In this video we are going to build this powerful LED light using a high quality COB LED and a power supply unit from an old computer. This is a highly versatile LED light due to the brightness adjustment knob and the option to mount a softbox for more pleasant lighting. Since the COB LED that is used for the light has a really high CRI rating of over 97 and a color temperature of daylight, it almost matches the sunlight and produces true colors unlike my previously used cheap LED bulbs. So the first thing we will need is a power supply unit. I got mine from an old computer that wasn’t functioning properly. Since we’ll only need the outer case, it is best to use a non-working one. I also recommend you use a PSU that has ventilation holes on the sides and a hole for the fan to allow for as much air movement as possible. To power the LED I am using this DC 24V power supply that can deliver up to 6 amps. Since the LED that I will be using works from 34 volts, we will need this voltage booster module to supply the required voltage to it. The two blue variable resistors on the board adjust the current and voltage on the output leads. Since the LED produces quite a lot of heat at full power, I will be using this aluminium cooler with a fan to keep the LED at a lower temperature. I chose this AMD cooler used for computer CPUs since it is relatively small and quiet and will fit inside the case perfectly. The LED that I chose for this project was supplied by a store on Aliexpress which specializes in high quality cob LEDs and LED strips. They provide great prices and global shipping. So the LED that I am using is this ultra bright 100W daylight white COB LED that has a color rendering index of over 97, meaning the colors that are produced by this light are very accurate and almost identical to sunlight. The light comes with a plastic mount and as you can see the LED is relatively small but incredibly powerful for its size. As you can see, the light is incredibly bright and gives off a color temperature similar to daylight. And once the LED warms up, we can see the fan spinning at maximum speed but still barely making any noise. Since we are using this high quality LED, the objects look as if they were lit by daylight, making this a great studio light for filming or photography because of the great color rendition. It also does not flicker on camera unlike my previously used cheap LED bulb light, as seen in the comparison. Overall I am really happy the way these lights turned out and I hope you give this build a try! Feel free to leave any comments below and I’ll see you on the next video! Thanks for watching!
