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.
