[Michail] doesn’t mess around when it comes to lighting. He built this 100,000 Lumen chandelier to make sure his office is bright during the dreary months. The thought is that it will provide the health benefits of long sunny day. It has been hanging for about a year now, and he slowly came to the realization that it’s several times too bright for indoor use.
We know where he’s coming from though. When it’s dark at 5 pm we want it to be plenty bright inside. He started with an incandescent bulb, then moved through compact fluorescent and halogen bulbs before deciding to undertake the build. What you see above are 150W Metal Halide lamps. There is some danger to using these without an enclosure. They do emit some UV light and they can explode. So whenever you buy a fixture that uses them there’s a sheet of filtering safety glass sealing up the enclosed sockets. [Michail] decided not to bother with this safety feature, instead depending on the benefits of an electronic ballast. He says these reduce the chances of an explosion sending scorching hot glass shrapnel your way.
As we mentioned earlier, his conclusion is that just one of these bulbs is enough to illuminate his small office.



We’re not really interested in building a dummy load like this one for ourselves. But the concepts behind its design make for a nice little mental exercise as you read your way through the build description. [Pabr] wanted to build a dummy load which could be used to test a cheaply made gas generator. He wanted it to be as simple as possible, while providing a range of different loads. What he came up with is
