Cities are swapping traditional light bulbs for more energy-efficient brighter LEDs. The rise of these blue LEDs are creating problems for our night sky and our health.
So LEDs can either be strobed or powered consistently with no blinking at all. It’s a design choice and it depends on how you convert the power from AC to DC and how you want to control the brightness of the LED. It’s cheaper to feed an LED power that is modulated/strobes so all the cheap vendors do that. You can also get away with strobing the LED to achieve a brightness assuming you do it at a very high frequency so our eyes don’t perceive it. If you buy a quality LED light fixture there should be no strobing effect what so ever.
