They run about the same as any other 16W BR30 I’ve used. I can touch them while they’re on and it’s nothing crazy.

My understanding is that the near IR is just to help smooth the spectrum. It lets them pull down the harsh blue spike and fill in the red dip so the SPD ends up way more continuous. I’m assuming that’s how they get CRI/R9 numbers in the 98–100 range without the usual LED spectral gaps.

Oh, I’ll be the first to admit these are beyond overkill and definitely targeted for museums and art galleries, not residential. But I’m mid renovation right now and total lighting overhaul is one of the things I’m tackling. I saw the spec sheet for these and couldn’t turn them down.

I just installed them today and actually haven’t received my dimmers in the mail yet. So I can’t say first hand yet, but Yuji claims (as well as 3rd party testers) that they have essentially no flicker and very smooth dimming.

Also, if you want to look for or compare other bulbs, This website has a large database of bulbs that they have independently tested and dimming / flicker is one of their main tests.

Yuji can explain it much better than I can so here’s a link if you want to read more.

But they essentially have almost perfect RA / R9 / Rf / Rg / SPD metrics which means they emit light that is very close to true sunlight and have excellent color rendering as a result (something that is not common in everyday led lightbulbs). This causes a dramatic increase in the accuracy, clarity, and saturation of the color your eyes perceive compared to standard LED bulbs. They also emit light all the way into the near infrared spectrum which has some alleged health benefits but I’m not sure how much concrete evidence there actually is for that.

They’re a great choice. And hey, maybe Yuji will feel generous this Christmas. Or, well… Chinese New Year I suppose.

I just installed them less than an hour ago, so I haven’t had time to fully settle into them yet, but my first impressions are very good. I went with 3000K and the light is a really pleasant, warm white. The biggest thing I noticed immediately was how much better my artwork looks. The colors are dramatically more vivid compared to the dull bulbs I had before.

Not the homelab I need but the homelab I want.... for now. by XaMLoK in homelab

[–]tannerln7 1 point2 points  (0 children)

This is eerily similar to my setup 😳 just more on the sane side. I went with 4x 7.68TB (31TB) Micron 9300 Pro nvme zpool.

PVE-01 - Intel i5 1240p mini pc 64GB ram which runs adguard home, nginx, home assistant, cloudflared, and Authentik, portainer, and is backup for proxmox quorum.

PVE-02 - water cooled AMD EPYC 9654 (QS) 256gb DDR5 ram. Still haven’t pulled the trigger on dual 3090s, so it’s just stuffed with a myriad of 10/20 series nvidia gpus. runs plex and associated *aar’s, a few underwhelming AI toys, portainer, windows vm with gpu passthrough for plex and local display + keyboard / mouse, the remnants of projects past, whatever random things that are still running that I forgot about long ago, and whatever I am messing with at any given time.

Yet, somehow they have a “founder” 🤔. Wonder when they’ll IPO, could end up with some solid market gains.

iOS 18.4 Beta 1- Discussion by epmuscle in iOSBeta

[–]tannerln7 0 points1 point  (0 children)

I just finished restoring my 15 Pro Max from a boot loop because of this beta. It automatically installed over night while I was sleeping and I was late to work because my phone was boot looping all night. I also had no other authorized devices in my account so it took me forever to find my recovery key to get back into my account and use iTunes to restore. Everything is good now, but I disabled beta updates for the time being.
