I've currently 2 Einstein's, 2 DB800's and 1 DB400. It seems about 1 in 5 shoots I've wished for a DB200 (1.25ws) or even a DB100 or two. In some cases moving a light back lowers the power easily but in others it's a bit more of a pain. I was doing a shoot with someone holding a candelabra the other day and simply couldn't turn down low enough. Moving the light back was a problem both for space and it changed the lightl considerably (7" reflector w/ 10° grid). I should have gone in search of my ND gel but that's it's own pain to cut and get on with no spill. And then keep replacing when it fades. I should play w/ the modeling lights more so that I can use them in these situations but they do put out a different light than the strobe and models respond differently under them.
