it is indeed a head scratcher.!
Light of any kind is made of photons and waves, our sun of course is just a huge nuclear reactor ..as hydrogen gets compressed near the core, nuclear fusion occurs, heat and photons are made..the light we see are the visible particles of the photons. As for , artificial light...I guess it would depend how one acquires the energy to create it...if from a hydro-electric dam to power your house or from organic photovoltaic solar panels...could one say its organic?. The closest light to being organic for efficiency IMO..is the LED... when ample current is applied to the semiconductors, electrons are able to recombine with electron gaps within the device, releasing energy in the form of photons.
