I used my 1k Lowel hot lights for years . . . until I discovered my first strobe. Now I use mixed lights with my D100 -- hot (with and without gels) for backgrounds and hair light, strobes for key and fill. Finally, I can turn off the air conditioner and save some money. Later this year, I may eliminate the hot lights totally . . . but cheap effective habits are damn hard to break.
Shot of Sandra below was taken after a very fast sunset. I used a Lowel 1k hot light to provide golden background fill and bounced my SB-80DX flash into a gold and silver umbrella to light the foreground and model.
