Cameras nowadays are produced with high technology CMOS sensor, which produce very high quality images in low light situation.
And the LED technology has been rapidly improved for the past few years, giving you a lot brighter light, more lightweight, and even smaller size.
This is leading many of the photographers to switch from flash to LED lighting for their photography.
Also don't forget that most of the mobile phones (of course and the mirrorless & DSLR cameras) are capable for shooting 4K videos, it's no doubt that the LED products will be slowly replacing with the flash lights.
