I will be working on 100W LED lights to help with lighting my videos. I bought this kit on eBay for about $30US: https://goo.gl/HgWenj
I was planning to wire in a dimmer, like this guy did: https://youtu.be/c--5c3Egv4E?t=4m4s
But alas, the LED driver I got did not have a trim potentiometer like the one in the video. However, on closer inspection, I found that the circuit board has a spot for one, there just isn't one there:
So I wired one in there, and it worked perfectly!
Here's a link to a potentiometer you can use for this: https://goo.gl/kXgcRC
Stay tuned for a video where I put all of this together.
