That would probably help some. Really, they should just flicker faster. There’s no reason not to do PWM at a kHz or 10, and nobody is going to see that flickeri

It's tough to make a completely silent inverter that works near the peak of human hearing sensitivity. It can be done, but it's likely to be more expensive. Going all the way to 20 kHz+ is probably the best strategy. LEDs can be driven well into the MHz range, but if you go too high, RF emissions compliance starts to become a problem.
- monochromatic 9y agoThat’s a good point. Call it 50 kHz to deal with people who have abnormal hearing response.
