recently i make a ultra fast response ldr circuit,and im curious about how fast it can respond to a light ,so i put it to dark activated mode and connect it to a led strip,put it in a dark room and connect the output to a led strip and put it right in front of the ldr so when the ldr didnt receive any light it will activate the relay and turn on the led and deactivate the relay and it will create a pulse that turn the led on and off rapidly and from that i know that this thing have an extremely short delay between relay on and off,then i came up with an idea making a stroboscopic effect light with that,i connect other led in parralel with the main led strip and it work
