I didn't use any boxes etc... - I just used the lights on an adapter that lets you screw the bulb into one end and has a standard plugin on the other end - I did 6500K lights, I would suggest something that doesn't leave a shadow pattern on anyone - something like a spiral half dome shape or something (not the easiest for packing) but doesn't throw any weird shadows from the shape of the bulb.

you could look online for something that's dimmable - but I've had a hard time finding any. I'm looking at getting a separate case that I'll use for hauling the bulbs in - at 6500 and 3200 K depending on the light that I'm having to mix with it - then have a bag with a couple of stands and maybe a bar light or two for longer group type shots.

Have to see what I end up with - but I'll just have it all in a case that is foam padded and can custom fit my stuff - and I'll just take it along to the shoots - only a few min to setup and no waiting for them to cool down either. It's a pretty slick little deal - and gives a much better look for my shooting. However I was mixing 6500K with 3200K on this shoot and there were a couple of yellowed areas - so I just threw on the 6ccAV filter (could do the same with the Color Correctors in Vegas but it's not as fast as this 6ccAV filter - whew - man that does it easy). Took and changed that color to match the "correct" lighting that I had in a min or less, and then dropped that preset on the preview monitor cuz it was on all the diff. talking heads.

Hope that helps

Ah,
so you're using compact fluoros with integral ballasts?
I don't think you'll find any that are dimmable easily. To pull that trick you need tubes that use a separate electronic ballast that is dimmable.
Just one tip from Bob's School of Learning it the Hard Way. Don't mix lights of different colour temperature! You end up with shadows etc with a color cast and that's a nightmare to correct.
I did one shoot in our front office / studio and there's this little fluro light that's "natural" not Daylight like the rest of my lighting setup, looked just fine on the day but when I'm editing this stuff I'm thinking, why has the white haired talent got a green tinge to his hair? You guessed it, that not designed for video fluro light.

The moral to this, if you're not using tubes specifically designed for lighting video / film use all the same ones and if possible run them all for the same time, the green phosphors fade faster than the rest. Possibly feeding the light through a softbox will diminish this to some extent, never used one so I cannot be certain.

This is from November - might be of intrest here.

Modern, Economical Lighting Solutions for Large Green Screen Areas.

The basic idea is this: We basically used the 4-tube banks right out of the box from the store. So far, we have four banks, two on the sides and two up high in our array. The stock fixtures at the lumber store were adequate and we built sturdy but simple custom mounts. Since they are always used in the same position to light our wall, they also didn't need to be mounted in any fancy way either. After a little experimentation, we got everything just right, for well under $200
