The problem with dimming AC LED Light Bulbs || DIY Trailing Edge Dimmer

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!

Not many YouTube creators are worth subscribing but you are exceptional. The topics (at least to me) peak my interest and are well plus throughly explained. I always learn something practical.

Keep inspiring.

This video's iteration of "and I will see you next time" was the most striking one so far.

I love that you are acheiving the same thing with a microcontroller and with discrete components. It's really interesting to see how to replicate a seemingly complex project with these discrete components.

You make all this black magic in our daily life understandable. Thanks so much!

There's absolutely no need to hit that notification bell my friend because I always know that you always upload videos on Sunday...
Every Sunday evening I open YouTube app and voila there is your video on top of my feed.
Now I've no connections with electronic/electronics but man I like watching your videos.
Love from India... Keep up your great work GreatScott

Hey Scott! Can you show us how works a Vacuum Fluorescent Displays? VFD, its a little bit old technology but looks still awesome ;)

[guatagel]

The ATTiny dimmer is an interesting project on itself. Thank you!

i always wait for his last moment expression " and i youuu next timmmme " ... your videos are such a help, though a bit advanced to understand.

This is why I still use incandescent bulbs. I have over a dozen dimmers in my home controlling upwards of 60 bulbs. Over 40 are in the basement alone on six different switches. I tried numerous brands of LEDs over the years and they all have different cutoff voltages. Some will dim great while others on the circuit go out entirely or are brighter than the others. Back in 2016, I bought over 1, 800 60 Watt bulbs which should last over 20 years.

You are great teacher in the world.
I always wait for your next video.

Thanks sir.

[BoGifford]

Thank you so much for this video, I have been waiting so long for a comprehensive video on this subject. Keep up the great work!

I built some dimming circuits following the ideas in here, it all works but getting it certified to install in an actual house is a different matter.
I ended up building a low voltage control module to work with a certified 0-10v dimmer such as Finder 15.11

Your voice is so calming. Great work, Great scot!

[JonathanDeWitt]

Another great video Scott. This was an enjoyable watch. Thank you for showing a commercial version and your version.

8:23 hahaha, when the shipping cost almost ten times than the product, very relatable.

[virtual_ninja]

I needed this video badly as I was trying this from your previous video ....and one thing I understood that I will stay from mains power

[coolfirefelix]

Thanks GreatScott, I was researching on FL5150 and u made it.

[virgogreg]

you go to so much effort in your videos, extremely professional and educational

Great Scott! Finally a useful ad! Downloading “my measures” right now! Hope it’s half as good and useful as this channel’s content... Thanks for these videos! Very interesting and easily understood tidbits of EE. With plenty of details.
