Do you have recommended dimmers that will cause LED lights to flicker at 40 hertz?

I am looking for something to plug LED lights into that will cause them to flicker at 40 hertz. Will any of your devices, such as adjustable LED dimmers, do that?

Unfortunately, we do not have any products that allow you to adjust the flicker frequency. You will likely want to consider a microcontroller solution such as an Arduino setup.
