When we read ‘light’ in scripture what do we associate it with? It is an unusual question - ‘what is light?’ because however we choose to answer this question we will always seat it in what we perceive and call light today - whether that be daylight - the light of the sun - the light from a bulb that we switch on so we can see, a torch light to show the way across a dark field on a camp site on the way to the toilet!
