When we left the German Colony with my mother car yesterday (28.10.2012 dd.mm.yy), I have seen a floodlight near one of the restaurants, that looked to have a daylight MH lamp, that seems to be an indium lamp, based on its color.
When I used my CD-R, in order to see the spectrum of that floodlight, what that I have seen, was actually the spectrum of the experimental Osram HBI short-arc indium lamp (Unusually wide indium blue line with a wide re-absorption dark band at its center (same width and appearance of the sodium line in HPS lamps), with a strong background molecular continum).
Unfortunately, I couldn't capture this unusual spectrum with my camera, because I was inside the car, and it usually take >1 min, to arrange exposure time, shutter size, zoom and manual focus, and photograph the spectrum from my CD-R.
