I have a friend with a condition a bit like epilepsy and LEDs set him off all the time.
Attacks have even been brought on by passing cyclists with red LED lights.
Weirdly my older Phillips hue does not, so either that is not flickering or it is doing it much faster.
- faceplanted 7y agoLED lightbulbs are different from the bare LED's on a bike light, they use blue LED's under a layer of phosphor that absorbs it and re-emits a variety of shorter wavelengths simulating white light and different colour temperatures.
