Mentioning to a tech in anothertheatre I was currently "Gelling" some cycs, he commented on how old fashioned. I'm guessing he was running multicolor fixtures.
According my scant knowledge LEDs produce very narrow emission bands. Looking a spetral scan one would see very narrow red, green and blues popping up around 600, 540 and 480nm without much in between.
This means colors on stage in between these might not get lit correctly e.g. a yellow shirt (580nm). A spectral graph of a tungsten bulb on the other hand has a very wided emission spectra thus lighting a wider range of colored objects.
I know we now have amber and white LEDs and even ones with lime in to help broaden spectra. So my question is: are LEDs ready to completelty replace more conventional tungsten stage lights?
