I applaud your fascination with light, it was one I had too for a while, I have some history in lighting too, my thing was arc discharge when that came out for portable applications, before it got overtaken by LEDs. I had a company working with Osram in development of them :). I'd actually never heard of the Phoebus conspiracy but it does make some sense. I love the progress LEDs have given us, but I have some concerns now that it might turn out to be a double edged sword, the brightness from them is getting a little too much - the light output now, and the nature of of it, high UV content close to collimation like lasers is something I think will become damaging, if it hasn't already. No-one seems concerned that the light output power of these things is starting to dwarf what our eyes are normally exposed to in the natural environment. I saw an article just recently showing a US football stadium sporting its new light display, the whole thing was blue LED lights, the stadium completely bathed in blinding intensity of it, literally, to me it would have been my worst nightmare being in there with no choice but just shut your eyes to try to dim it out. Have you ever tried that, in a really bright blue LED glare at night... it doesn't go away, it shines right through our eyelids, at least it does my sixty year old eyelids. I have eye retinal problems now, manageable, but there nonetheless, I have to be careful now about exposure. To me it looks like prolonged exposure to high energy LEDs takes its toll. I have a monitor shaped like a radar antenna, which effectively focuses all the pixiels on the user, that I dare not turn up to more than 15-20%, as I've seen my face in cameras on conference calls, even at that level, lit up like it was floodlit, these things are getting crazy imho.
