Put a 10% transmission factor
gel in a
source four at the standard 575W, like a good red (12% trans), blue (8% trans), or green (13% trans)
cyc silk, and tell me how the difference is then against the LED's with the same color with a spreader
lens in them. Even the amber cyc silk is only 32% trans (all of these numbers have been straight out of the
rosco swatchbook sitting on my
desk).
I have done this test against a few LED products. The LED's are about equal with the S4.
This is where most people don't see how LED's are already working so well.
