Do they really? I thought only the fresnel head had a dim modeling light, while the bare bulb head was better suited for use inside most modifiers. Is this incorrect? Really curious what your experience has been, as I love the small form factor for portability. This is something I definitely struggle with. Not to say that I've mastered other parts of portrait lighting - I can get a decent photo with appropriate key, fill, and background light placement and power. But most of my portraits seem to fit into 2 categories: either it looks like it could benefit from a hair light, or I wish I didn't try to add a hair light.
