Oh, sure, if you make stuff hot it will give off light. (And other 
frequencies, for that matter.) But you don't need to use electricity to 
make things hot; you can use *anything* to make it hot, and it will 
glow. So it's not really an electrical effect.

More to the point, presumably if you shine a light on some kind of 
conductor, it will induce a current... (And yet nobody has found a way 
to use this to convert sunlight to electricity yet. They all rely on 
obscure chemical and physical properties to try to do the job.)
