Kino Flo conversion question

I was going to rent a 4' x 4' Kino Flo light fixture in a few weeks. Seeing as how this will be my first time using fluorescent lights, I was wondering if there was a site (or if any of you knew) how many watts certain Kino flo fixtures put out, and also the lumen output on Kino's compared to that of tungsten lights. (A friend of mine told me that a fluorescents put out the equivalent of 3 times the amount of watts of a tungsten light - so a 200w fluoro would be equal to a 600w tungsten...does this sound right??). Can someone help me out with these conversions (with watts per lumen, etc) ???

Thanks!
 
Fluorescents put out 4x as many lumens per watt as tungsten lights do. However, they do so in an inherently "soft" pattern, with very quick light falloff. A small tungsten par fixture could light up something across the room, a fluorescent couldn't do that. They're very different types of light because of that. The equivalency really only works if you put that tungsten light in a softbox.

For info (including photometrics) everything you'll want to know is over at http://www.kinoflo.com
 
This comment is founded from eyeballing it and not scientific evaluation:

I think an 80W 4Bank Flo is about the same output as an Arrilite 1K with Chimera and both layers of diffusion snapped in.. as the softbox cuts output big time on the Arrilite...

Hope this helps.
 
I am thinking about selling my Hedler lights with softboxes and substituting with Fluorescents. I light people mostly, and sometimes subjects have a hard time posing or acting in front of my lights. They are 2500w, 2500w, and 1000w. The big lights are hot, too warm, consume lots of energy, are too bright for many subjects to be comfortable. Also, they are 3200k so I can't mix with external lights. I've been playing with a small 150w fluorescent. It's not enough to illuminate a scene but when enough natural light comes in, it does a great job at enhancing some spors. I wass wandering if I could do all my woth on larger Fluorescents for subjects. I always use soft lights and I'd like to know if any could work from a battery.
