580 watts..... :D. Why not work on cheap solutions to bring in natural light into darker parts of the house?
That's a lot of wattage.

Just curious about the frequency of the diodes and do they pulse simultaneously? Quite often I can perceive flicker in moving objects indoors.
We use constant current reduction dimming so there's zero flicker!
Isn’t that less efficient in power and can have different color?

#223I 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. https://www.harborfreight.com/10000-lumen-4-ft-linkable-diam... Also, if you've ever been in a Walmart or Forever 21 at night, you'll know that constant LED white light is probably not the best thing for your eyes.
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.

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

#224This is the second article about hardware supply from China I've read and it reads very much the same, albiet in a different niche (the other one was about SBC construction) -Anything you don't specify will be done least cost, and there is no amount of "least" which cannot be chased in manufacture. The other one noted if you don't specify the density of plastic for bags, or paper for bags and packing, you get clingfi…
Working with a Chinese vendors is an adversarial first relationship, where 差不多 is deeeeep in the culture (and, from my experience, tends to survive trips across the ocean). There are professional communication/training courses for working with Chinese vendors/colleagues that spell all of this out, because it's not some secret. It's just a very different culture, with high context communication (I'll let you read what…
Googled that ‘yes’ thing. Not different from my experience in other parts of the world. ‘Yes’ means ‘yes, sir’ only in the army. What is your environment?

#225i'm curious what are use cases for a lamp this bright?

That's the thing that drives me nuts about buying stuff manufactured in China.
They'll make this amazing Remote Control Car, with good suspension, a battery that lasts half an hour, plenty of power, and just all around amazing. But then it'll break after a day because somebody saved 1/20th of a penny by speccing this impossibly thin wire the thickness of a human hair to hook that powerful battery to the powerful motor and inside the remote.
They could have used actual wire-sized wire and had the most amazing product ever, for roughly zero more cost. (Possibly less, since surely it must cost _more_ to manufacture and solder micron-diameter wiring). It just makes no sense.

As someone living in the Nordics my experience already with central Europeans and especially so Americans is that these cultures are already much more high context than the Nordics. I guess up here we're all borderline autistic?

#228I would be quite scared to have such a monster lamp near me indoors. I mean, 60k lumens can cause temporary blindness, disorientation, and potentially retinal damage. It's near the welding arc territory at this point.

That's a pretty ungenerous take. Pushing timelines back doesn't solve the fundamental issue that you don't know what you're going to get when you submit that first large order. I've seen many situations where the samples and the manufacturing are completely different, even produced in different factories. They didn't do everything perfectly, but this looks like a normal learning curve for product manufacturing. Texti…
It's way more than just pushing timelines back. The person took $400k from people without knowing anything about how to provide what those people had already paid for.
I especially liked the "we tested the lamp we sold as 50k lumens to find out it only did 39k". Like, how do you even go setting up a product page for a product whose main selling point you didnt even test before?

That's how most Kickstarters operate. One of my first jobs was at a contract manufacturer that would get hired by ideas people without experiences to make the products reality. Kickstarter campaigns were our bread and butter. Usually they found us after trying it on their own first and failing.
