Flash/torch

This is the flash/torch on the back of my mobile phone. A pretty small thing producing quite some light.
Of course not the same as my torch or my flash for the big camera. But compared to what we had to deal with in the old days.
I remember my father started with one bulb per flash, and later came cubes with 4 flashlights. Now these millimetres of light do almost the same, and that over and over again.
