My stuff is a bit of a mix. At work, I have 4 Photogenic StudioMaster packs and heads (yes, the old S-200 packs!), and for my traveling kit, I use 5 White Lightning monolights, 2 10000 and 3 5000 units. If I were to be buying new lights now, I'd probably buy a few of the Alien Bee 800's and 1600's.
