I have a microscope lit by a 12V 10W car light bulb, which doesn't work well because the lamp generates too much heat. So I replaced it with a four-LED array with the same spec and fitting (meant to be used in cars). This provides good lighting without heating up, but the 50Hz flicker is very annoying.
I assume a capacitor would be the solution, but it is 30 years since I soldered amplifiers and calculated circuits, and I don't know much about LEDs, so I would greatly appreciate some advice on how best to solve it. I haven't actually measured, but I assume the input voltage is about 12V AC.
