  • 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.













  • Right? They portray it as a problem rather than as a sign that cars have finally hit the point where they’re not dramatically improving in reliability, safety, and efficiency nearly as quickly anymore. That is not a bad thing really.

    For capitalists, a healthy used market is a bad thing. Captial requires continuous production to make returns on itself.

    One of the few things anymore that has a really strong used market besides cars is housing, so the capitalists switched their investment from developing new housing to vacuuming up the existing stock to instead collect rent and increase the value of their portfolio.


  • Gas being a better energy source than batteries in every way except for the health and environmental issues is a real bitch and why this is such a problem. Cords are a hassle and you will need a lot recharging batteries all the time, so you notice the downsides immediately and acutely. These are solvable problems though. Even running an efficient gas generator would be better for the health of landscaping contractors than being around 2 strokes all day.
