I have some cheap LED lights, they say they're dimmable, and there's zero flicker when it's turned really low or really high. But for the middle 75% or so there's flicker. Total wattage is about 165~170. I don't know what it uses as a driver since that portion is encased in molded plastic, but it seems to feed a very solid 120VDC output. So does anyone know off hand of a 120VDC 200W PWM controller that could fit inside a standard home switch box (I would insert it between the LED driver and LEDs) or a relatively simple circuit design for one, with or without a microcontroller? I have some experience building circuits like this and programming with Arduino-compatible microcontrollers, but not enough to design this sort of circuit on my own (actually I probably could, but dealing with this high of voltage I'd rather use something pre-made or a guide someone might have). Thanks!

EDIT: If you aren't aware of a pre-built solution for this, does anyone know of a MOSFET that can handle 120V with a gate voltage of 5V or less to make building a circuit easier/simpler?

 

Are you using a leading or trailing edge dimmer? Supposedly the newer (trailing edge) are more compatible with LED lights.

 

Some LED fixtures are just not dimmable- period, at least not in a way that would be visually acceptable.

Here is an idea:

I've seen some of those. These are dimmable and dim effectively, they just *also* flicker during the middle 3/4 of the dimming range.

I don't know, this one just says that it's rated for 300W of LED lights and it's a newer Leviton model.

 

Divide and conquer.
You don’t know and we don’t know whether the issue is with the lamp or the dimmer.
Get yourself a different dimmable lamp, preferably different vendor or wattage, and test it with the dimmer.
Then you will know.

Good advice, I'll try that later this week. I'll also pick up a different dimmer switch to see if that helps. Thanks!
