In this video I take a look at one seriously interesting LED.Check it out here: bit.ly/500w-yuji-LED
Imagine trying to sleep and your neighbor turns on the sun
I think it's incredible how broad the spectrum of people's hobbies is. An LED is just that to me, an LED. But to someone else it is a whole lot more. You just gotta love that.
I reckon this would be very useful for slo-mo shots too, as the faster the shutter, the less light goes to the sensor meaning you need a lot of light.
British man got tired of the shitty weather in england, creates his own sun
I had no idea a $500 led even existed. Thanks for sharing!
Husband: "Is that a UFO? What IS that?"
Hey, I work at Sony Pictures and I walked past a set today that had such an effective artificial sun that I thought they had opened the roof somehow before I looked up at an array of thousands of white LEDs. Grid pattern, about 3 square inches between, and 30 feet above the ground. Not sure if there were any kind of optics (shades, reflectors, lenses, etc) but they looked bare, definitely no diffusion. Maybe you should cover your ceiling in LEDs!!!
You could probably build an amazing projector out of this, using the LED as the backlight
As a space engineering student myself, I really enjoy your videos. It would be really interesting, to mill a passive heat sink with some heat pipes. How big would it need to be?
Amazing, I used to work for a stage lighting company back in the day and we'd use lamps as big as a small fridge that required their own diesel power generator to achieve this amount of light.
Deberías darle subtitulos en español a tus demás videos, son muy buenos y estoy seguro que muchos más habla hispanos nos gustaría eso 🤩
Imagine that heatsink in a computer! If that doesn't get your CPU down to room temp I don't know what reasonable air-cooler will! Also, the shadow thing at the end was actually lovely. A feature length movie needs to be made purely with shadows like that!
I guess this is the LED Fractal Design will use as the power indicator in their next computer case...
Supercool! Thanks for sharing the first experience with the LED with CRI 96 (and the obvious power). I'm interested in LED's (made some long lasting fixtures and impact-proof mobile lights). I don't like the commonly available cheap bulb-shaped SMD LED lamps as they are badly constructed (projected to last at most ca.500h when the LED's specs say 25k - 50k h) and their CRI is a joke. I'm glad someone presented the actual good LED with proper CRI. Way to go, Yuji LED!
I'm a theatrical lighting designer and this is very fascinating technology to look at for me. Could be ideal for stage lighting.
A bit surprised to see so many reactions wondering about the purpose of this (or even disregarding it as pointless). This is a gods end for anybody shooting video or film. Yes, you don't need 500 watts for lighting yourself at a desk, but for serious filmmaking of larger locations, this is brilliant. I'm reaaaaally looking forward to what you come up with, as I'm currently looking for affordable "fake sun" solutions for a short film I'm gonna shoot next summer (in fact, I'd love to have 4 of those!). Depending what else is needed to run this effectively, this light will come up at a fraction of what professional lighting would cost, while at the same time it offers some of the best CRI values on the market. It's almost too good to be true. Right now I see the fan as the potentially biggest problem of it. While I don't think you can get it completely quiet, any way of getting it quieter than what it is right now, will be a huge improvement. Or maybe I should just give up on the idea of on-location audio ;-)
Just one problem if you're going to mimic a sun with it; This outputs 5600K light, although direct sunlight is warmer than that. What you need is the 3200K version of this for direct sunlight, then a 5600K version that fires up into the roof and diffuses down as skylight.
Very curious to see how you approach collimating the light from this... I've been trying to build a reflective system for collimating the smaller 100w chips but the heat situation is hard to work around.
