Fix the issue with read posts. Can't stand having to see the same top posts over and over again.

Looking at the datasheet and pictures I think the heatsink is just aluminum. Looks like an extrusion (which means it's the same shape over the full length) with a solid center that they machine down in the middle area to mount the LEDs. The large amount of material and good conduction of the aluminum will absorb and distribute the heat without needing water cooling or heat pipes.

These LEDs use up to 200W and the heatsink on here probably weighs more than 10x as much as a heatsink on a 500+W graphics card. Watercooling and heat pipes are necessary when you need to get a lot of heat out with a minimum amount of material, such as for cars and home computers. Costs more than a big block of aluminum but the you don't need to move that much wieght around. For a light like this, the extra weight and space it takes up doesn't matter.

This is from 2022, it is not news. Are there any more recent articles on this? How'd it go?

Clickbait.

Article is nearly 10 years old.

Article contains no studies or surveys showing this result.

The 50% figure is calculated by assuming a paltry annual raise and consistent large pay bumps by switching companies.

Cheap drivers that drive the cheap LED modules too hot without enough cooling.

The lightbulbs thing was (possibly) different. There's some physical limits on the performance of lightbulbs so the time to failure test was more of a proxy to make sure bulbs of a certain wattage were outputting similar strength and color light.

I don't know if there were other reasons this glass tech didn't catch on besides the obvious capitalism issues, but the lightbulb thing is definitely a misunderstood piece of trivia.

They don't do shit about the sound and smell of the two stroke motors. That's the sound that pierces noise canceling headphones.

You can set the taskbar stuff to stay on the left, at least in the version of win11 I use for work.

I hate that I can't tell if video game, render, or AI generated anymore.

Yes, but the difference in safety over 12 years from a 2000 -> 2012 is much bigger than 2012 -> 2024. There are a lot more features now to stop a crash from occurring, but in terms of crash safety which is what a lot of people consider in buying a car, the difference is much less.
