First Time Lighting - Sort Of

What I found kind of odd though was that they didn't provide as much light as I expected. The really brightened up the room and dialated my pupils like crazy; but shooting at ISO 100 F/4.0 I had to expose for 1/10 of a second. So I grabbed my light meter and set it up as if I was using my XL2 - 320 ASA and 24 FPS (Actually I'd probably use 48 FPS, but that didn't occur to me last night) and the readout was something like F/3.6.
Now depending on the lens I'm using and the zoom I'm at that F-Stop shouldn't be a problem, especially because I prefer to shoot wide open to minimize DoF; but I guess I just expected the light to be more intense than that - based on what my (untrained) eyes were telling me. So I guess my question is: Is this normal? In lighting a scene are you lighting it to this "low" level of light despite what the eye sees? Or is it just that a combined 1500W isn't a whole hell of a lot?

An ASA 100 at F4 requires a generous amount of light.

hard light tends to look brighter than it is, especially if you look into the light, while the opposite is true for very soft light. 1500 watts of light is more than enough for a small subject even at a low asa but very little for an entire room.
