Fix It!: Self-Dimming LED Downlight || How a new hardware revision improves everything!

How JLCPCB Keep $2 PCB Prototype & Build PCB best: JLCPCB Story & Full-scale Factories: Previous video: Everything about LEDs and current limiting resistors video: Facebook: Twitter: Support me for more videos: In this episode of Fix It! I will be having a look at a self-dimming LED downlight that quit working after only 1.5 years of usage. I will not only find the simple mistake that makes the light useable again but I will also explore the lights circuit secrets. I will show you exactly how it works and I will also directly compare it to the same lamp type which was produced a couple of years later and show you how the new light does everything better. Let’s get started! Thanks to JLCPCB for sponsoring this video. Visit to get professional PCBs for
