In this video we will have a closer look at the electrical challenges AC LED light bulbs offer when it comes to dimming them. That means I will tell you a bit about how they are built and we will also determine the differences between leading edge and trailing edge dimmers. At the end I will then show you how to create a DIY trailing edge dimmer that you can even build at home for cheap. Let's get started!
