Miss posts like this on HN, thanks for the great write-up! I tried to launch a hardware thing like 10 years ago[1], but couldn't raise enough money. Fun experience nonetheless.

If you're not afraid of DIY and it looking (much) uglier than these lamps, you can buy extremely bright "cob lights" and make something yourself: https://meaningness.com/sad-light-lumens

This is super interesting, and I'd actually be quite interested in buying a 60K-Lumen lamp... but not at $1200.

Years ago, there was an HN article "You Need More Lumens"[1], which in turn led me down a rabbit hole.

I ended up purchasing:

   4 standard table lamps from Target,
  28 2000-lumen Cree LEDs bulbs[2] and,
   4 7-way splitters[3].
The end result is somewhere around 56,000 lumens. And I LOVE it. Makes me much happier in my home office, especially in the winter months.

In addition to the all the other stuff, including light spectrum differences, you can't just trust that a "37000 lumen" light (cheap from China ...) is such a thing. Some examples of "100,000 lumen" flashlights that ended providing more like 2000 to 3000 lumens: https://www.youtube.com/watch?v=6q_0wxzClkg

It's possible, they exist, many such LEDs are probably manufactured in China ... but the legit ones are probably more expensive, and you may need a more recognizable brand to do some QA, and keep pressure on the factory to not slip quality or inputs.

Consider the cheap screwdriver included with the lamp in this story: unexpectedly, many were more faulty than the cheapest $4 screwdriver you'd find in any hardware store. The more stories you read about manufacturing stuff in China, the more you'll see very strange things. It's not about nationality or anything, it's an extreme kind of optimization. If you didn't catch it already, maybe you didn't really need what you thought you asked for ... they're just checking/optimizing

Classic hindsight bias. In fact, you could be paying a lot of attention to politics and still think tariffs were not going to go so high. Here's [1] a betting market that regularly was below 5% chance of tariffs above 40% on Chinese imports in first 100 days of Trump's second term.

> Nobody saw this coming.

That simply isn't true. Here's a PDF from December 2024 (before Trump was elected) by the US Senate Joint Economic Committee:

https://www.jec.senate.gov/public/_cache/files/5c392e02-9eb0...

Throughout 2024, Donald Trump has proposed a series of tariffs on all goods coming from outside the U.S. or on goods from specific countries. His recent proposals include:

• An across-the-board 10 percent tariff on all products imported from other countries.

• An across-the-board 20 percent tariff on all products imported from other countries.

A 60 percent tariff—“or higher”—on all goods imported from China.

• An additional 10% above any additional tariffs on imports from China.

• A 25% tariff on products imported to the United States from Mexico and Canada.

Yes, everbody who was paying any attention at all saw this coming.

Look for the CRI rating of bulbs that you buy. It's a measurement of how close to a blackbody spectrum the bulb is putting out, the highest fidelity being 100. Note that this is not the temperature measurement, and you can have e.g. 2700K or 5000K bulbs with high CRI.

Newer LED phosphors are typically 90+ CRI, and I commonly find 93 CRI bulbs available off the shelf.

You can derate/"underclock" a regular LED and it will run significantly cooler, heat being one of the big drivers of LED lifespan. Downsides are less output per lamp (so need more lamps, probably why long-life lamps are expensive on a per-lumen basis) and you need to do a bit of DIY.

I don't know enough about lighting, but if I bought five of these, would I reach 50,000 lumens? Is it just additive? This would cost $250.

generally it's the opposite. people need a lot more light. an overcast window is like 50k+ lumens while a light bulb is like 500 lumens.

https://myopiainstitute.org/imi-whitepaper/imi-the-role-of-l...

lack of light is generally the leading hypothesis for why there is a myopia epidemic actually. from people being indoors most of the time for school or work.

though unfortunately scientists are still researching if it is a specific frequency of light etc... people are missing

Even high cri lights have a huge blue spike that doesn't match the sun. I don't know what chip OP uses, but you need a full spectrum light if you actually want very sun-like light. This page has some details:

No idea if there's any evidence or not of the blue spike actually mattering for human biology.

This reminded of the YouTube guy of "Smarter Every Day" who tried to manufacture a a grill brush completely in USA and still be competitive in the marketplace (i.e. China) [0].

It turned out that USA / "the west" lost the engineering knowledge to manufacture "stuff" (in this case injection molding and other procedures): Nowadays, we simply create the plans and schematics (e.g. CAD files) and let the Chinese do the building.

There are a number of pressureless casting techniques available. Investment casting is widely used, for instance. https://www.harmonycastings.com/ is a fancier example.

For this specific application, the manufacturing method determines the porosity of the material, and therefore the heat transfer.

CNC prototype parts will have better heat transfer than pressure die cast, and the pressure die cast will perform better than pressureless cast parts.

Congrats on launching your first 500 units!

I had a similar experience. I quit my job as a SWE at Google and built a hardware product on top of the Raspberry Pi.[0]

I don't really have anything helpful to add, but I relate a lot to all of the gotchas you encountered. Shipping a hardware product made me appreciate software so much more, especially SaaS products where you can ship a fix immediately.

With hardware, it's painfully easy to make a mistake and not realize it for 3-6 months. And by that point, you have this whole manufacturing pipeline you have to halt and unwind. And with overseas manufacturing, tariffs, and shipping costs, you can't even unwind some of this stuff, and you just end up with useless material that you paid 5-6 figures for.

We're definitely spoiled in the software world with the relative ease of fixing bugs.

Slightly more nuanced, I think we no longer have domestic industries making the components for the machines that make stuff. Many machine shops have Haas mills, but lots of Haas's suppliers are overseas. Regarding injection molding, we actually have better suppliers for the prototyping phases such as https://www.protolabs.com/ .

This reminds me of the Keyboard.io blog, where they documented their experience with the same kind of issues: https://shop.keyboard.io/blogs/news/day-743

Notably:

> When we got back, we watched as the laser engraving technician printed out a copy of our alignment template, deleted all of the guide lines from the file, imported the legends into the laser engraving software, and proceeded to try to eyeball the correct label placement.

> Going in, we were annoyed at how far off the legends were. In retrospect, it’s astonishing how good his manual placement was.

The problem with lights like that is the CRI[1].

Getting just lumens is cheap. Getting a full spectrum of light is where costs increase.

This is the reason I chose to go with the specific Cree bulbs (linked in original post) that get a 90+ CRI rating

Related thread I wrote a bit ago: https://www.reddit.com/r/Lighting/comments/1po7sxb/are_there...

I do think it's actually quite hard to beat the Brighter lamp on all of: Lumens, $, QoL (ie: Google Home integration + temp control), Form Factor (ie: not looking ugly), CRI.

I personally noticed issues w/ CRI & Form Factor quite a lot with my previous options.

CENELEC Guide 29, referenced in EU harmonized standards sets burn thresholds:

For brief contact (e.g., 1-3 seconds on adult-accessible parts), temperatures should stay below ~48-55°C depending on material; longer reflexive contact requires even lower limits (e.g., 43°C for extended exposure). A surface hot enough that hands can only tolerate it for "a couple of seconds" implies it's above this (likely 60°C+), risking second-degree burns.

I practice this means this product would not be allowed to be sold in EU. This would have been thoroughly tested to get the CE mark.
