drawstuf99 said:As footer mentions, try doing some sort of color correction. The lights usually give off an old amber color, unlike the source fours which actually burn dang close to white. Try adding some blue that will mix with the amber to make a more white color, then gel to get the same color as the source four. Or add amber to a S4, either way.
I am not so sure, but with our Juniors, they start to lose their intensity quite fast as you get farther from your subject, somewhat unlike the regular 19* ones, for example. So this may help you with matching intensity. That could be just a bad bulb in our few juniors, but it seems that it's worked that way for me at least.
